Abstract:
An offshore drilling vessel includes a floating hull subjected to heave motion. The hull includes a moonpool and a drilling tower near the moonpool. A drilling tubulars storage rack is provided for storage of drilling tubulars. The vessel includes a heave motion compensation support that is adapted to support a slip device whilst performing heave compensation motion relative to the heaving motion of the vessel. A racking device is provided with a heave motion synchronization system that is adapted to bring a tubular retrieved from the storage rack in heave motion into a vertical motion that is synchronous with the heave compensation motion of the string slip device. The racking device includes vertical rails and at least two separate motion arm assemblies mounted on said vertical rails. Each separate motion arm assembly includes its own vertical drive which is electrically connected to the heave motion synchronization system.

Claim (Index 15):
The vessel according to  claim 1 , wherein the vessel comprises:\n a drill string main hoisting device comprising:\n a main hoisting winch and main cable connected to said winch; and \n a travelling block suspended from said main cable, which travelling block is adapted to suspend a drill string therefrom along a drilling firing line, with an intermediate topdrive adapted to provide a rotary drive for the drill string; and \n a drill string heave compensation system adapted to provide heave compensation of the drill string.
