Definitions
- the present invention concerns an obstruction for mounting along a perimeter of a vessel, such as a merchant or naval ship, or marine installation, such as an oil rig or other marine platform.
- the present invention also concerns a system for protecting the perimeter of a vessel or marine installation against unauthorized potential boarders, such as pirates, stowaways and activists, as well as a vessel or marine installation comprising such a system, and a method of protecting the perimeter of a vessel or marine installation.
- the unauthorized potential boarders may approach a ship or platform, for example, in one or more smaller, high-speed boats equipped with a variety of ladders, climbing poles, grappling hooks and ropes. They may bring such a boat alongside the larger ship or platform, raise a ladder or climbing pole from the boat up the side of the larger ship or platform and attempt to board it by climbing the ladder or pole to gain access to a deck of the ship or platform. They may also attempt to throw a grappling hook attached to a rope on to the deck in order to catch hold of an item fixed to the deck, thereby allowing them to scale the rope.
- vessels and marine installations further comprise an upstanding plate running along the edge of the deck.
- a plate which is commonly called a fishplate, is designed to prevent objects on the deck from sliding off the edge of the deck and falling overboard, if the deck departs from horizontal due to motion of the vessel or marine installation or if the deck is washed by waves or buffeted by adverse weather.
- CN 202935562 U describes a defensive device which can be hung over a fishplate on an outboard or seaward side of a vessel, in order to deter unauthorized potential boarders.
- the top edge of the fishplate can provide a location for an unauthorized potential boarder to attach a hook or to gain a handhold in an attempt to board the vessel or marine installation.
- the fishplate can also interfere with the mounting of security bulwarks along the perimeter railing. This is especially true if the security bulwarks extend substantially the whole height of the perimeter railing or beyond the edge of the deck in a seaward direction at a location near to or below the bottom edge of the railing. Very little consideration seems to have been given in the prior art to the solution of these problems.
- the present invention aims to address these and other problems. It also aims to provide an obstruction for mounting along a perimeter of a vessel, a perimeter protection system for a vessel or marine installation comprising a plurality of such obstructions, a vessel or marine installation comprising a plurality of such obstructions, and a method of protecting a perimeter of a vessel or marine installation using a plurality of such obstructions.
- the present invention provides an obstruction for mounting along a perimeter of a vessel or marine installation, wherein the vessel or marine installation comprises a deck having a perimeter railing and an upstanding plate along an edge of the deck.
- the obstruction has an elongate body comprising a longitudinal groove for receiving a lowermost course of rails of the perimeter railing, and a tongue for overhanging the plate on an outboard or seaward side thereof.
- the tongue comprises a rear surface intended to face in an inboard direction when the obstruction is mounted along the perimeter of the vessel or marine installation.
- a separation, s, between the rear surface of the tongue and a centreline of the longitudinal groove is between 30 and 300 mm, and the centreline of the longitudinal groove and the separation, s, together define a plane which subtends an angle, ⁇ , of between 90 and 135 degrees to the rear surface of the tongue.
- the fishplate can be protected from unauthorized potential boarders trying to attach a hook to the fishplate or to gain a handhold on the top edge of the fishplate.
- the combination of features of the separation, s, and the angle, ⁇ , of the obstruction as described above allows the obstruction to protect a wide variety of different possible heights of fishplate and different possible distances of the perimeter railing across the deck to the fishplate, in a manner to be described in greater detail below.
- a plurality of security bulwarks may be mounted along the perimeter railing above a plurality of such obstructions to provide the vessel or marine installation with a perimeter protection system, without the need to employ security bulwarks which extend substantially the whole height of the perimeter railing or beyond the edge of the deck in a seaward direction at a location near to or below the bottom edge of the railing.
- security bulwarks which extend approximately only two-thirds or three-quarters of the height of the perimeter railing from the top thereof may be used instead.
- the tongue of the obstruction has a thickness, t, which tapers in a direction away from the longitudinal groove. This helps to maintain the orientation of the obstruction with the tongue in a downwardly pointing direction when the obstruction is in use. It also has the advantage of shifting the centre of mass of the obstruction in a more inboard direction when the obstruction is in use, which reduces the chance of the obstruction being accidentally lost overboard in adverse weather or sea conditions.
- the longitudinal groove is adapted for rotation of the obstruction about the lowermost course of rails, so that the obstruction can accommodate plates of different heights along the edge of the deck.
- the obstruction further comprises an upper surface intended to face upwards when the obstruction is mounted along the perimeter of the vessel or marine installation, wherein the upper surface is convexly curved in a direction of the depth of the obstruction.
- This has the advantage of ensuring that the upper surface maintains a substantially constant height above the deck if the obstruction is rotated to suit different heights of fishplate, thereby making it less likely to interfere with any security bulwark mounted above it on the perimeter railing. It also helps to prevent the upper surface of the obstruction from being used by an unauthorized potential boarder as a location for a handhold.
- the upper surface is preferably also substantially smooth. This makes it harder for the upper surface of the obstruction to be used by an unauthorized potential boarder as a location for a handhold.
- the tongue comprises a front surface intended to face in a seaward direction when the obstruction is mounted along the perimeter of the vessel or marine installation, which front surface is substantially smooth. This makes it harder for an unauthorized potential boarder to gain a hand or foothold on the front surface.
