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 5):
The vessel according to  claim 1 , wherein the vessel is provided with a first set of pivotal hatches, said first set of pivotal hatches being arranged along one of said longitudinal sides of said riser transfer opening, and wherein the vessel is provided with a second set of pivotal hatches, said second set of pivotal hatches being arranged along said other one of said longitudinal sides of said riser transfer opening, so that with said pivotal hatches in a horizontal position thereof said riser transfer opening is closed and with said hatches in an upward pivoted position thereof said riser transfer opening is open, and wherein, in said upward pivoted position thereof, said pivotal hatches are to the outside of the horizontal rails at a spacing that allows for travel of the catwalk machine frame over said horizontal rails between said upwardly pivoted hatches.
