Definitions
- This invention relates to a lifeboat system comprising a lifeboat and davits for lowering the lifeboat to the sea surface.
- rafts During evacuation of vessels due to average or fire, lifeboats or rafts are used.
- the most essential advantages of rafts are that they are of little weight and occupy little space during transport and in a ready state.
- Rafts are inflated by means of integrated containers of CO 2 when a desire arises to use them, or automatically by means of a sensoric release mechanism reacting on pressure or water.
- One of the disadvantages of rafts is that they have no propulsion engine or steering capability. Further they give very limited protection against water and cold and they easily capsize, particularly in strong wind combined with waves.
- Hardtop-covered and so-called partially hardtop-covered lifeboats give a better protection for the passengers and are futhermore capable of being manouvered by means of their own engine. It is necessary to have lifeboats and/or rafts having room for all the passengers and the crew of a vessel.
- the International Maritime Organization (IMO)-standard requires that passenger ship lifeboats shall be partially covered. The cover serves as protection from wind, precipitation, cold or heat, sunrays, splashing from waves, and water filling.
- free-fall-lifeboats are used more and more.
- Such systems require special standards of instruction and physical capability of those who shall use the system. Further, free-fall systems require much space, measured relative to conventional lifeboat systems. This makes use of free-fall systems less relevant for passenger ships.
- lifeboats on a lifeboat deck in the way presently done on modern passenger ships with ordinary davits (see Fig. 1b) requires much space.
- Most lifeboat systems comprising lifeboat and davits in their assembled state raised between 4 and 6 metres from the lifeboat deck. This is due to the lifeboat's own height from the keel to the pilothouse, altogether usually more than 2.5 metres, and also as the lifeboats are held at least two metres above the deck in order for unhindered passage for passengers below the lifeboat keel.
- the launching arrangement requires much space for storage and launching.
- the lifeboat "steals" valuable deck area and space volume of the ship. Further the lifeboats hinder free outlook from cabins and living-rooms on the concerned decks. On board some fast and running passenger vessels only inflatable and more protecting lifeboats are used. This is due to existing lifeboat systems weight and space requirements which is incompatible with the vessels requirement of design, speed and loading capacity.
- Lifeboats are usually exposed to weather and sun and are exposed to deposits of salt, sand and dust. Normally this will entail maintenance such as cleaning of the lifeboats, repeated greasing of wires, sheaves, pulleys and blocks; washing or sandblowing and painting of davits. All sea spray in hot climate entails rapid evaporation and leaves considerable amounts of salt at every surface. Such maintenance in the present open systems is work-intensive and expensive.
- An example of modular lifeboat systems is found in GB2229402 "Self-launching accomodation modules in off-shore environments" describing a living quarter module being releasable and which can be launched as a covered lifeboat.
- the module is in the shape of a living quarter giving complete living, cooking and mess localities for the crew.
- the module is arranged on a carrier frame arranged for vertical displacement on vertically arranged guide rails on the ship's side so that the module in normal use is situated above the deck, usually on the outside of the platform or the vessel. In an emergency situation the guide frame with the module is guided downwards in order for the module to reach the sea.
- the module contains propulsion means so that it can move away from the possibly averaging vessel or platform.
- the module requires much space and a system comprising an outboard support frame and vertical guide rails.
- Another GB2108054 "Method and apparatus for rescuing the crew of a ship or a sea platform" describing a lifeboat station with a lifeboat with an ejection mechanism from a closed lifeboat storage room under a deck and below the waterline of the mother vessel. This may be an advantage if an oil fire takes place at the sea surface.
- the lifeboat is arranged in a frame which is arranged to push the lifeboat out through a hatch in the ship's side after the lifeboat has been closed and the storage room has been filled with water. Admittance to the lifeboat takes place through a hatch from the deck above the lifeboat storage room.
- the disadvantages by the lifeboat system illustrated in GB 2 108 054 is among others that if the ejection mechanism should fail then there is no way to return after the lifeboat storage room has been filled with water.
- the hatch in the ship's side may be damaged and thus impossible to open so that the lifeboat is not able to be entirely released. If the ejection mechanism does not guide the lifeboat entirely out of the lifeboat storage room and the vessel has a low heel towards the side where the acual lifeboat is situated, it may be difficult to get the lifeboat away from the averaging mother ship.
- GB 2 186 547 “Ship davit system” describing a device for taking cargo onto a vessel, and lowering the cargo, with a deck partially consisting of a roof-shaped upper deck extending in the entire breadth of the ship, and being integrated in the main structure of the ship, with two separate guiding frames extending in the entire breadth of the ship in the upper deck or by the stern edge of the upper deck, with a davit movably arranged on sheaves in the main frame.
- These davits are arranged to be extended straightly out from the vessel's side through the side of the upper deck.