- the obstruction further comprises an attachment facility proximate the longitudinal groove for attaching the obstruction to the lowermost course of rails. This allows the obstruction to be securely fastened to the perimeter railing, even though the obstruction cannot be readily attached to the fishplate.
- the attachment facility preferably comprises one or more through-holes in the obstruction. This has the advantage of allowing the obstruction to be attached to the perimeter railing quickly and easily by tying.
- the obstruction further comprises an anti-rotation device for impeding rotation of the obstruction about the lowermost course of rails.
- an anti-rotation device for impeding rotation of the obstruction about the lowermost course of rails.
- the anti-rotation device preferably comprises one or more through-holes in the tongue. This allows the obstruction to be tied to another, adjacent, similar obstruction or to one or more vertical stanchions or support stays of the perimeter railing, for example.
- the obstruction preferably has a width, w, of between 0.70 and 1.50 metres, more preferably of between 0.80 and 1.40 metres, and most preferably of between 0.90 and 1.30 metres.
- a width has the advantage of being best suited to fit in the spaces between adjacent vertical stanchions of perimeter railings which are commonly encountered.
- the tongue has a height, h, of between 200 and 600 mm, more preferably of between 250 and 500 mm, and most preferably of between 300 and 400 mm.
- h has the advantage of being best suited to the different possible distances of the perimeter railing from the fishplate, across the deck, which are commonly encountered.
- the obstruction is constituted of one or more materials which are resistant to weather and seawater, such as inert plastics materials.
- the obstruction may be made of high density polyethylene (HDPE) and/or of glass reinforced nylon, both of which also have good strength and rigidity.
- HDPE high density polyethylene
- glass reinforced nylon both of which also have good strength and rigidity.
- the present invention also provides a perimeter protection system comprising a plurality of obstructions according to the first aspect of the invention, and a plurality of security bulwarks for mounting to the perimeter railing of the vessel or marine installation, above the obstructions.
- the security bulwarks may, for example, be of a type shown and described in UK patent no. GB 2 531 232 B , also in the name of the present applicant and the contents of which are incorporated herein by reference.
- the present invention further provides a vessel or marine installation comprising a plurality of obstructions according to the first aspect of the invention arranged side-by-side and adjacent to each other along the perimeter of the vessel or marine installation, and a plurality of security bulwarks arranged side-by-side and adjacent to each other along the perimeter railing of the vessel or marine installation, above the obstructions.
- a vessel or marine installation comprising a plurality of obstructions according to the first aspect of the invention arranged side-by-side and adjacent to each other along the perimeter of the vessel or marine installation, and a plurality of security bulwarks arranged side-by-side and adjacent to each other along the perimeter railing of the vessel or marine installation, above the obstructions.
- the vessel or marine installation may comprise cargo protected by the plurality of obstructions and the plurality of security bulwarks.
- the present invention also provides a method of protecting a perimeter of a vessel or marine installation, wherein the vessel or marine installation comprises a deck having a perimeter railing and an upstanding plate along an edge of the deck.
- the method comprises positioning a plurality of obstructions according to the first aspect of the invention side-by-side and adjacent to each other along the perimeter of the vessel or marine installation, receiving a lowermost course of rails of the perimeter railing in the longitudinal grooves of the obstructions, and hanging the tongues of the obstructions over the plate on an outboard or seaward side thereof.
- the method further comprises attaching at least one of the obstructions to the perimeter railing.
- the obstructions may instead be attached to other items on the vessel or marine installation, such as to an obstacle permanently located on the deck, like a cleat or bitt.
- the method also comprises impeding rotation of at least one of the obstructions about the lowermost course of rails. This is advantageous because it helps to prevent the obstruction from being flipped up to expose the top edge of the fishplate.
- the method further comprises positioning a plurality of security bulwarks side-by-side and adjacent to each other along the perimeter railing of the vessel or marine installation, above the obstructions. This is advantageous because both the fishplate and the railing can then be protected against unauthorized potential boarders.
- Figs. 1 and 2 respectively show views from an outside or seaward side and from an inside or deck side of a representative part of a perimeter railing 20 of a vessel or marine installation. Part of a side of the vessel or marine installation can be seen labelled with reference numeral 52.
- the perimeter railing 20 comprises a plurality of courses of rails, which include a topmost handrail 201, a middle course of rails 202 and a lowest course of rails 203. At regular intervals along the perimeter railing 20 are a plurality of vertical stanchions 204. Regulations require that the vertical stanchions 204 are spaced no more than 1.5 metres apart.
- the perimeter railing 20 is mounted on a deck 51 of the vessel or marine installation.
- the overall height, g, of the railing 20 from the deck 51 to the topmost handrail 201 is required by regulations to be at least 1 metre.
- the separation, f, of the lowest course of rails 203 from the deck 51 is also required by regulations to be no more than 230 mm.
- the middle course of rails 202 is positioned approximately equidistant between the topmost handrail 201 and the lowest course of rails 203.
- a gap between the topmost handrail 201 and the middle course of rails 202 or between the middle course of rails 202 and the lowest course of rails 203 is given by (g - f)/2, from which must also be subtracted the thickness of the courses of rails themselves.
- Each gap is therefore usually not more than 500 mm in height, and, in practice, is considerably less than this.
- a vertical lip called a fishplate 53, the height of which depends upon the type of vessel or marine installation on which the railing 20 is mounted, but which, in general, is between about 90 and about 400 mm in height.
