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 1):
A vessel adapted to perform subsea wellbore related operations involving a riser string between the subsea wellbore and the vessel, said vessel comprising:\n a hull having a deck; a riser storage hold present within said hull below said deck, said 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, and said riser storage hold having a floor, side walls, and a roof; an elongated riser transfer opening between said deck and said roof, said riser transfer opening extending in a direction parallel to said storage racks, said riser transfer opening having opposite longitudinal sides, a length, and a width so as to allow for transfer of a single riser section or a single riser stand in horizontal orientation thereof via said riser transfer opening out of and into the riser storage hold; a riser transfer station arranged within said riser storage hold below said riser transfer opening and provided with a transfer elevator that is adapted to raise and lower a single riser section or a single riser stand in said horizontal orientation thereof so as to pass the riser section or the riser stand through the riser transfer opening; 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, and said catwalk machine frame having a rear end and a front end, wherein the catwalk machine frame is movable over said horizontal rails at least in a loading position that is above said riser transfer opening and in a riser upending position; wherein the catwalk machine frame has two parallel and horizontal frame beams; wherein a skate is supported by said frame beams and is configured to travel over said frame beams, wherein said skate comprises a riser end support that is configured to support thereon a rearward end of a riser section or of a riser stand; wherein the catwalk machine frame comprises, in addition to said riser end support, one or more additional riser support members that are each movable between an inactive position and an active position, wherein a riser section or riser stand is supportable on said riser end support and said one or more additional riser support members when in said active position thereof; and wherein the horizontal frame beams of the catwalk machine frame define between them an opening that is dimensioned so that, with said catwalk machine frame in said loading position thereof and with said one or more additional riser support members in said inactive position thereof, a single riser section or a single riser stand in said horizontal orientation thereof is lowerable through said opening between said horizontal frame beams and into said riser transfer opening or is liftable out of said riser transfer opening and through said opening between said horizontal frame beams.