- the lightboat described in the the GB-publication is an open lightboat, and not a covered lifeboat.
- the davits in the GB-publication is arranged in a fixedly arranged guiding frame in an overlying ship deck, and the lightboat is placed standing on an open lower deck, and not arranged in a lifeboat storage room.
- the separate guiding frames for the davits are arranged above the lightboat's position in its ready-for-use attitude on deck.
- the guiding frames constitute a fixed built-in part of the overlying deck and constitutes no part of an integrated lifeboat system. Thus the guiding frames are not possible to replace.
- the davits are arranged for independent operation outwards and inwards with respect to each other. Each davit may be used as a crane for loading and unloading. This implies that the davits of the GB-application comprise more movable parts and more control devices and are thus vulnerable and complicated to control in an emergency situation.
- a davit system is shown in DE 198 08 491: "Boots-Davit" describing in a German patent publication defines an extendable beam having in its outer end a hinged beam which in turn holds the lifeboat.
- the hinged beam can be locked in the folded-in position with the lifeboat kept in a ready position above the lifeboat deck.
- the lifeboat is brought into boarding position by the ship's side by running the carrier beam outwards and thereafter releasing the hinged beam.
- the lifeboat is not arranged for arrangement in a lifeboat storage room in ready position below a lifeboat deck.
- the davits are also not arranged in the same lifeboat storage room. Boarding of the lifeboat can take place from a balcony in the ready positon or from the deck in an evacuation position.
- DE 198 08 491 constitutes part of the technical art with respect to davits being telescopically extendable in a direction straight outwards from the ship's side.
- one of the problems which gave rise to the invention is to make room for lifeboats having sufficient passenger capacity in a limited space, in a system arranged for simple and safe boarding, and rapid, efficient and safe lowering to the sea surface.
- Another problem which we would like to solve is to gather the entire lifeboat system under the producers' control up to the final assembly of the system comprising a lifeboat, a set of davits and possibly a power accumulator in one assembled and rationally transportable unit comprising each single lifeboat.
- a lifeboat system for a surface vessel comprises a cassette comprising a lifeboat, davits, control/release devices and devices for the davits and lines for lowering the lifeboat to the sea surface, the cassette comprising:
- the opening where the lifeboat is led out of the lifeboat storage room may be arranged in the ship's side with the davits telescoping or in other ways extendable, arranged to be displaced through the ship's side opening, and thereby to keep the lifeboat in an evacuation / boarding position just below and near said lifeboat deck.
- an opening in the lifeboat storage room residing on the underside of the lifeboat storage room, towards an underlying lifeboat deck, has davits arranged to be lowered or rotated down through this opening towards the underlying lifeboat deck.
- the davits are telescopically extendable or in other ways displaceable with respect to the ship's side, and thus arranged to keep the lifeboat in an evacuation/boarding position by the underlying lifeboat deck.
- the invention has advantages among others in that a replaceable cassette may contain the entire lifeboat system.
- the lifeboat system is, as described above, space-saving and gives more design freedom for the ship.
- the lifeboat system according to the invention gives room for more passengers in the lifeboat, and gives space available for more passengers on the mother vessel.
- the lifeboat used according to the invention is easy to board.
- the lifeboat system according to the invention is efficient, energy conserving and gives simpler and safer transport from the lifeboat manufacturer to the outfitting yard and more rapid, safer and simpler mounting in the mother vessel.
- the lifeboat system according to the invention is feasible to evacuate back to the mother vessel if the critical situation is changed or cancelled.
- the lifeboat system according to the invention may be arranged as a closed unit which may be sealed by means of a film and thus reduces the influence of water, salt, sand, and dust and dirt.
- the lifeboat in the lifeboat system will in its ready state storage in the lifeboat storing room be inaccessible without being released. This reduces the possibility of vandalism and theft of regulation required drugs (morphine) and necessary equipment from the lifeboats without being discovered.
- the lifeboat system according to the invention gives better view conditions and overview of the lifeboat deck. Fewer, clean surfaces simplifies cleaning and maintenance of the lifeboat deck.
- the present system is compact and simple, and thus more lifeboats may be arranged in the same volume than by known art, and thus gives improved evacuation safety for more passengers.
- the lifeboat system The lifeboat system.
- Fig. 1 illustrates a part of a simplified cross-section of a vessel, e.g. a passenger vessel with, according to a preferred embodiment of the invention, at least one lifeboat deck 112 which may be covered by a roof or not.
- a lifeboat system according to one of the preferred embodiments of the invention is arranged in a lifeboat storage room 20 arranged immediately below the lifeboat deck 112, directed towards an opening 21, 21' through the ship's side 114.
- the lifeboat system comprises a covered lifeboat 1, davits 4,6, and lines 8 for lowering of the lifeboat 1 to the sea surface.