- a distance across the deck 51 of the perimeter railing 20 from the fishplate 53 is not defined by regulations and may therefore also vary depending upon the type of vessel or marine installation on which the railing 20 is mounted. Typically, however, this distance across the deck 51 is up to about 300 mm.
- the perimeter railing 20 is upheld at regular intervals by a plurality of support stays 205, one of which may be seen in Fig. 2 .
- Regulations require that there must be a minimum of one support stay 205 for every three vertical stanchions 204, although it is common for there to be a support stay 205 for every other stanchion 204.
- Also shown in Fig. 2 is a representative example of an obstacle 23 permanently located on the inside or deck side of the railing 20.
- Such obstacles include accommodation ladders, cleats and bitts.
- Figs. 3 , 4 and 5 show an embodiment of an obstruction 10 suitable for mounting along a perimeter of a vessel or marine installation, when the vessel or marine installation comprises a deck 51 having a perimeter railing 20 and an upstanding plate 53 along an edge of the deck, such as are shown in Figs. 1 and 2 .
- the obstruction 10 has an elongate body which comprises a longitudinal groove 12 for receiving the lowermost course of rails 203 of the perimeter railing 20, and a tongue 14 for overhanging the plate 53 on an outboard or seaward side of the plate.
- the tongue 14 comprises a rear surface 142 and a front surface 144.
- the rear surface 142 is intended to face in an inboard direction of the vessel or marine installation when the obstruction 10 is mounted along its perimeter, and the front surface is intended to face in an outboard or seaward direction.
- the obstruction 10 also comprises an upper surface 16 intended to face upwards when the obstruction 10 is mounted along the perimeter of the vessel or marine installation and an underside 18, which is opposite thereto and in which the longitudinal groove 12 is formed.
- a separation, s, between the rear surface 142 of the tongue 14 and a centreline of the longitudinal groove 12, which is labelled X-X' in Fig. 4 is between 30 and 300 mm.
- the obstruction 10 can be positioned such that the lowermost course of rails 203 is received in the longitudinal groove 12 and the tongue 14 overhangs the fishplate 53 on an outboard or seaward side thereof.
- the tongue 14 will point downwardly, provided that the fishplate 53 is not significantly taller than the separation, f, of the lowest course of rails 203 from the deck 51.
- “Not significantly taller” here means that the height of the fishplate 53 is not more than about 30 mm greater than the separation, f. In such a case, therefore, the top edge of the fishplate 53 is covered by the tongue 14 and can no longer provide an unauthorized potential boarder with a location to attach a hook or to gain a handhold in an attempt to board the vessel or marine installation.
- the tongue 14 would instead point upwardly on an outboard or seaward side of the fishplate 53.
- the tongue 14 would then itself provide a possible location for an unauthorized potential boarder to attach a hook or to gain a handhold.
- the top edge of the fishplate 53 can instead be rendered inaccessible to an unauthorized potential boarder by mounting a security bulwark along the perimeter railing 20 at a location above the fishplate 53.
- an overhang on the underside of the security bulwark on the outboard or seaward side thereof prevents access to the top edge of the fishplate 53.
- the fishplate 53 is taller than the separation, f, the fishplate itself completely covers the gap between the lowermost course of rails 203 and the deck 51.
- the variety of different possible distances across the deck 51 of the perimeter railing 20 from the fishplate 53 and the variety of different possible heights of the fishplate are both accommodated by a combination of the two features of the obstruction 10 mentioned above: namely, that the longitudinal groove 12 is separated from the rear surface 142 of the tongue by between 30 and 300 mm, and that the angle, ⁇ , is an obtuse angle of between 90 and 135 degrees.
- the obstruction 10 is able to maintain a downward pointing orientation of the tongue 14 for a wide variety of different possible heights of fishplate and different possible distances of the perimeter railing 20 from the fishplate 53, across the deck 51.
- the ability of the obstruction 10 to maintain the downward pointing orientation of the tongue 14 is further enhanced by another feature of this embodiment of the obstruction 10, which is that the tongue 14 has a thickness, t, which tapers in a direction away from the longitudinal groove 12.
- the tapering thickness, t, of the tongue 14 means that the front surface 144 points downwards more steeply than the rear surface 142 thereof.
- the longitudinal groove 12 has a smoothly curved, concave profile, as may best be seen in Fig. 5 .
- the longitudinal groove 12 is adapted for rotation of the obstruction 10 about the lowermost course of rails 203, whereby the obstruction 10 may easily accommodate fishplates of different heights along the edge of the deck.
- the upper surface 16 is convexly curved in a direction D-D' of the depth of the obstruction 10. This has two advantages, as follows. Firstly, it ensures that the upper surface 16 maintains a substantially constant height above the deck 51 as the obstruction 10 is rotated to suit different heights of fishplate and different separations, f, of the lowermost course of rails 203 from the deck 51.
- the obstruction 10 is less likely to interfere with a security bulwark mounted above it on the perimeter railing 20. Secondly, however, it also helps to prevent the upper surface 16 of the obstruction 10 from being used by an unauthorized potential boarder as a location for a handhold. For the same reason, both the upper surface 16 and the front surface 144 are substantially smooth.
- the obstruction 10 further comprises an attachment facility 11 proximate the longitudinal groove 12.
