Description

The present invention relates to obstacles for mounting along the perimeter of ships such as commercial ships and warships, or marine facilities such as oil field miners and other marine platforms. The present invention relates to and also relates to a system for protecting the perimeter of a ship or marine facility against unauthorized potential passengers such as pirates, smugglers and activists, and to ship or marine facilities including such a system. Also related to how to protect the surroundings of ships or marine facilities.

With the rise of crime at sea, the need for vessels and marine facilities sailing at sea to be protected against such unauthorized potential passengers has increased accordingly. Unauthorized potential passengers may approach a ship or platform, for example, on one or more small high speed boats equipped with various ladders, climbing poles, grappling hooks and ropes. They lay such boats sideways on larger ships and platforms and lift ladders and climbing poles from the boat onto the sides of the larger ships and platforms to gain access to the decks of the ships and platforms. You may try to board it by climbing the pole. They may also attempt to throw grappling hooks attached to the rope into the deck in order to capture items fixed to the deck and thereby allow them to climb the rope. This has led to the development of several different types of security barriers to protect the perimeter of ships and marine facilities, with the goal of blocking such unauthorized potential passengers. These known security barriers are typically mounted on perimeter rails that extend along the edges of the deck of a ship or marine facility.

On the other hand, many marine and marine facilities further include upright plates that extend along the edges of the deck. Such boards, commonly referred to as fish plates, are on the deck if the movement of the vessel or marine facility causes the deck to deviate from the horizontal, or if the deck is washed by waves or impacted by bad weather. Designed to prevent objects from slipping off the edge of the deck and falling overboard. However, the upper edge of the fish plate may provide a place for unauthorized potential passengers to attach hooks or obtain a grip when attempting to board a vessel or marine facility. .. Fish plates may also interfere with the implementation of security barriers along the surrounding rails. This is especially true if the security barrier extends near or below the bottom edge of the rail to virtually the entire height of the surrounding rails or beyond the edge of the deck towards the sea. apply. Prior art seems to have given little consideration to solutions to these problems.

The present invention is intended to address these and other issues. Also intended is an obstacle to be mounted along the perimeter of the vessel, a perimeter protection system for the vessel or marine facility containing multiple such obstacles, and a vessel containing multiple such obstacles or It is to provide a marine facility and a method of protecting the perimeter of a ship or marine facility that uses multiple such obstacles.

Thus, in the first aspect, the invention provides an obstacle for mounting along the perimeter of a ship or marine facility, where the ship or marine facility is along a deck with perimeter rails and the edges of the deck. Including upright plate. The obstacle has an elongated body that includes a flute for receiving the rails in the lowest row of surrounding rails and a tongue-shaped portion on a plate for projecting outboard, i.e., on the sea side. The tongue-shaped portion includes a posterior surface intended to face inboard when an obstacle is mounted along the perimeter of a ship or marine facility. The separation s between the posterior surface of the tongue-shaped portion and the center line of the flute is 30 to 300 mm, and the separation s between the center line of the flute and the separation s is an angle θ of 90 degrees to 135 degrees with respect to the rear surface of the tongue-shaped portion. Both define the plane that defines the range.

In the case of such obstacles, the fish plate can be protected from unauthorized potential passengers attempting to attach a hook to the fish plate or obtain a grip on the upper edge of the fish plate. The combination of obstacle separation s and angle θ features as described above allows obstacles to cross a wide variety of fish plates of different possible heights and different possible distances across the deck to fish plates. Allows the surrounding rails to be protected in the manner described in great detail below.

Moreover, when using such fish plate protectors as provided by this obstacle, multiple security barriers are placed on the surrounding rails over multiple such obstacles to provide a perimeter protection system for ships or marine facilities. It may be mounted along and requires the adoption of a security barrier that extends substantially across the height of the surrounding rails or extends over the edge of the deck towards the sea near or below the bottom edge of the rail. There is no sex. For example, the security wall extends from the top of the perimeter rail by approximately two-thirds or three-quarters of its height, but may be used instead. Thus, the risk of fish plates that impede the implementation of security barriers along the perimeter rails may be avoided.

Preferably, the tongue-shaped portion of the obstacle has a thickness t that decreases away from the flutes. This helps maintain the orientation of the obstacle with the tongue pointing downwards when using the obstacle. It also has the advantage that the center of gravity of the obstacle shifts more inboard when using the obstacle, reducing the chance of the obstacle being accidentally lost overboard in bad weather or sea conditions.

