摘要： Riser system for taking up large amounts of cold seawater from large depth to an intake room in a vessel that in principle lays in a fixed position on the sea surface by spread anchoring or dynamical positioning, which vessel in principle is without rotation with respect to the sea surface, distinguished in that it comprises one single riser having a large flow cross-section, which riser in operation extends from a lower freely hanging end at large depth wherefrom large amounts of cold seawater is taken in through at least one opening and is passed through the riser to an upper end that is located within said intake room, in a suspension that is elastic around a nominal suspension position. The invention results in reduced cooling water demand.