- the attachment facility 11 comprises a plurality of through-holes 112 formed in the obstruction 10, allowing the obstruction 10 to be tied to the lowermost course of rails 203 for example, and/or to one or more of the vertical stanchions 204 of the perimeter railing 20. It may also be tied to an obstacle 23 permanently located on the deck of the vessel or marine installation, such as that which is represented in Fig. 2 .
- the attachment facility 11 could instead comprise one or more clips for example, for clipping the obstruction 10 to the lowermost course of rails 203.
- the obstruction 10 therefore further comprises an anti-rotation device 13 for impeding any such undesired rotation of the obstruction 10 about the lowermost course of rails 203.
- the anti-rotation device 13 comprises a plurality of through-holes 132 formed in the tongue 14.
- the obstruction 10 allows the obstruction 10 to be tied to another, adjacent, similar obstruction or to one or more of the vertical stanchions 204 or support stays 205, for example.
- the anti-rotation device 13 could instead comprise a tang on the rear surface 142 of the tongue 14 for engagement with the fishplate 53, one or more arms for engagement with the vertical stanchions 204 or support stays 205, or one or more clips for clipping the obstruction 10 to an adjacent, similar obstruction.
- the obstruction 10 has a width, w, of approximately 980 mm. Since the vertical stanchions 204 of the perimeter railing 20 are spaced no more than 1.5 metres apart, and are often spaced 1 metre apart, the obstruction 10 can therefore usually fit comfortably between two adjacent stanchions 204. If the obstruction is made of high density polyethylene (HDPE) or of glass reinforced nylon, a small notch may easily be cut into it to allow the obstruction 10 to be mounted on the lowermost course of rails 203 across one of the vertical stanchions 204. Thus, a plurality of such obstructions may be arranged side-by-side and adjacent to each other along the perimeter of the vessel or marine installation by cutting notches into them at positions which correspond to the locations of the vertical stanchions 204.
- HDPE high density polyethylene
- a plurality of such obstructions may be arranged side-by-side and adjacent to each other along the perimeter of the vessel or marine installation by cutting notches into them at positions which correspond to the locations of the vertical stanchions 204.
- the obstruction 10 shown in Figs. 3 , 4 and 5 has a height, h, of approximately 300 mm, and the separation, s, between the rear surface 142 of the tongue 14 and the centreline X-X' of the longitudinal groove 12 is approximately 82 mm. These dimensions are sufficient to allow the obstruction 10 to overhang a wide variety of different possible heights of fishplate for different possible distances of the perimeter railing 20 across the deck 51 to the fishplate 53.
- the angle, ⁇ is approximately 103 degrees.
- Figs. 6 and 7 respectively show views from an outside or seaward side and from an inside or deck side of an embodiment of a perimeter protection system 100 mounted on a perimeter railing 20 of a vessel or marine installation, such as that shown in Figs. 1 and 2 .
- the perimeter protection system 100 comprises a plurality of obstructions 10a, 10b of the type shown and described above in relation to Figs. 3 , 4 and 5 , and a plurality of security bulwarks 1a, 1b, 1c for mounting to the perimeter railing 20 of the vessel or marine installation, above the obstructions.
- Each of the security bulwarks 1a, 1b, 1c may, for example, be of a type shown and described in UK patent no.
- the perimeter protection system 100 may further comprise one or more of another type of obstruction for positioning in a recess between an adjacent pair of the security bulwarks 1a, 1b and of a type shown and described in UK patent no.

- the vessel or marine installation is shown in Figs. 6 and 7 as having fishplates of two different heights, which are respectively labelled 53a, 53b. This is to show how the orientation of the obstructions 10a, 10b adjusts to suit the different heights of the fishplates.

- the plurality of obstructions 10a, 10b can be arranged side-by-side and adjacent to each other along the perimeter of the vessel or marine installation, with the plurality of security bulwarks 1a, 1b, 1c arranged side-by-side and adjacent to each other along the perimeter railing 20 of the vessel or marine installation, above the obstructions.
- the plurality of obstructions 10a, 10b and the plurality of security bulwarks 1a, 1b, 1c may be brightly coloured to advertise the presence of the perimeter protection system 100 to unauthorized potential boarders and to deter them from approaching the vessel or marine installation. Preferably, they are coloured safety orange.
- the vessel or marine installation may further comprise cargo protected by the plurality of obstructions 10a, 10b and the plurality of security bulwarks 1a, 1b, 1c of the perimeter protection system 100.

Description
- The present invention concerns an obstruction for mounting along a perimeter of a vessel, such as a merchant or naval ship, or marine installation, such as an oil rig or other marine platform. The present invention also concerns a system for protecting the perimeter of a vessel or marine installation against unauthorized potential boarders, such as pirates, stowaways and activists, as well as a vessel or marine installation comprising such a system, and a method of protecting the perimeter of a vessel or marine installation.
- With increased criminality at sea, there has been a corresponding increase in the need for sea-going vessels and marine installations to be protected against such unauthorized potential boarders. The unauthorized potential boarders may approach a ship or platform, for example, in one or more smaller, high-speed boats equipped with a variety of ladders, climbing poles, grappling hooks and ropes. They may bring such a boat alongside the larger ship or platform, raise a ladder or climbing pole from the boat up the side of the larger ship or platform and attempt to board it by climbing the ladder or pole to gain access to a deck of the ship or platform. They may also attempt to throw a grappling hook attached to a rope on to the deck in order to catch hold of an item fixed to the deck, thereby allowing them to scale the rope. This has led to the development of a number of different types of security bulwark for protecting the perimeter of vessels and marine installations by aiming to thwart such unauthorized potential boarders. These known security bulwarks are typically mounted over a perimeter railing running along the edge of a deck of the vessel or marine installation.