Preferably, the flutes are adapted to the rotation of obstacles around the rails in the bottom row, so the obstacles can accommodate plates of different heights along the edges of the deck.

Preferably, the obstacle further includes an upper surface intended to face upward when the obstacle is mounted along the perimeter of a ship or marine facility, the upper surface convex in the direction of the depth of the obstacle. It curves like a shape. This has the advantage of ensuring that the top surface maintains a substantially constant height on the deck when the obstacles are rotated to suit different heights of fish plates. Reduces the possibility of interfering with any security barrier mounted on the surrounding rails. It also helps prevent the top surface of the obstacle from being used as a place for a grip by unauthorized potential passengers.

In such cases, the top surface is also preferably substantially smooth. This makes it more difficult for the top surface of the obstacle to be used as a place for a grip by unauthorized potential passengers.

Also preferred for the tongue is to include an anterior intended to face the sea when the obstacle is mounted along the perimeter of the vessel or marine facility, the anterior surface being substantially smooth. be. This makes it more difficult for unauthorized potential passengers to get a grip or scaffolding in front of them.

Preferably, the obstacle further includes mounting equipment proximal to the flutes for mounting the obstacle to the rails in the lowest row. This allows the obstacle to be fixedly fastened to the surrounding rails, even if the obstacle cannot be easily attached to the fish plate.

In such cases, the mounting equipment preferably comprises one or more through holes in the obstacle. This has the advantage of allowing obstacles to be quickly and easily attached to the surrounding rails by tying them together.

Preferably, the obstacle further includes an anti-rotation device to prevent the obstacle from rotating around the rails in the bottom row. This allows an unauthorized potential passenger to flip up the tongue of an obstacle, for example, for the purpose of attempting access to the upper edge of the fish plate to obtain it and to use it as a grip. Has the advantage of blocking.

In such cases, the anti-rotation device preferably comprises one or more through holes in the tongue. This allows the obstacle to be tied, for example, to another adjacent similar obstacle, or to one or more vertical stanchions or support stays on the surrounding rails.

The obstacle preferably has a width w of 0.70 to 1.50 meters, more preferably 0.80 to 1.40 meters, and most preferably 0.99 to 1.30 meters. Such widths have the advantage of being optimally fitted to the space between adjacent vertical struts of the perimeter rails commonly encountered.

Preferably, the tongue has a height h of 200-600 mm, more preferably 250-500 mm, most preferably 300-400 mm. Such height has the advantage of being optimal for different possible distances of the surrounding rails from the fish plate across the decks that are normally encountered.

Preferably, the obstacle is composed of one or more materials that are resistant to weather and seawater, such as an inert plastic material. For example, obstacles may be made of high density polyethylene (HDPE) and / or glass tempered nylon, both of which also have good strength and stiffness.

In a second aspect, the invention includes a plurality of obstacles according to the first aspect of the invention and a plurality of security barriers for mounting on the perimeter rails of a ship or marine facility on the obstacles. , Also provides a perimeter protection system. The security barrier may be of the type illustrated and described, for example, in British Patent GB2531232B, also in the name of the Applicant, the contents of which are incorporated herein by reference.

In a third aspect, the present invention relates to a plurality of obstacles arranged side by side along the perimeter of a ship or marine facility and adjacent to each other, and on the obstacles, according to the first aspect of the present invention. Further provided for a ship or marine facility, including a plurality of security barriers arranged side by side along the perimeter rail of the ship or marine facility and adjacent to each other. Thus, the perimeter of a vessel or marine facility can be protected by multiple such obstacles and multiple such security barriers that interact with each other, leaving both the perimeter rails and fish plates to unauthorized potential passengers. Protect against.

Vessels or marine facilities may further contain cargo protected by multiple obstacles and multiple security barriers.

In a fourth aspect, the invention also provides a method of protecting the perimeter of a ship or marine facility, the ship or marine facility comprising a deck with perimeter rails and an upright plate along the edge of the deck. The method is to position a plurality of obstacles according to the first aspect of the present invention side by side along the perimeter of a ship or marine facility and adjacent to each other, and to position the rails in the lowest row of the perimeter rails as obstacles. Includes acceptance in the flutes of the obstacle and hanging the tongue of the obstacle on its outboard or seaside plate.

Preferably, the method further comprises attaching at least one obstacle to the perimeter rail. This is preferred because it is the easiest. However, in an alternative possible embodiment, the obstacle may be attached in place of another item in the vessel or marine facility, such as an obstacle that is permanently located on the deck, such as a cleat or bit.

