A sea water intake riser system (100; 100') for a floating production unit (1), comprising at least two caissons (120), wherein the height of each caisson is substantially equal to a vertical height (L) of a hull (5) of the floating production unit (1) and extends, when mounted to the hull (5) of the floating production unit, from a predetermined minimum distance (126) from the bottom side of the hull up to at least the water-line (WL) during use, each caisson (124) comprising an open top side and a through-opening in a bottom side (123); a lift pump (140) arranged inside each of the caissons (120) and having an inlet at a vertical distance (141) with a predetermined minimum submergence (d) and adapted for pumping cold water from the caisson (120) up to the floating production unit (1) for use as cooling medium by production equipment (10) of the floating production unit, and a sump tank (125), attached to the bottom side (123) of each of the caissons such that each through-opening thereof is in fluid communication with a volume inside the sump tank (125), the sump tank being located between the bottom side of the hull and the at least two caissons (120) when mounted and having a through-opening (155) in a bottom side (128) and being connectable to an upper end of a riser pipe (150).

    用于浮式生产单元(1)的海水引入立管系统(100;100')包括:至少两个沉箱(120),其中,每个沉箱的高度基本上等于浮式生产单元(1)的船体(5)的竖直高度(L)并且在使用期间,每个沉箱在安装到浮式生产单元的船体(5)时从与船体的底侧相距预定最小距离(126)处向上延伸到至少吃水线(WL),每个沉箱(124)包括开口的顶侧和底侧(123)中的通孔;提升泵(140),布置在沉箱(120)中的每个的内部并具有在竖直距离(141)处具有预定最小浸没度(d)的入口,并适于将冷水从沉箱(120)泵送至浮式生产单元(1)以用作浮式生产单元的生产设备(10)的冷却介质;以及集水槽(125),附接到沉箱中的每个的底侧(123),使得其每个通孔与所述集水槽(125)内部的容积流体连通,集水槽在安装时位于船体的底侧与至少两个沉箱(120)之间,并且在底侧(128)中具有通孔(155),并且可连接到立管(150)的上端部。