- On the other hand, many vessels and marine installations further comprise an upstanding plate running along the edge of the deck. Such a plate, which is commonly called a fishplate, is designed to prevent objects on the deck from sliding off the edge of the deck and falling overboard, if the deck departs from horizontal due to motion of the vessel or marine installation or if the deck is washed by waves or buffeted by adverse weather.
-
CN 202935562 U describes a defensive device which can be hung over a fishplate on an outboard or seaward side of a vessel, in order to deter unauthorized potential boarders. - However, the top edge of the fishplate can provide a location for an unauthorized potential boarder to attach a hook or to gain a handhold in an attempt to board the vessel or marine installation. The fishplate can also interfere with the mounting of security bulwarks along the perimeter railing. This is especially true if the security bulwarks extend substantially the whole height of the perimeter railing or beyond the edge of the deck in a seaward direction at a location near to or below the bottom edge of the railing. Very little consideration seems to have been given in the prior art to the solution of these problems.
- The present invention aims to address these and other problems. It also aims to provide an obstruction for mounting along a perimeter of a vessel, a perimeter protection system for a vessel or marine installation comprising a plurality of such obstructions, a vessel or marine installation comprising a plurality of such obstructions, and a method of protecting a perimeter of a vessel or marine installation using a plurality of such obstructions.
- Accordingly, in a first aspect, the present invention provides an obstruction for mounting along a perimeter of a vessel or marine installation, wherein the vessel or marine installation comprises a deck having a perimeter railing and an upstanding plate along an edge of the deck. The obstruction has an elongate body comprising a longitudinal groove for receiving a lowermost course of rails of the perimeter railing, and a tongue for overhanging the plate on an outboard or seaward side thereof. The tongue comprises a rear surface intended to face in an inboard direction when the obstruction is mounted along the perimeter of the vessel or marine installation. A separation, s, between the rear surface of the tongue and a centreline of the longitudinal groove is between 30 and 300 mm, and the centreline of the longitudinal groove and the separation, s, together define a plane which subtends an angle, θ, of between 90 and 135 degrees to the rear surface of the tongue.
- With such an obstruction, the fishplate can be protected from unauthorized potential boarders trying to attach a hook to the fishplate or to gain a handhold on the top edge of the fishplate. The combination of features of the separation, s, and the angle, θ, of the obstruction as described above allows the obstruction to protect a wide variety of different possible heights of fishplate and different possible distances of the perimeter railing across the deck to the fishplate, in a manner to be described in greater detail below.
- Moreover, with the use of such a fishplate protector as this obstruction provides, a plurality of security bulwarks may be mounted along the perimeter railing above a plurality of such obstructions to provide the vessel or marine installation with a perimeter protection system, without the need to employ security bulwarks which extend substantially the whole height of the perimeter railing or beyond the edge of the deck in a seaward direction at a location near to or below the bottom edge of the railing. For example, security bulwarks which extend approximately only two-thirds or three-quarters of the height of the perimeter railing from the top thereof may be used instead. Thus the risk of the fishplate interfering with the mounting of security bulwarks along the perimeter railing can be avoided.
- Preferably, the tongue of the obstruction has a thickness, t, which tapers in a direction away from the longitudinal groove. This helps to maintain the orientation of the obstruction with the tongue in a downwardly pointing direction when the obstruction is in use. It also has the advantage of shifting the centre of mass of the obstruction in a more inboard direction when the obstruction is in use, which reduces the chance of the obstruction being accidentally lost overboard in adverse weather or sea conditions.
- Preferably, the longitudinal groove is adapted for rotation of the obstruction about the lowermost course of rails, so that the obstruction can accommodate plates of different heights along the edge of the deck.
- Preferably, the obstruction further comprises an upper surface intended to face upwards when the obstruction is mounted along the perimeter of the vessel or marine installation, wherein the upper surface is convexly curved in a direction of the depth of the obstruction. This has the advantage of ensuring that the upper surface maintains a substantially constant height above the deck if the obstruction is rotated to suit different heights of fishplate, thereby making it less likely to interfere with any security bulwark mounted above it on the perimeter railing. It also helps to prevent the upper surface of the obstruction from being used by an unauthorized potential boarder as a location for a handhold.
- If so, the upper surface is preferably also substantially smooth. This makes it harder for the upper surface of the obstruction to be used by an unauthorized potential boarder as a location for a handhold.
- It is also preferred for the tongue to comprise a front surface intended to face in a seaward direction when the obstruction is mounted along the perimeter of the vessel or marine installation, which front surface is substantially smooth. This makes it harder for an unauthorized potential boarder to gain a hand or foothold on the front surface.
- Preferably, the obstruction further comprises an attachment facility proximate the longitudinal groove for attaching the obstruction to the lowermost course of rails. This allows the obstruction to be securely fastened to the perimeter railing, even though the obstruction cannot be readily attached to the fishplate.
- If so, the attachment facility preferably comprises one or more through-holes in the obstruction. This has the advantage of allowing the obstruction to be attached to the perimeter railing quickly and easily by tying.
