FIELD: oil and gas producing industries.
SUBSTANCE: invention relates to underwater pumping sets (stations) for transfer of multicomponent gas-liquid mixtures and it can be used for pumping multicomponent products of sea wells with high and unstable gas content. In proposed underwater pumping station containing at least one screw pump installed on pipe whose inlet is connected with liquefaction main line through electromagnetic valve electrically coupled through control unit with thermocouple installed at pump outlet, liquefaction main line communicates with sea water surrounding the station.
EFFECT: provision of restoration of pump efficiency and elimination of overheating.
