    Abstract: 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.