In a preferred embodiment, the method also comprises preventing the rotation of at least one obstacle around the rails in the bottom row. This is advantageous because it helps prevent obstacles from being flipped up and exposing the upper edge of the fish plate.

Preferably, the method further comprises positioning multiple security barriers on obstacles side by side along the perimeter rails of a ship or marine facility and adjacent to each other. This is advantageous because both the fish plate and the rail can be subsequently protected against unauthorized potential passengers.

Further features and advantages of the present invention will become apparent from the following detailed description given as an example in connection with the accompanying drawings.

It is a perspective view from the outside of a part of the surrounding rail of a ship or a marine facility, that is, from the sea side. It is a perspective view from the inside of a part of the peripheral rail shown in FIG. 1, that is, from the deck side. It is a first perspective view of the embodiment of an obstacle. It is a second perspective view of the obstacle shown in FIG. It is a side profile view of the obstacle shown in FIGS. 3 and 4. It is a perspective view from the outside, that is, the sea side of the embodiment of the surrounding protection system. It is a perspective view from the inside of the surrounding protection system shown in FIG. 6, that is, from the deck side.

FIGS. 1 and 2 show a view from the outside, that is, the sea side, and a view from the inside, that is, the deck side, respectively, of a typical part of the peripheral rail 20 of a ship or a marine facility. Some of the sides of the ship or marine facility may appear labeled with reference number 52. The peripheral rail 20 includes a plurality of rows of rails, including a handrail 201 at the highest position, rails 202 in the middle row, and rails 203 in the lowest row. There are a plurality of vertical columns 204 at regular intervals along the peripheral rail 20. Regulations require that the vertical stanchions 204 be separated so that they do not exceed 1.5 m. The peripheral rail 20 is mounted on the deck 51 of a ship or marine facility. The total height g of the rail 20 from the deck 51 to the highest handrail 201 is required by regulation to be at least 1 meter. Further, the separation f of the rail 203 in the lowest row from the deck 51 is required to not exceed 230 mm by regulation. The rail 202 in the middle row is positioned approximately equidistantly between the handrail 201 in the uppermost position and the rail 203 in the lowermost row. Thus, the gap between the top handrail 201 and the intermediate row rail 202, or the gap between the intermediate row rail 202 and the lowest row rail 203, is (g-f) /. Given by 2, the thickness of the rail row itself must also be deducted from it. Therefore, each gap usually does not exceed 500 mm in height and is actually much smaller.

Outside the rail 20 at the edge of the deck 51, there is a vertical lip called the fish plate 53, the height of which depends on the type of vessel or marine facility on which the rail 20 is mounted, but is generally about 90 in height. ~ About 400 mm. The distance of the perimeter rail 20 across the deck 51 from the fish plate 53 is not regulated and may therefore vary depending on the type of vessel or marine facility on which the rail 20 is mounted. However, typically, the distance across the deck 51 is up to about 300 mm.

The perimeter rails 20 are supported at regular intervals by a plurality of support stays 205, one of which can be seen in FIG. Regulations require that there must be at least one support stay 205 for every three vertical columns 204, but it is common for there to be a support stay 205 for all other columns 204. Is. Also shown in FIG. 2 is a typical example of an obstacle 23 permanently located inside the rail 20, that is, on the deck side. Such obstacles include accommodation ladders, cleats, and bits.

3, 4 and 5 show when a ship or marine facility includes a deck 51 with perimeter rails 20 and an upright plate 53 along the edges of the deck, such as those shown in FIGS. 1 and 2. , An embodiment of an obstacle 10 suitable for mounting along the perimeter of a ship or marine facility. The obstacle 10 has an elongated body including a vertical groove 12 for receiving the rail 203 in the lowest row of the surrounding rail 20 and a tongue-shaped portion 14 for projecting the plate 53 outboard of the plate, that is, on the sea side. Have. The tongue-shaped portion 14 includes a posterior surface 142 and an anterior surface 144. The rear surface 142 is intended to face the inboard direction of the ship or marine facility when the obstacle 10 is mounted along its perimeter, and the front surface is intended to face the outboard or sea direction. Will be done. Further, the obstacle 10 has an upper surface 16 which is intended to face upward when the obstacle 10 is mounted along the periphery of a ship or a marine facility, and a vertical groove 12 which is opposite to the upper surface 16. The lower surface 18 formed therein is included. The separation s between the posterior surface 142 of the tongue portion 14 and the centerline of the flutes 12 (labeled XX'in FIG. 4) is 30-300 mm. As shown in FIG. 5, the center line XX'of the flute 12 and the separation s both define a plane that defines an angle θ of 90 degrees to 135 degrees with respect to the rear surface 142 of the tongue-shaped portion.

