Abstract: A subsea equipment operations arrangement for an offshore platform or vessel includes a working deck with an opening to allow passage of subsea operation equipment to and from a position below the working deck, a lifting structure positioned above the opening to lift and handle heavy subsea operation equipment through the opening, and a system for transporting the heavy equipment laterally over the working deck to and from the opening. The system includes a rail structure on the working deck that supports and guides a movable carrier configured to carry the heavy equipment. The opening extends in a lateral direction from a lifting position below the lifting structure to a point aside the lifting position. A first deck section is movably arranged in the opening, covers a portion of the opening, and includes rail members.

Abstract: Device (10) or apparatus for launching at least one boat (12) from a structure (14), that is at least partially surrounded by water (16), into the water. The device (10) comprises at least one launch ramp (18) and means to effect translational displacement of said at least one launch ramp (18) when the device (10) has been mounted on said structure (14) in order to enable the position of said at least one launch ramp (18) to be changed before launching said at least one boat (12) into the water (16).
