A vessel (1) adapted to perform subsea wellbore related operations involving a riser string between the subsea wellbore and the vessel, e.g. drilling and/or wellbore intervention. The vessel (1) has a hull (2) and a riser storage (40) adapted to store therein of multiple risers in horizontal orientation. The riser storage (40) is adapted to store therein, or has stored therein, multiple pre-assembled riser stands (60), e.g. at least 25 riser stands, each riser stand being assembled from multiple riser sections (60, 61) connected end-to-end, e.g. each riser stand (62) consisting of two riser sections (60, 61), each riser section comprising a riser pipe and optionally one or more satellite pipes on the outside of and along the riser pipe, each riser section (60, 61) comprising a connector fitting arrangement at each end thereof, and each riser section (60, 61) comprising preferably one or more buoyancy members, wherein in a riser stand the connector fitting arrangement of one riser section is connected to a connector fitting arrangement of another riser section. |