- Features of the illustrated example of the invention include:
- Fig. 2 illustrates the opening 21 in the vessel's ship side 114 and the davits 4,6 being telescopic or in other way extractable, arranged to be displaced out through the ship's side opening 21, and thus to hold the lifeboat 1 in an evacuation / boarding position just under and near the mentioned lifeboat deck 112.
- a railing 111 is here illustrated as laid down onto the lifeboat deck. In other embodiments of the invention the railing 111 may be dumped in the sea or pushed aside. The railing 111 constitutes no part of the invention, but must be arranged so that under no circumstance it may obstruct the lifeboat system and the opening 21, 21'.
- a hatch 22 in the opening 21 in the ship's side 114 constitutes the outer wall of the lifeboat storage room 20. The hatch 22 is here illustrated turned down about a hinge in its lower edge. It is also possible to arrange the hatch 22 so that it falls into the sea on release of the lifeboat, but this is considered inappropriate, particularly due to an unnecessary loss of material in connection with lifeboat exercises.
- a functional cooperation between the opening 21 and the design of the lifeboat 1 can be arranged so that the outwards facing side of the hull of the lifeboat 1 in its stored position fills the function of the hatch 22, or rather closes the opening 21.
- Fig. 3 illustrates a rigid roof 14 on the collapsible superstructure 12, here with the superstructure in raised position, and with the lifeboat 1 hanging in its upper position on the davits 4, 6.
- Fig. 3 illustrates a rigid roof 14 on the collapsible superstructure 12, here with the superstructure in raised position, and with the lifeboat 1 hanging in its upper position on the davits 4, 6.
- the lifeboat (see Fig. 15) in the lifeboat system there will be arranged with a dosed foldable fabric 16 or wall 16' between the railing 18 of the lifeboat and the roof 14 along the entire railing 18 and the circumference of the roof 14, which in the roof's 14 raised position constitutes the closed outer wall of the superstructure 12.
- Fig. 4 is illustrated that the lifeboat 1 is lowered on the davits 4, 6 via the lines 8 to the sea surface.
- the lifeboat will normally be provided with propulsion means such as a motor and propeller and steering means in the form of a rudder, or propulion means and steering means combined in other form, e.g. a water-jet or similar.
- the propulsion means does not constitute part of the invention.
- Fig. 5 illustrates a situation with negative heel of the relevant side of the mother vessel.
- the present sea regulations say that it shall be possible to launch the lifeboats from a vessel with heel to starboard or port up to 20 degrees.
- there may be two obstacles to launching of the lifeboat 1) the lifeboat 1 and the davits 4, 6 must be displaced "uphill” to get out of the lifeboat storage room 20. 2) the lifeboat runs a risk of hooking to the underlying deck 112' so it either may not pass this deck or it comes into an unstable attitude during lowering.
- the opening 21' in the lifeboat storage room 20 is facing towards or, more correctly expressed, constitutes the lower side of the lifeboat storage room 20, i.e. towards an underlying lifeboat deck 112', and in that the davits 4, 6 are arranged to be lowered or pivotable around an axis 41 down through the opening 21' towards the underlying lifeboat deck 112', as illustrated in Fig. 6.
- the davits 4, 6 is, as explained above, telescopically or in other ways displaceable out relative to the ship's side 114, and thus arranged to hold the lifeboat 1 in an evacuation- or boarding position by the underlying lifeboat deck 112', either in that the davits 4, 6 are turned entirely down to the underlying deck 112' or in that the lines 8 are released sufficiently for the lifeboat railing to end up by the lifeboat deck 112'. Arranged in this manner it is uncomplicated to board the lifeboat 1 from the lifeboat deck 112'.
- the davits 4, 6 of e.g.
- Fig. 7 illustrates the lifeboat deck 112' in a situation with the vessel having a positive heel ⁇ , e.g. between 5 and 8 degrees towards the illustrated ship's side 114.
- the davits and the lifeboat may be telescopingly released directly out through the hatch 22 in the ship's side 114 under the lifeboat deck 112 without the use of any other energy but gravity.
- the lifeboat may thereafter be boarded from two different decks: either from the lifeboat deck 112 or the lifeboat 1 it can be lowered until it is level with the underlying lifeboat deck 112'.
- Fig. 8 illustrates the davits 4, 6 in a fully contracted storage position in a cassette format, as illustrated in section in Fig. 1.
- the hatch 22 and the lifeboat deck 112 has been removed and the ship's side 114 is only indicated.
- a preferrably fork- or U-shaped main frame or a cassette 3 surrounds the lifeboat 10 with collapsed superstructure 12, the davits 4, 6 with lines 8 and control- and release devices 9 for davits 4, 6 and lifeboat 1, and possible power devices 9', arranged for insertion or arrangement of the lifeboat system as an entire unit in an above mentioned lifeboat storage room 20 in a vessel, preferrably via an opening 20, 21'.