- Preferably, the obstruction further comprises an anti-rotation device for impeding rotation of the obstruction about the lowermost course of rails. This has the advantage of preventing an unauthorized potential boarder from being able to flip the tongue of the obstruction up, in order to try and gain access to the top edge of the fishplate and use it as a handhold, for example.
- If so, the anti-rotation device preferably comprises one or more through-holes in the tongue. This allows the obstruction to be tied to another, adjacent, similar obstruction or to one or more vertical stanchions or support stays of the perimeter railing, for example.
- The obstruction preferably has a width, w, of between 0.70 and 1.50 metres, more preferably of between 0.80 and 1.40 metres, and most preferably of between 0.90 and 1.30 metres. Such a width has the advantage of being best suited to fit in the spaces between adjacent vertical stanchions of perimeter railings which are commonly encountered.
- Preferably, the tongue has a height, h, of between 200 and 600 mm, more preferably of between 250 and 500 mm, and most preferably of between 300 and 400 mm. Such a height has the advantage of being best suited to the different possible distances of the perimeter railing from the fishplate, across the deck, which are commonly encountered.
- Preferably, the obstruction is constituted of one or more materials which are resistant to weather and seawater, such as inert plastics materials. For example, the obstruction may be made of high density polyethylene (HDPE) and/or of glass reinforced nylon, both of which also have good strength and rigidity.
- In a second aspect, the present invention also provides a perimeter protection system comprising a plurality of obstructions according to the first aspect of the invention, and a plurality of security bulwarks for mounting to the perimeter railing of the vessel or marine installation, above the obstructions. The security bulwarks may, for example, be of a type shown and described in UK patent no.
GB 2 531 232 B - In a third aspect, the present invention further provides a vessel or marine installation comprising a plurality of obstructions according to the first aspect of the invention arranged side-by-side and adjacent to each other along the perimeter of the vessel or marine installation, and a plurality of security bulwarks arranged side-by-side and adjacent to each other along the perimeter railing of the vessel or marine installation, above the obstructions. Thus the perimeter of the vessel or marine installation can be protected by a plurality of such obstructions and a plurality of such security bulwarks working together with each other to protect both the perimeter railing and the fishplate against unauthorized potential boarders.
- The vessel or marine installation may comprise cargo protected by the plurality of obstructions and the plurality of security bulwarks.
- In a fourth aspect, the present invention also provides a method of protecting a perimeter of a vessel or marine installation, wherein the vessel or marine installation comprises a deck having a perimeter railing and an upstanding plate along an edge of the deck. The method comprises positioning a plurality of obstructions according to the first aspect of the invention side-by-side and adjacent to each other along the perimeter of the vessel or marine installation, receiving a lowermost course of rails of the perimeter railing in the longitudinal grooves of the obstructions, and hanging the tongues of the obstructions over the plate on an outboard or seaward side thereof.
- Preferably, the method further comprises attaching at least one of the obstructions to the perimeter railing. This is preferred because it is easiest. However, in alternative possible embodiments, the obstructions may instead be attached to other items on the vessel or marine installation, such as to an obstacle permanently located on the deck, like a cleat or bitt.
- In a preferred embodiment, the method also comprises impeding rotation of at least one of the obstructions about the lowermost course of rails. This is advantageous because it helps to prevent the obstruction from being flipped up to expose the top edge of the fishplate.
- Preferably, the method further comprises positioning a plurality of security bulwarks side-by-side and adjacent to each other along the perimeter railing of the vessel or marine installation, above the obstructions. This is advantageous because both the fishplate and the railing can then be protected against unauthorized potential boarders.
- Further features and advantages of the present invention will become apparent from the following detailed description, which is given by way of example and in association with the accompanying drawings, in which:
-
Fig. 1 is a perspective view from an outside or seaward side of a part of a perimeter railing of a vessel or marine installation; -
Fig. 2 is a perspective view from an inside or deck side of the part of a perimeter railing shown inFig. 1 ; -
Fig. 3 is a first perspective view of an embodiment of an obstruction; -
Fig. 4 is a second perspective view of the obstruction shown inFig. 3 ; -
Fig. 5 is a side profile view of the obstruction shown inFigs. 3 and4 ; -
Fig. 6 is a perspective view from an outside or seaward side of an embodiment of a perimeter protection system; and -
Fig. 7 is a perspective view from an inside or deck side of the perimeter protection system shown inFig. 6 . -
Figs. 1 and2 respectively show views from an outside or seaward side and from an inside or deck side of a representative part of aperimeter railing 20 of a vessel or marine installation. Part of a side of the vessel or marine installation can be seen labelled withreference numeral 52. Theperimeter railing 20 comprises a plurality of courses of rails, which include atopmost handrail 201, a middle course ofrails 202 and a lowest course ofrails 203. At regular intervals along theperimeter railing 20 are a plurality ofvertical stanchions 204. Regulations require that thevertical stanchions 204 are spaced no more than 1.5 metres apart. Theperimeter railing 20 is mounted on adeck 51 of the vessel or marine installation. The overall height, g, of therailing 20 from thedeck 51 to thetopmost handrail 201 is required by regulations to be at least 1 metre. The separation, f, of the lowest course ofrails 203 from thedeck 51 is also required by regulations to be no more than 230 mm. The middle course ofrails 202 is positioned approximately equidistant between thetopmost handrail 201 and the lowest course ofrails 203. Thus a gap between thetopmost handrail 201 and the middle course ofrails 202 or between the middle course ofrails 202 and the lowest course ofrails 203 is given by (g - f)/2, from which must also be subtracted the thickness of the courses of rails themselves. Each gap is therefore usually not more than 500 mm in height, and, in practice, is considerably less than this. - Outside the
