Definitions

  • the present invention relates to boat lift arrangement for launching and/or recovering of a boat from and into a body of water, which arrangement comprises a cradle structure arranged to support a boat and a lifting structure, which cradle structure and lifting structure together define an open space arranged to place a boat.
  • BACKGROUND ART Arrangements for launching and recovering lifeboats belong to standard equipment on large ships, and various solutions for performing quick release of rescue boats are previously known.
  • US4406244 is presented a launching and recovery apparatus with a cradle from which a boat can hang freely on a releasable support.
  • the base of the cradle comprises roller assemblies that during lowering or hoisting the boat and the cradle run on trackways extending inwardly and upwardly from the deck of the ship.
  • a general problem with many lift arrangements based on winch wires holding the lifeboat is that the wires may do harm to the boat during hoisting or launching.
  • many conventional boat launching arrangements present rigid constructions with hard edges and corners that, especially in heavy sea, may cause damage to the life boat, or indeed people, due to unpredictable movements in connection with launching/recovery.
  • conventional heavy designs lead to that boat launching arrangements often must be provided with a large number of fenders in order to improve buoyancy and seakeeping properties.
  • a boat lift arrangement for launching and/or recovering of a boat from and into a body of water comprising a cradle structure arranged to support a boat, and a lifting structure, which cradle structure and lifting structure together define an open space arranged to hold a boat, wherein said cradle and lifting structure respectively each are formed from flexible members arranged to provide sufficient resiliency to maintain said open space.
  • a boat lift arrangement a lift arrangement or simply an arrangement
  • a small boat such as a rescue boat, a lifeboat or the like
  • a mother vessel or any other fixed installation such as a pier or a platform.
  • the main objects are to provide a boat lift arrangement:
  • the boat to be launched/recovered is a jet driven small boat providing the advantages of having no protruding rotating parts, being relatively light weight and versatile. It is further understood that launching and recovering of said small boat may be done from a floating platform, an oil platform or a harbor pier, although hereinafter "mother vessel” is used.
  • the rescue boat may be stored within the boat lift arrangement on board of the mother vessel until put to use, whereupon the arrangement is preferably connected to conventional davits and lowered into the water so that the rescue boat takes a floating position and can exit by driving forward through the open space as defined by the cradle and lifting structures.
  • a rescue boat to be recovered will enter the open space of a boat lift arrangement positioned in the water next to a mother vessel, where entering is done from behind and into the cradle structure.
  • a particular advantage achieved with a design comprising said flexible members is that it allows for a direct contact between the hull of a boat and the structures of the lift arrangement without such a direct contact damaging the boat. No protective padding, coverage or the like between the hull and the cradle is necessary during storing, launching or recovering of a boat when using an arrangement according to the present invention.
  • the supportive structures comprise flexible frame members, preferably tubular frame members, and preferably which members are resilient.
  • Said tubular frame members constitute the cradle structure as well as the lifting structure.
  • said lifting structure comprises tubular frame members in the form of a pair of lifting bows which, at least during operational mode, extend substantially vertically, upwardly from the cradle structure.
  • the tubular frame members are made out of a plastic material, such as polyethene, contributing to achieve a low weight of the boat lift arrangement but at the same time provide a sufficient rigidity to the structure of the lifting bows and the cradle.
  • said cradle structure has a configuration substantially corresponding to a bottom of a boat meaning it will firmly withhold and support a rescue boat which it displaced therein.
  • the cradle comprises a frontal apex arranged to guide and position the bow of a boat, and also longitudinally extending supporting bar/beam members arranged to position the keel and hull of a boat placed within the cradle structure.
  • the boat lift arrangement comprises at least one connection device in its uppermost portion arranged to be connected to a lifting carabiner held by a cable.
  • the connection device is part of or integrated with the uppermost portion of the lifting bows meaning the lifting bows will be held by the lifting cable which lifts the arrangement when launching or recovering a rescue boat.
  • the cradle comprises at least one detachable buoyant element, such as a fender or pontoon, whereby the seakeeping properties and buoyancy of the lifting arrangement may be adjusted. Fenders also serve for protecting the arrangement from being damaged should it strike against the hull of the mother vessel when being moved downward/upward.
