Abstract: A survival craft comprises a hull (10) formed from inflatable members (12, 13) and mounting a powered propulsion system (18, 19) for the survival craft. A superstructure (11) is mounted on the hull and formed from inflatable members (25, 26, 29a-29i) and a flexible roof (28) supported by the inflatable members (25, 26, 29a-29i). The superstructure provides the hull (10) with increased longitudinal rigidity that reduces the tendency of the hull (10) to bow longitudinally when the propulsion system (18, 19) is operating. The survival craft forms part of a marine escape system with the survival craft deflated and packed in a container including an inflation system for the survival craft. The system has a deployment system for amounting on a marine structure and carrying the container with the deployment system transferring the container from the structure to the water where the inflation system inflates the survival craft for access by persons.

Abstract: A lifter assembly includes a base having a top and a bottom surface. Connectors are attached to the base extending outwardly from the bottom surface. Each of the connectors includes at least one rail wheel rotatably attached thereto. The base includes traveling wheels rotatably attached thereto. A post is attached to the base extending outwardly from the top surface to a distal end. An arm is disposed on the distal end, rotatably attached to the post, extending outwardly to a terminal end. A support is movably attached to the arm and extends outwardly to a support end. A trolley is slidably disposed on the arm and movable along the arm between the terminal end and the post. Each of the traveling wheels includes a leg pivotably attached to the base connecting the traveling wheel to the base and move the traveling wheel between a transport and a storage position.

Abstract: This disclosure provides a system and method for limiting a swing angle of a jib crane, the jib crane having a jib rotatably mounted to a mast. The device can have a collar having a collar height and a collar width, the collar being configured to be fit to the mast at a stop height. The device can also have one or more stopping tabs enagagable with the collar and configured to be positioned on the collar at one or more points about a circumference of the mast. The stop height can place the one or more stopping tabs in a position coincident with the jib to interfere with the swing angle of the jib. The method can use the device to limit the angle through which the jibe crane can swing unimpeded.

Abstract: An onboard davit assembly for launching a boat from a ship is disclosed. In at least one embodiment, the assembly includes two spaced apart davits, each davit including a substantially horizontal boom, a hoist cable extending downwards from a suspension frame on the boom and including at least one fixation device at its lower end to which the boat can be attached. In at least one embodiment, the assembly is arranged such that the booms are movable between an inward position wherein the suspension frames extend inboard and an outward position wherein the suspension frames extend outboard, wherein the booms extend from an onboard vertical pivot axis and can rotate in a horizontal plane around the pivot axis, and wherein the suspension frames are movable along the booms such that a distance between the suspension frames remains constant during rotation of the booms between the two positions when the boat is moved from a parking position to a launching position.

Abstract: The rotating davit apparatus is for fit next to a boat arch. The apparatus is also provided with a modified arch, as desired by the customer. The apparatus is designed to blend into the shape of boat arches, and is thus provided in a plurality of sizes and lift arm angle variations. The apparatus can be used singularly or in pairs, triplet, or as a quad installation wherein 4 apparatuses are mated to the arch. The apparatus provides utility as well as aesthetic appeal. The basic design provides for relatively inexpensive production and sale.

Abstract: Crane for a towing suction device of a dredging craft, which crane is provided with a carrying arm with which a movable tube part of the towing suction device can be displaced between an inboard non-operative or rest position and an outboard dredging position, with which at least one power driven winch is arranged for hoisting and/or paying out one or more cables connected with the movable tube part, the winch with its motor being housed inside a closed tube shaped part of the carrying arm, said winch motor being placed coaxially at the inside of the winch, whereas the winch cables also extend at least partly through the tube shaped carrying arm.
