Abstract: The invention relates to a davit arrangement (1, 20) arranged suspended over one or more boats or cargo devices (B, C) onboard a ship or similar vessel for launching or storing the one or more boats or cargo devices (B, C), the davit arrangement (1, 20) comprises a davit housing (19) having telescopically displaceable davit arm (3, 4, 5) and a hoisting arrangement (6) for hoisting and lowering the one or more boats or cargo device (B, C). The davit arrangement comprises a carrier (2) slidable connected to the davit arm (3, 4, 5), the hoisting arrangement (6) being further connected to the carrier (2), the davit housing (19) is connected to a turntable (10) for rotational movement of the davit arrangement (1, 20) around a center axis (A), the carrier (2) is adapted to be retracted to an innermost position where the hoisting arrangement (6) is aligned with the center axis (A) of the turntable (10).

Abstract: A davit arrangement for launching and storing one or more boats or cargo devices, comprising —a carrier construction (1, 2) slidingly connected to a rail construction (3), said rail construction (3) is adapted to be fixedly attached to a roof or other overhanging construction (9), —a davit arm (6) arranged slidingly connected to the carrier construction (1, 2), said davit arm (6) is adapted to move between a launching position where the davit arrangement is adapted to hoist the boat or cargo device (A, B) to or from the sea surface, and an intermediate position where the boat is retracted into a position within the carrier construction (1, 2) of the davit arrangement, —a cylinder arrangement (4) is connected to the carrier construction (1, 2) at a point (4a) and connected to the rail construction (3) at an end (4b), said cylinder arrangement (4) is adapted to move the carrier construction (1, 2) between the intermediate position and a storage position where the boat or cargo device (A, B) is adapted to be sto

Abstract: An apparatus for launching, stowing and retrieving of daughter boats (1) from a midships hangar or mission bay on a mother vessel comprises at least one davit assembly positioned atop a stationary cradle (2), located one each near the starboard and port of the mother vessel. The daughter boats (1) are secured on specially designed stationary cradlesalong a plurality of longitudinal tracks (5) and also on at least the two stationary cradles (2) one each near the starboard and port of the mother vessel which are also specially designed and lie along at least one transverse track (6).

Abstract: An apparatus (1) for handling daughter boats (2) on a mother vessel comprising one davit assembly positioned atop a stationary cradle (5), each of which is located near a side edge (11a, 11b) of a deck (11) of the vessel for launching and retrieving the boats (2) from and onto the stationary cradle (5) characterised in that the apparatus has a plurality of longitudinally movable cradles (7) on the deck (11) of the vessel for securedly holding plurality of boats thereon and in that the longitudinally movable cradles can move back and forth longitudinally and lift up vertically to transfer a boat (2) onto or to receive a boat (2) from, one transversely movable cradle (4) which can transversely move back and forth for placing a boat (2) onto or for receiving a boat (2) from, the longitudinal cradles (7) and any one stationary cradle (5). The invention also relates to a method for launching and retrieving boats from a mother vessel.

Abstract: A davit device (20) is arranged suspended over an associated boat (123) onboard a ship (25) or similar vessel. Horizontally, telescopically displaceable davit arms (121, 121) can move the boat (123) from a parking position to a launching position, and vice versa, while a hoisting device (122) can move the boat (23, 123) vertically. In that the hoisting device (122) is secure to the radially innermost, axially extendable telescope part (121a, 121a) of the davit arms (121,121), the vertical and horizontal movements can be carried out independently, in a controlled way.

Abstract: The hydraulic system is used to drive a hydraulic motor for operation in a quartering direction for lowering of cargo as well as for operating the drive motor in a lifting direction. The hydraulic system employs an oil-gas accumulator which accumulates pressure oil during a quartering mode of operation of the drive motor. During a subsequent lifting mode of operation of the drive motor, stored pressure oil is used for the operation of the drive motor.