railing 20 at the edge of thedeck 51 is a vertical lip called afishplate 53, the height of which depends upon the type of vessel or marine installation on which therailing 20 is mounted, but which, in general, is between about 90 and about 400 mm in height. A distance across thedeck 51 of theperimeter railing 20 from thefishplate 53 is not defined by regulations and may therefore also vary depending upon the type of vessel or marine installation on which therailing 20 is mounted. Typically, however, this distance across thedeck 51 is up to about 300 mm. - The
perimeter railing 20 is upheld at regular intervals by a plurality of support stays 205, one of which may be seen inFig. 2 . Regulations require that there must be a minimum of one support stay 205 for every threevertical stanchions 204, although it is common for there to be asupport stay 205 for everyother stanchion 204. Also shown inFig. 2 is a representative example of anobstacle 23 permanently located on the inside or deck side of therailing 20. Such obstacles include accommodation ladders, cleats and bitts. -
Figs. 3 ,4 and5 show an embodiment of anobstruction 10 suitable for mounting along a perimeter of a vessel or marine installation, when the vessel or marine installation comprises adeck 51 having aperimeter railing 20 and anupstanding plate 53 along an edge of the deck, such as are shown inFigs. 1 and2 . Theobstruction 10 has an elongate body which comprises alongitudinal groove 12 for receiving the lowermost course ofrails 203 of theperimeter railing 20, and atongue 14 for overhanging theplate 53 on an outboard or seaward side of the plate. Thetongue 14 comprises arear surface 142 and afront surface 144. Therear surface 142 is intended to face in an inboard direction of the vessel or marine installation when theobstruction 10 is mounted along its perimeter, and the front surface is intended to face in an outboard or seaward direction. Theobstruction 10 also comprises anupper surface 16 intended to face upwards when theobstruction 10 is mounted along the perimeter of the vessel or marine installation and anunderside 18, which is opposite thereto and in which thelongitudinal groove 12 is formed. A separation, s, between therear surface 142 of thetongue 14 and a centreline of thelongitudinal groove 12, which is labelled X-X' inFig. 4 , is between 30 and 300 mm. The centreline X-X' of thelongitudinal groove 12 and the separation, s, together define a plane subtending an angle, θ, of between 90 and 135 degrees to therear surface 142 of the tongue, as is shown inFig. 5 . - Thus the
obstruction 10 can be positioned such that the lowermost course ofrails 203 is received in thelongitudinal groove 12 and thetongue 14 overhangs thefishplate 53 on an outboard or seaward side thereof. Thetongue 14 will point downwardly, provided that thefishplate 53 is not significantly taller than the separation, f, of the lowest course ofrails 203 from thedeck 51. "Not significantly taller" here means that the height of thefishplate 53 is not more than about 30 mm greater than the separation, f. In such a case, therefore, the top edge of thefishplate 53 is covered by thetongue 14 and can no longer provide an unauthorized potential boarder with a location to attach a hook or to gain a handhold in an attempt to board the vessel or marine installation. - On the other hand, if the
fishplate 53 is significantly taller than the separation, f, of the lowermost course ofrails 203 from thedeck 51, if theobstruction 10 were again to be positioned such that the lowermost course ofrails 203 was received in thelongitudinal groove 12 with thetongue 14 overhanging thefishplate 53, thetongue 14 would instead point upwardly on an outboard or seaward side of thefishplate 53. Thetongue 14 would then itself provide a possible location for an unauthorized potential boarder to attach a hook or to gain a handhold. In such a case, however, there is no need to use theobstruction 10 at all, since the top edge of thefishplate 53 can instead be rendered inaccessible to an unauthorized potential boarder by mounting a security bulwark along theperimeter railing 20 at a location above thefishplate 53. In such a case, an overhang on the underside of the security bulwark on the outboard or seaward side thereof prevents access to the top edge of thefishplate 53. Moreover, in such a case, since thefishplate 53 is taller than the separation, f, the fishplate itself completely covers the gap between the lowermost course ofrails 203 and thedeck 51. - However, in the case that the
fishplate 53 is not significantly taller than the separation, f, the variety of different possible distances across thedeck 51 of theperimeter railing 20 from thefishplate 53 and the variety of different possible heights of the fishplate are both accommodated by a combination of the two features of theobstruction 10 mentioned above: namely, that thelongitudinal groove 12 is separated from therear surface 142 of the tongue by between 30 and 300 mm, and that the angle, θ, is an obtuse angle of between 90 and 135 degrees. With this combination of features, theobstruction 10 is able to maintain a downward pointing orientation of thetongue 14 for a wide variety of different possible heights of fishplate and different possible distances of theperimeter railing 20 from thefishplate 53, across thedeck 51. - The ability of the
