Abstract: A system for supplying cooling water to a process on board a floating vessel for the production of hydrocarbons, wherein the vessel (1) is anchored by means of a bottom-anchored turning unit (20) mounted in a receiving space (7) in the hull (34) of the vessel and allowing turning of the vessel (1) about the turning unit, and wherein the turning unit (20) supports a swivel unit (24) for the transfer of hydrocarbons from production risers (28) extending between the seabed and the turning unit (20), the system comprising a conduit means (30) depending from the vessel (1) to a depth for taking in cooled sea water, and a pump means (44) for pumping of the sea water from the conduit to a place of use for the process. The turning unit (20) is designed as a seawater swivel, the unit being provided with one or more passages (29) for receiving upper end portions of respective seawater risers (30) constituting the conduit means, and with a means for transferring sea water from the upper end portions of the risers (30) to an annulus (31) arranged at the boundary surface between mutually movable parts (21, 22) of the turning unit (20) or between the tuning unit (20) and the vessel hull (34), and communicating with one or more passages (41) arranged in the vessel hull and leading to said place of use, a seawater sealing means (37, 39) being arranged on each side of the annulus (31).

Abstract: Riser system for taking up large amounts of cold seawater from large depth to a turret or similar in a vessel than in principle lays in a fixed position on the sea surface by spread anchoring from the turret or by dynamical positioning, which vessel can rotate freely around the turret while the turret in principle is without rotation with respect to the sea surface. The riser system is distinguished by comprising: a single riser having a large flow cross-section, which riser in operation extends from a lower bottom anchored end at large depth from where large amounts of cold seawater are taken into at least one opening and is passed through the riser to an upper end a little below or in the sea surface; a buoyant body arranged in the upper end of the riser, which buoyant body holds the riser in upright position; one or more flexible pipes arranged from the upper end of the riser to the turret, to pass the cold seawater from the riser to the vessel, with fluid communication through or bypassing the buoyant body. Alternatively the riser is suspended in the turret. The invention results in reduced cooling water demand.