  • the boat lift arrangement comprises a plurality of flexible strap members preferably, but not necessarily, extending alongside with and affixed to the lifting bows. Since being at least partially affixed to the lifting structure the strap members are spread out and form part of said open space which is meant to receive and hold a lifeboat.
  • Each strap member comprises attaching means, for instance in the form of a carabiner, in one end whereby the strap member may be engaged with a lifeboat placed in the cradle. In the opposite end from the attaching means each strap member is connected to the lifting carabiner and the lifting cable with which the boat lift arrangement is hoisted/lowered.
  • said flexible strap members may extend within, and be enclosed by, the tubular flexible members so that the strap members are shielded from outer wear and tear, but still carry and support the arrangement and the boat therein.
  • the strap members may be designed to extend through the tubular members of the lifting structure and further through the tubular members of the cradle structure, forming one or more endless loops that will enclose said open space of the arrangement, and which loops are attached to the upper lifting carabiner in one end.
  • Such a design would lead to an increased safety of the boat lift arrangement since a boat that lies within the cradle will be held not only by the structure per se, but also by the inner strap members.
  • the arrangement may be designed with or without strap members, with strap members extending along the outside of the lifting structure or with strap members extending within the tubular flexible members of the arrangement.
  • the strap members may be made out of synthetic and/or natural fibers, or any other suitable material that provides a sufficient strength according to safety regulation standard.
  • carrying belts, slings or any other kind of well known lifting device instead of strap members.
  • the low weight of the arrangement according to the invention leads to plural additional advantages. For instance transportations will be less costly due to reduced load weight, and the arrangement will be easy to handle both when installing it on a mother ship and when putting it to use for launching or recovering a boat into or out of a body of water. Another significant advantage is that the cradle and lifting structures are essentially self buoyant meaning once the arrangement is released into the water it will be carried in the sea by its own buoyant force. Finally, the low weight minimizes the risk of causing damage when lifting someone/something.

  • Fig. 1 and fig. 2 both show a perspective view of a boat lift arrangement 1 according to two examples of the present invention, where the arrangement 1 in fig. 1 is holding a jet driven rescue boat 6 and the arrangement 1 in fig. 2 is empty.
  • the boat lift arrangement 1 comprises a cradle structure 2, a lifting structure 3 and a number of detachable buoyant elements 4, here in the form of four inflatable fenders arranged around the outer frame 26 of the cradle structure 2.
  • the lifting structure 3 is comprised by a pair of lifting bows 31, 32 where the arms 310, 320 of each bow 31, 32 are fastened to the outer frame 26 of the cradle structure 2 through hinge means 34. As is seen in figs.
  • the cradle structure 2 and the lifting structure 3 together define an open space 7 arranged to receive and place a boat 6.
  • the cradle structure 2 and the lifting structure 3 are both formed from flexible members arranged to provide sufficient resiliency to maintain said open space 7.
  • the flexible members comprise tubular resilient frame members as illustrated by the appended figures, and preferably the tubular frame members are hollow and made out of polyethene or any other type of suitable plastic material with sufficient material strength.
  • the tubular frame members may for instance be manufactured by extrusion and thereafter put together by means of welding to form the desired structures of the cradle of the lifting bows.
  • the boat lift arrangement 1 also comprises a connection device 33 that is affixed to the upper horizontal bars of the lifting bows 31, 32. Said connection device 33 joins the two lifting bows 31, 32 to each other, and connects the boat lift arrangement 1 to a lifting carabiner 8 which in its turn engages a lifting cable (not shown).
  • the arrangement 1 also comprises four strap members 5 extending alongside with and partially affixed to the lifting structure 3.
  • Each strap member 5 comprises attaching means 51 in the form of a carabiner or a snap hook in its lower end which carabiner/snap hook 51 is arranged to be engaged with the rescue boat 6 which lies in the cradle structure 2 of the boat lift arrangement 1.
  • the straps 5 are preferably affixed to the arms 310, 320 of the lifting bows 31, 32 thus extending alongside therewith and essentially forming part of the open space 7 meaning the straps 5 will not get in the way when the rescue boat 6 is to enter or exit the cradle 2.
