International Classification:

B63B 39/00
B63B 21/00

US Classification:

114122, 1142301, 114231

Abstract:

A vertical damping system for a plurality of water vessels for diminishing the relative vertical movement between two or more water vessels moored in a skin-to-skin orientation. The vertical damping system may include one or more vertical damping devices, each device pivotally connected to a side portion of a first vessel and detachably connecting to a side portion of a second vessel. The vertical damping device may be a piston/cylinder arrangement and the damping system may involve more than two water vessels. The vertical damping system counteracts the effect of roll motion on water vessels, thereby enabling ship-to-ship functions such as cargo loading and the like.

International Classification:

B63B 35/40

US Classification:

114258, 114259

Abstract:

A method and apparatus for cargo transfer at sea, more particularly, a flow-through vessel and related method for the at-sea and underway launching and loading of air-cushion vehicles. The vessel includes a hull having a forward end and an aft end, a continuous deck extending from the forward end to the aft end of the hull, a forward ramp attached to the continuous deck at the forward end of the hull, and an aft ramp attached to the continuous deck at the aft end of the hull. At least a portion of the continuous deck is uncovered and accessible from above the deck.

International Classification:

B63B 17/00

US Classification:

14 695, 114362

Abstract:

As typically embodied, the inventive ramp system for bridging between structures (e. g. , marine vessels) includes a hydraulic elevator device and a ramp unit. The ramp unit includes three adjoining planar members, the ramp member (the main ramp body) being pivotably connected at each end to one of the two platform members. The hydraulic elevator device includes the coaxial combination of a cylinder and a piston, the piston being translatable along and pivotable about the axis. The cylinder-piston combination is secured, axis vertical, to a first structure, with one of the ramp unit's platform members attached atop the piston. In order to position the other (unattached) platform member upon a selected (e. g. , horizontal) location of a second structure, the ramp unit is configurable in terms of the attached platform member's height, the ramp unit's horizontal rotation angle, and the respective vertical rotation angles of the ramp unit's two pivotable connections.
