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