    摘要: It is described a submersible pump system for pumping upwards water being used by a wind turbine, in particular seawater (2002) being used by an offshore wind turbine. The submersible pump system comprises (a) a submersible pump (101) having a pump inlet (102) and a pump outlet (103); (b) a riser pipe (104) for transporting upwards the water (2002), wherein the submersible pump (101) is accommodated within a bottom section of the riser pipe (104); and (c) a wireline (109) with a first end and a second end, the first end being connected to the submersible pump (101) and the second end being connectable to a lifting system (110); wherein the riser pipe (104) and the submersible pump (101) are dimensioned such that with the help of the wireline (109) the submersible pump (101) can be moved within the riser pipe (104) upwards and downwards. It is further described a method for pumping upwards water being used by a wind turbine (1000) and a wind turbine with such a submersible pump system.

    摘要: A vortex-induced vibration (VIV) strake arrangement is provided. The VIV strake arrangement comprises: a VIV strake shell for location on a conduit; and a VIV strake fin, for coupling to the VIV strake shell, comprising a flexible fin tip, a flexible first leg extending from the flexible fin tip and a flexible second leg extending from the flexible fin tip, wherein the VIV strake fin is shaped such that when the VIV strake fin is connected to the VIV strake shell and the VIV strake shell is located on the conduit, the flexible first and second legs extend from the flexible fin tip and define a void between the flexible first and second legs.