obstruction 10 to maintain the downward pointing orientation of thetongue 14 is further enhanced by another feature of this embodiment of theobstruction 10, which is that thetongue 14 has a thickness, t, which tapers in a direction away from thelongitudinal groove 12. Thus if therear surface 142 of the tongue adopts a downward pointing orientation, the tapering thickness, t, of thetongue 14 means that thefront surface 144 points downwards more steeply than therear surface 142 thereof. - The
longitudinal groove 12 has a smoothly curved, concave profile, as may best be seen inFig. 5 . Thus thelongitudinal groove 12 is adapted for rotation of theobstruction 10 about the lowermost course ofrails 203, whereby theobstruction 10 may easily accommodate fishplates of different heights along the edge of the deck. In contrast, theupper surface 16 is convexly curved in a direction D-D' of the depth of theobstruction 10. This has two advantages, as follows. Firstly, it ensures that theupper surface 16 maintains a substantially constant height above thedeck 51 as theobstruction 10 is rotated to suit different heights of fishplate and different separations, f, of the lowermost course ofrails 203 from thedeck 51. Thus theobstruction 10 is less likely to interfere with a security bulwark mounted above it on theperimeter railing 20. Secondly, however, it also helps to prevent theupper surface 16 of theobstruction 10 from being used by an unauthorized potential boarder as a location for a handhold. For the same reason, both theupper surface 16 and thefront surface 144 are substantially smooth. - To allow the
obstruction 10 to be secured to theperimeter railing 20, theobstruction 10 further comprises anattachment facility 11 proximate thelongitudinal groove 12. In this particular embodiment, theattachment facility 11 comprises a plurality of through-holes 112 formed in theobstruction 10, allowing theobstruction 10 to be tied to the lowermost course ofrails 203 for example, and/or to one or more of thevertical stanchions 204 of theperimeter railing 20. It may also be tied to anobstacle 23 permanently located on the deck of the vessel or marine installation, such as that which is represented inFig. 2 . However, in an alternative possible embodiment of theobstruction 10, theattachment facility 11 could instead comprise one or more clips for example, for clipping theobstruction 10 to the lowermost course ofrails 203. - Even if the
obstruction 10 is securely attached to theperimeter railing 20, rotation of theobstruction 10 about the lowermost course ofrails 203 is undesirable, as this would expose the top edge of thefishplate 53. In such a case, an unauthorized potential boarder might try to flip thetongue 14 of the obstruction up, in order to gain access to the top edge of thefishplate 53 and use it as a handhold, for example. Theobstruction 10 therefore further comprises ananti-rotation device 13 for impeding any such undesired rotation of theobstruction 10 about the lowermost course ofrails 203. In this particular embodiment, theanti-rotation device 13 comprises a plurality of through-holes 132 formed in thetongue 14. These allow theobstruction 10 to be tied to another, adjacent, similar obstruction or to one or more of thevertical stanchions 204 or support stays 205, for example. However, in other alternative possible embodiments of theobstruction 10, theanti-rotation device 13 could instead comprise a tang on therear surface 142 of thetongue 14 for engagement with thefishplate 53, one or more arms for engagement with thevertical stanchions 204 or support stays 205, or one or more clips for clipping theobstruction 10 to an adjacent, similar obstruction. - In the embodiment shown in
Figs. 3 ,4 and5 , theobstruction 10 has a width, w, of approximately 980 mm. Since thevertical stanchions 204 of theperimeter railing 20 are spaced no more than 1.5 metres apart, and are often spaced 1 metre apart, theobstruction 10 can therefore usually fit comfortably between twoadjacent stanchions 204. If the obstruction is made of high density polyethylene (HDPE) or of glass reinforced nylon, a small notch may easily be cut into it to allow theobstruction 10 to be mounted on the lowermost course ofrails 203 across one of thevertical stanchions 204. Thus, a plurality of such obstructions may be arranged side-by-side and adjacent to each other along the perimeter of the vessel or marine installation by cutting notches into them at positions which correspond to the locations of thevertical stanchions 204. - The
obstruction 10 shown inFigs. 3 ,4 and5 has a height, h, of approximately 300 mm, and the separation, s, between therear surface 142 of thetongue 14 and the centreline X-X' of thelongitudinal groove 12 is approximately 82 mm. These dimensions are sufficient to allow theobstruction 10 to overhang a wide variety of different possible heights of fishplate for different possible distances of theperimeter railing 20 across thedeck 51 to thefishplate 53. In the embodiment of theobstruction 10 shown inFigs. 3 ,4 and5 , the angle, θ, is approximately 103 degrees. -
Figs. 6 and7 respectively show views from an outside or seaward side and from an inside or deck side of an embodiment of aperimeter protection system 100 mounted on aperimeter railing 20 of a vessel or marine installation, such as that shown inFigs. 1 and2 . Theperimeter protection system 100 comprises a plurality ofobstructions Figs. 3 ,4 and5 , and a plurality ofsecurity bulwarks perimeter railing 20 of the vessel or marine installation, above the obstructions. Each of thesecurity bulwarks GB 2 531 232 B perimeter protection system 100 may further comprise one or more of another type of obstruction for positioning in a recess between an adjacent pair of thesecurity bulwarks GB 2 535 681 B - For illustrative purposes only, the vessel or marine installation is shown in
Figs. 6 and7 as having fishplates of two different heights, which are respectively labelled 53a, 53b. This is to show how the orientation of theobstructions obstructions security bulwarks perimeter railing 20 of the vessel or marine installation, above the obstructions. - The plurality of
obstructions security bulwarks perimeter protection system 100 to unauthorized potential boarders and to deter them from approaching the vessel or marine installation. Preferably, they are coloured safety orange. - The vessel or marine installation may further comprise cargo protected by the plurality of
obstructions security bulwarks perimeter protection system 100.