In this way, the obstacle 10 can be arranged such that the rail 203 in the lowest row is received by the flutes 12 and the tongue-shaped portion 14 protrudes on the fish plate 53 outboard, that is, on the sea side. The tongue portion 14 will point downwards, provided that the fish plate 53 is not significantly higher than the separation f of the bottom row rail 203 from the deck 51. Here, "not significantly high" means that the height of the fish plate 53 is not larger than the separation f by more than 30 mm. Thus, in such cases, the upper edge of the fish plate 53 is covered by the tongue-shaped portion 14 to attach a hook to an unauthorized potential passenger when attempting to board a vessel or marine facility or a grip. Can no longer provide a place to get.

On the other hand, when the fish plate 53 is significantly higher than the separation f of the rail 203 in the lowest row from the deck 51, the rail 203 in the lowest row is received by the vertical groove 12 and the tongue-shaped portion 14 is the fish plate 53. If the obstacle 10 were to be rearranged so as to project upwards, the tongue portion 14 would instead point upwards on the outboard or sea side of the fish plate 53. The tongue-shaped portion 14 will then itself provide a possible place for an unauthorized potential passenger to attach a hook or obtain a grip. However, in such cases, there is no need to use the obstacle 10, because the upper edge of the fish plate 53 implements a security barrier along the perimeter rail 20 at a location above the fish plate 53. This would instead make unauthorized potential passengers inaccessible. In such cases, the overhang, i.e., the underside protrusion of the security barrier on the sea side, prevents access to the upper edge of the fish plate 53. Moreover, in such cases, the fish plate itself completely covers the gap between the bottom row rail 203 and the deck 51 because the fish plate 53 is higher than the separation f.

However, in cases where the fish plate 53 is not significantly higher than the separation f, the various different possible distances from the fish plate 53 across the deck 51 of the perimeter rail 20 and the various different possible heights of the fish plate are , The two features of the obstacle 10 mentioned above, namely that the flutes 12 are separated from the posterior surface 142 of the tongue by 30-300 mm and that the angle θ is an obtuse angle of 90-135 degrees. Both are applied by the combination of and. For this combination of features, the obstacle 10 is tongue-shaped with respect to a wide variety of fish plates of different possible heights and perimeter rails 20 of different possible distances from the fish plate 53 across the deck 51. The downward pointing orientation of 14 can be maintained.

The ability of the obstacle 10 to maintain a downward orientation of the tongue portion 14 is another feature of this embodiment of the obstacle 10 (thickness in which the tongue portion 14 decreases away from the flutes 12). It is further promoted by having a t). Thus, when the posterior surface 142 of the tongue-shaped portion adopts an orientation pointing downward, the decreasing thickness t of the tongue-shaped portion 14 means that the front surface 144 points downward at a steeper angle than the rear surface 142. ..

The flutes 12 have a smoothly curved concave profile, as best understood from FIG. Thus, the flutes 12 are adapted to the rotation of the obstacle 10 around the rail 203 in the bottom row, whereby the obstacle 10 facilitates fish plates of different heights along the edges of the deck. Can be accommodated. In contrast, the top surface 16 is convexly curved in the DD'direction at the depth of the obstacle 10. This has two advantages: First, as the obstacle 10 rotates to suit different heights of the fish plate and different separations f of the bottom row rail 203 from the deck 51, the top surface 16 is decked. Ensure that the height from 51 remains substantially constant. Thus, the obstacle 10 is less likely to interfere with the security barrier mounted on the perimeter rail 20. Second, however, it also helps prevent the top surface 16 of the obstacle 10 from being used as a place for a grip by unauthorized potential passengers. For the same reason, both the top surface 16 and the front surface 144 are substantially smooth.

The obstacle 10 further includes mounting equipment 11 proximal to the flutes 12 to allow the obstacle 10 to be secured to the perimeter rail 20. In this particular embodiment, the mounting equipment 11 includes a plurality of through holes 112 formed in the obstacle 10, with the obstacle 10 extending to, for example, the rail 203 in the lowest row and / or one of the peripheral rails 20. Allows it to be tied to one or more vertical struts 204. It may also be associated with an obstacle 23 permanently located on the deck of a ship or marine facility, such as that represented in FIG. However, in a possible alternative embodiment of the obstacle 10, the mounting equipment 11 instead includes, for example, one or more clips for clipping the obstacle 10 to the rail 203 in the lowest row. There is.

