Abstract (en)

[origin: WO2021160457A1] The invention relates to an offshore vessel (1, 150) comprising a hull (2, 155) having a length of at least 200m, and having a riser moonpool (17, 170) situated on a longitudinal center line (14) of the vessel extending in a vertical direction from deck level to keel level, the moonpool comprising a riser connector member for attaching risers (27, 76, 76', 77, 77'), to the hull (2, 155). The riser connector member has a riser support structure (26) extending across the moonpool (17, 170) and placed in the moonpool near the bottom (18), for attaching the risers (27, 76, 76', 77, 77') at spaced apart positions distributed over the cross section of the moonpool. A manifold module (68, 69) may be situated alongside the moonpool (17, 170). A pulling system (70, 121, 172) is situated near deck level in an area at or near the moonpool, and comprises a movable lifting member (103, 105, 111) that is displaceable across the moonpool (17, 170) for attaching to the risers (27, 76, 76', 77, 77') and exerting an upward pulling force on the risers. The construction is compact and can accommodate a large number of risers with reduced sagging and fatigue weakening.