- the lifeboat in a prepared boarding position has a considerably larger volume than the lifeboat storage room of which it was taken out from.
- the main frame or cassette 3 is in a preferred embodiment arranged to be pushed nearly like a drawer, horizontally into the lifeboat storage room via the opening 21 in the ship's side 114.
- the height of the entire lifeboat system surrounded by the main frame 3 constitutes typically 1 metre.
- the main frame 3 comprises a preferreably standing horizontal main beam 30 in the (entirely inner) back edge with one horizontal and fixed extending inner fixed telescope part 40, 60 constituting the inner part of each davit 4, 6 in each end of the main beam 30.
- each davit 4, 6 may inthe preferred embodiment comprise a U-shaped frame 5 constituted by an inner longitudinally directed (with respect to the mother vessel) beam 5' connecting the inner ends of the telescoping outer davit beams 41, 61 being arranged to glide from an entirely contracted positon to a maximally allowable extended position along tracks in the inner davit beams 40, 60 as illustrated in Fig. 9.
- the beam 5' In the completely contracted position the beam 5' resides near the main beam 50.
- the winch for lowering of the lifeboat 1 will be arranged at the beam 5 in order to achieve a more simple wire guiding of the lines 8. This will be explained in further detail below. Needed reinforcements in the inner corners against the beams 30 and 5' is a task for the skilled person and only indicated in Fig. 8.
- Fig. 10 illustrates among other things a "telescopic" sliding hoisting block 43 (63) on a hoisting block rail 45 (65) arranged on the telescoping outer davit beam 41 (61).
- the sliding hoisting block 43 (63) can be moved along the hoisting block rail 45 (65) in several ways, but in a preferred embodiment of the invention the displacement of the sliding hoisting block 43 (63) takes place by means of a wire 80 about a sheave 48 (68) arranged at the outer edge of the telescoping outer davit beam 41 (61).
- the displacement of the sliding hoisting block 43 (63) takes place by means of a forced toothed rack- and cogged wheel device 82 arranged between the sliding hoisting block 43 (63) and the telescoping outer davit beam 41 (61).
- the sliding hoisting block 43 (63) may in a preferred embodiment be given a displacement movement which can be guided in and out along the outer davit beam 41 (61) independent of the davit beam's movement.
- the displacement of the sliding hoisting block 43 (63) may be forced, e.g. linearly dependent of the telescoping outer davit beam's 41 (61) movement.
- This forced movement may be provided by means of a toothed rack- and cogged wheel device 82 arranged on a toothed rack 82a on the sliding hoisting block, a toothed rack 82b arranged on the inner davit beam 40 (60), and with a cogged wheel 82c arranged inbetween the toothed racks, and with its axis attached near the inner end of the telescoping outer davit beam 41 (61) near the inner end.
- Fig. 11 illustrates rolls 47 (67) on the inner davit beam's 40 (60) outer end arranged for roll-bearingly supporting the outer davit beam's 41 (61) running displacement out and in from the main frame 3.
- wheels 47' (67') on the outer davit beam's 41 (61) inner end.
- the wheel 47' (67') is arranged to roll along the upper, respectively lower inner surface of a trench 44 in the inner davit beam 40 (60).
- the wheel 47' holds against the lifeboat's 1 and the telescoping davit beam's 41, 61 weight moment in outer position or a partially extended position, and is arranged to carry the lifeboat's 1 and the telescoping davit beam's 41, 61 weight while they are situated in the contracted position.
- the outer telescoping beam 41 (61) is arranged to be drawn out by means of an endless wire 49' fixed in the inner end or rear edge of the beam 41 (61) and with the wire running over a sheave 49 arranged by the outer end of the inner davit beam 40 (60).
- Fig. 12 illustrates the wire sheave / tackle system in the sliding hoisting block 43 (63).
- the lines 8a runs separately via a tackle (with two sheaves) 81a in each sliding hoisting block 43, 63, and via a sheave 81d in a point in the lifeboat 1, e.g. at another boss in the railing, some distance to the opposite side of the lifeboat's centerline with respect to the sheave 81c. In this way it becomes feasible to correct the lifeboat's heel by operating the two wire lines 8a and 8b independently.
- the winch drum 82a, 82b shall be able to winch up the wire 8a, 8b. But if the power supply to the winch drum 82, 82b should fail, it is arranged to be operated as a speed regulated brake with the lowering taking place only by means of braking the gravity force sufficiently.
- the speed regulated brake implies that the lifeboat will become lowered with a speed being essentially independent of the number of passengers in the lifeboat. Details of the winch drum and the braking devices is not concerned in this patent application.