  • the straps 5 may be attached to the arms 310, 320 of the lifting bows 31, 32 for instance by fastening them with elastic ribbons or springs 52 discontinually along the length of the arms 310, 320.
  • the upper ends of the respective four straps 5 are connected to a lifting carabiner 8 which is attached to a lifting cable (not shown) for hoisting the boat lift arrangement 1.
  • Fig. 3a shows a boat lift arrangement 1 from the back with cradle structure 2, detachable buoyant elements 4, lifting structure 3 in the form of lifting bows 31, 32 joined by a connection device 33 and strap members 5 extending from the lifting carabiner 8 substantially alongside with the lifting bows 31, 32.
  • the strap members 5 are attached to the arms 310, 320 of the lifting structure 3 by a number of elastic ribbons 52, here two ribbons per strap member 5.
  • an attaching mean 51 here in the form of a carabiner 51 , that will engage with the boat once the boat lies within the open space 7 of the lifting arrangement 1. That means if the cradle structure 2 would break when a boat 6 lies within the arrangement 1 the strap members 5 would carry the boat 6 and secure it from falling.
  • the lifting bow 31 at the back of the arrangement 1 is wider than the lifting bow 32 at the front. This means the lifting bows may easily be folded into a more compact unit as is further described in connection to fig. 6.
  • the cradle structure 2 is essentially adapted in shape after the bottom of a boat. It comprises an outer frame 26, at least two U-shaped longitudinal bar members 21 and at least two U-shaped crossing bar members 22. Said crossing and longitudinal bar members 21, 22 respectively are joined to the outer frame 26 of the cradle 2. At the mid back portion of the cradle structure 2 it is seen in fig. 3 that the outer frame 26 is broken forming a gap. Thus a rescue boat 6 will easily enter the cradle 2 during a recovery operation.
  • Fig. 3b is a boat lift arrangement 1 according to another example, shown from the back.
  • This version illustrates an alternative way of arranging the flexible strap members 5 of the present invention.
  • each strap member 5 is tied or somehow connected to the lifting carabiner 8 in an uppermost end, therefrom extending within and through the tubular flexible members 31, 32, 22 of the lifting structure 3 and the cradle structure 2 respectively.
  • the strap members 5 are substantially completely covered by said flexible members thus being protected from outer wear and tear.
  • the strap members 5 extend from the lifting carabiner 8 into the arms 31, 32 of the lifting structure 3 and exit at the lowermost portion of the arms in order to enter the tubular U-shaped member 22 of the cradle 2.
  • connection device 33 is connected to the lifting carabiner 8 independently of the strap members 5 meaning the boat within the cradle 2 is secured both by the flexible members and by the inner strap members 5.
  • Fig. 4 shows a boat lift arrangement 1 from a side view and fig. 5 shows it from above.
  • the lowermost part of the cradle structure 2 preferably comprises a couple of fins 25 attached to the crossing bar members 22.
  • the fins 25 will contribute to keeping the boat lift arrangement 1 on course in the water and stabilize it upon launching a boat.
  • the fins 25 will also reduce the turbulence in the water that would otherwise arise if the mother vessel moves forward during launching. Too much turbulence in the water would substantially lower the capacity of a jet driven motor, meaning a jet driven boat would not be able to easily exit the cradle 2.
  • the existence of the fins 25 solves this problem.
  • the cradle structure 2 is essentially adapted to match the bottom of a boat, and has the purpose of stabilizing and withholding a boat during storing and hoisting/lowering, but at the same time allow for a quick and easy release upon launching. For this reason the cradle structure 2 comprises stabilizing features.
  • a frontal apex 24 of the outer frame 26 of the cradle 2 guides, receives and supports the bow of a boat, and longitudinal bar members 21 have the function of positioning the keel and of guiding the keel when the boat 6 enters the cradle in the water.
  • Figs. 6 and 7 show the boat lift arrangement 1 with lifting structure 3 in a folded position.
  • the connection device 33 is first opened thus detaching the bows from each other.
  • the hinge means 34 which join the lifting bows 31, 32 to outer frame 26 of the cradle structure 2 allow for lifting bows to pivot around said hinge 34. Due to the difference in width each lifting bow may be placed in a substantially horizontal position over the cradle structure thus minimizing the space required by the arrangement 1.
