Abstract:
A vessel adapted to perform subsea wellbore related operations involving a riser string between the subsea wellbore and the vessel. The vessel includes a hull having a deck, and a riser storage hold present within said hull below said deck. The riser storage hold comprising storage racks adapted to store therein parallel stacks of multiple riser sections and/or pre-assembled riser stands in a horizontal orientation. The vessel has an elongated riser transfer opening between said deck and said roof, and the riser transfer opening extending in a direction parallel to said storage racks. The vessel has horizontal rails extending along said opposite longitudinal sides of said riser transfer opening and a catwalk machine having a mobile catwalk machine frame that is movable over said horizontal rails. The catwalk machine is at least in a loading position that is above said riser transfer opening and in a riser upending position.

Claim (Index 7):
The vessel according to  claim 1 , wherein a first overhead travelling beam crane is arranged within the riser storage hold, said first crane being adapted to lift and lower a single riser section or a single riser stand at least allowing for removal of a single riser section or a single riser stand riser stand from a storage rack and for placing a single riser section or a single riser stand into a storage rack respectively, and said first crane being adapted for transverse transportation of a single riser section or a single riser stand at least between said transfer station and a position above a storage rack,\n wherein said first crane comprises: a travelling beam extending in a direction parallel to said storage racks and supported at each end thereof on a crane rail perpendicular to said storage racks, a winch trolley provided with one or more winches and displaceable along said travelling beam, and an elongated gripper frame suspended by one or more winch driven cables from said winch trolley, said gripper frame being provided with multiple riser grippers adapted to engage on a single riser section or a single riser stand at spaced gripping locations thereof, wherein the riser storage hold is provided with first length storage racks adapted to store therein single first length riser sections and/or pre-assembled riser stands, each of said single first length riser sections or of pre-assembled riser stands having a length of at least 100 ft. (30.48 m), wherein the riser storage hold is provided with second length storage racks adapted to store therein single second length riser sections each having a length of between 50 ft. (15.24 meters) and 90 ft. (27.43 meters), and wherein the first overhead travelling beam crane is adapted to transfer a second length riser section between each of said second length storage racks and the transfer station, and to transfer a first length riser section or riser stand between each of said first length storage racks and the transfer station.
