摘要 |
A multi purpose hoisting device for use on a floating vessel having a deck, including: a load bearing structure to be mounted on the vessel; a main hoisting mechanism for raising/lowering an object above the deck and including: at least one main hoisting winch; an upper cable pulley block supported by the load bearing structure; a travelling cable pulley block; a main hoisting cable associated with the at least one main hoisting winch and passed over pulleys of the upper cable pulley block and of the travelling pulley block in a multiple fall configuration, such that the travelling cable pulley block is moveable relative to the load bearing structure by using the at least one main hoisting winch; a main hoist heave compensation mechanism associated with the main hoisting cable for damping the effect of sea-state induced motion of the vessel onto an object supported by the main hoisting cable. |
