Offshore crane tower system.

摘要

An offshore crane tower system for use on a vessel with a moonpool includes a tower structure which extends in a vertical direction and is for placement on the vessel adjacent to and/or above the moonpool; a crane with a hoist system able to lift and lower a load; and a crane support at an upper portion of the tower structure. The crane can selectively connect to the crane support so that the hoist system of the crane can be used to lift and lower a load through the moonpool.
