Abstract (en)
[origin: WO2013087387A1] The invention relates to a water lifting system, in particular a fire extinguishing system for offshore installations, such as oil and/or gas production platforms or ships or the like, comprising a pump (3) having a suction opening and an output opening, a pump-turbine assembly (6) having a pump unit (4) and a turbine unit (5), wherein the pump unit (4) and the turbine unit (5) each have a suction or input opening and an output opening, and a line (7) connecting the output opening of the pump unit (4) of the pump-turbine assembly and the suction opening of the pump (3) and conducting a volume flow (QS). According to the invention, the volume flow (QS) comprises a first partial volume flow (QF) and a second partial volume flow (QT), wherein a line (10) conducting the first partial volume flow (QF) is connected to at least one water extraction point and a line (11) conducting the second partial volume flow (QT) is connected to the input opening of the turbine unit (5) of the pump-turbine assembly (6). The invention further relates to a method having such a system.