  • the rescue boat 6 is stored within the boat lift arrangement 1 on board of a mother vessel, a platform or any other fixed installation such as a pier.
  • the boat 6 is secured within the cradle by the stabilizing features of the cradle structure 2 as previously described.
  • the boat 6 is also fastened to the strap members 5 by carabiners or snap hooks 51. This means the boat 6 is connected to the lifting carabiner 8 in two ways. In one way through the lifting structure 3 of the arrangement 1 , and in another way through the strap members 5 which are connected to the lifting carabiner 8 independently of the lifting structure 3.
  • the boat 6 would still be carried in said strap members 5.
  • the lifting cable (not shown) that is connected to the lifting carabiner 8 is activated thus lifting the arrangement 1 and the boat 6 that lies therein.
  • Lifting and lowering is done in any conventional way, for instance by use of davits and winches driven by hydraulic accumulators, electric batteries or any other source of energy.
  • the boat 6 within the boat lift arrangement 1 is lowered in a position fairly parallel to the water surface until reaching the sea.
  • the fenders that are arranged around the outer frame 26 of the cradle 2 will protect the structure from hits or strikes during lowering.
  • a frontal painterline (not shown) is extending from the front of the cradle structure 2 to a point at the mother vessel keeping the boat lift arrangement 1 on track during its way down.
  • a person skilled in the art realizes that more than one painterlines may be used during launching/recovering of the arrangement 1, for instance painterlines extending both from the front and from the back portion of the cradle 2 to points at the mother vessel.
  • the operator within the rescue boat releases the carabiners 51 preferably shortly before or immediately after the point when the arrangement 1 and the boat 6 hits the water.
  • the cradle structure 2 When entering the sea the cradle structure 2 will be substantially submerged leaving the rescue boat 6 in a floating position. In order to keep the mother vessel under control it is moving slightly forward at all times which means the lift arrangement 1 will move along with it in the water. Painterlines are preferably also employed when the boat lift arrangement 1 is used from an unmoving pier or platform. The fins 25 of the cradle structure 2 and the painterlines stabilize the arrangement 1 in the sea and keep it in a forward position next to the mother vessel. The fins 25 also reduced turbulence in the water that arise as the mother vessel moves forward. Once the rescue boat 6 has entered the sea it may exit the boat lift arrangement 1 very easy thanks to the new design, e.g.
  • a painterline attached at the back of the cradle structure 2 secures the boat lift arrangement 1 and keeps it from following the boat 6 during its exit.
  • Other solutions, instead of a rear painterline, for keeping the cradle 2 in place in the water during launching of a boat 6 are possible, such as a rear plough anchor that withholds the cradle 2 when the boat exits. Such solution is applicable should the boat lift arrangement 1 be used from a fixed installation like a pier or platform.
  • a boat lift arrangement 1 is lowered into the body of water next to a mother vessel in such a way that the cradle structure 2 is submerged under the surface.
  • Said plurality of fenders 4 will help keeping the cradle structure 2 positioned immediately under the surface and the fins 25 will contribute to stabilizing the arrangement 1 in the water.
  • the rescue boat 6 will then enter the boat lift arrangement 1 from behind and into the open space 7 until it is positioned within the arrangement 1 above the cradle 2 with its bow placed adjacent to the apex 24 of the cradle structure 2.
  • the operator of the rescue boat 6 attaches the plurality of strap members 5 to the rescue boat 6.
  • the arrangement 1 with the rescue boat 6 is winched upwards and back on board to the mother vessel. During hoisting the boat lift arrangement is steered in a controlled manner by painterlines.
  • connection device 33 it is possible to have more than one connection device 33 at the upper portion of the lifting structure 3. Dual connection devices placed at opposite sides of the lifting bows 31, 32 may lead to increase stability during lifting of the arrangement 1. It is also understood that the boat lift arrangement is preferably used for jet driven small boats, but that many of its advantages exist also in connection with other life boats. It is also within the scope of the invention that certain alterations may be done to adapt the cradle for various types of lifeboats.