Even if the obstacle 10 is fixedly attached to the peripheral rail 20, the rotation of the obstacle 10 around the rail 203 in the lowest row exposes the upper edge of the fish plate 53, which is not desirable. In such cases, an unauthorized potential passenger would, for example, flip up the tongue portion 14 of the obstacle to gain access to the upper edge of the fish plate 53 and use it as a grip. May try. Therefore, the obstacle 10 further includes an anti-rotation device 13 for preventing any such undesired rotation of the obstacle 10 around the rail 203 in the lowest row. In this particular embodiment, the anti-rotation device 13 includes a plurality of through holes 132 formed in the tongue-shaped portion 14. They allow the obstacle 10 to be attached, for example, to another adjacent similar obstacle, or to one or more vertical stanchions 204 or support stays 205. However, in another alternative possible embodiment of the obstacle 10, the anti-rotation device 13 instead has a tongue, a vertical strut 204 or a support stay on the posterior surface 142 of the tongue 14 for engaging with the fish plate 53. It may include one or more arms for engaging the 205, or one or more clips for clipping the obstacle 10 to an adjacent similar obstacle.

In the embodiments shown in FIGS. 3, 4 and 5, the obstacle 10 has a width w of approximately 980 mm. Since the vertical stanchions 204 of the perimeter rail 20 are separated no more than 1.5 meters and are often separated by 1 meter, the obstacle 10 is therefore usually between two adjacent stanchions 204. Can be comfortably adapted to. If the obstacle is made of high density polyethylene (HDPE) or glass tempered nylon, a small notch can easily be cut into it, with the obstacle 10 in the lowest row across one of the vertical columns 204. Allows it to be mounted on rail 203. Thus, a plurality of such obstacles may be placed side by side and adjacent to each other along the perimeter of the vessel or marine facility by cutting a notch in them at a location corresponding to the location of the vertical stanchions 204.

The obstacle 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-shaped portion 14 and the center line XX'of the vertical groove 12 is It is approximately 82 mm. These dimensions allow the obstacle 10 to protrude from a wide variety of different possible heights of the fish plate due to the different possible distances of the perimeter rail 20 beyond the deck 51 to the fish plate 53. Enough to do. In the embodiment of the obstacle 10 shown in FIGS. 3, 4 and 5, the angle θ is approximately 103 degrees.

6 and 7 are views from the outside or sea side and from the inside or deck side of embodiments of the perimeter protection system 100 mounted on the perimeter rail 20 of a ship or marine facility such as those shown in FIGS. 1 and 2. The figures of are shown respectively. The perimeter protection system 100 is to be mounted on a plurality of obstacles 10a, 10b of the types illustrated and described above in connection with FIGS. 3, 4 and 5 and on the perimeter rail 20 of a ship or marine facility above the obstacles. Includes a plurality of security barriers 1a, 1b, 1c and the like. The individual security barriers 1a, 1b, 1c are, for example, of the type illustrated and described in British Patent GB2531232B, also in the name of the Applicant, the contents of which are incorporated herein by reference. Sometimes. Peripheral protection system 100 is illustrated and described in another type of obstacle for positioning in the groove between adjacent pairs of security barriers 1a, 1b, and in UK Pat. No. GB2535681B, also in the name of the Applicant. It may further include one or more of the types (whose contents are incorporated herein by reference).

For purposes of illustration only, the vessel or marine facility is shown in FIGS. 6 and 7 to have two different height fish plates labeled 53a, 53b, respectively. This is to show how the orientation of the obstacles 10a and 10b is adjusted to suit fish plates of different heights. However, in reality, a ship or marine facility usually has a fish plate that is only a single height along the edge of its deck. In practice, since the fish plate has only a single height, multiple obstacles 10a and 10b may be placed side by side along the perimeter of the vessel or marine facility and adjacent to each other. The security barriers 1a, 1b, and 1c are arranged side by side along the perimeter rail 20 of a ship or marine facility and adjacent to each other on an obstacle.

The plurality of obstacles 10a, 10b and the plurality of security barriers 1a, 1b, 1c may be flashy colored, advertising the existence of the perimeter protection system 100 to unauthorized potential passengers. Deter them from approaching ships and marine facilities. They are preferably colored in safe orange.

Ships or marine facilities may further include cargo protected by a plurality of obstacles 10a, 10b and a plurality of security barriers 1a, 1b, 1c of the perimeter protection system 100.
