FIELD: engines and pumps.
SUBSTANCE: group of inventions relates to systems and methods for increasing fluid pressure in the hydrocarbon gas separator - the liquid located on the sea bed. The system comprises a separator with upper and lower sections connected in fluid medium with at least one pipe extending from the lower section to the upper section; the first pump set into the separator lower section and made with possibility to increase the fluid pressure level in the lower section when the separator is on the seabed; and the upper section connected with the separator and made with possibility to connect the liquid outlet pipe located at least partially outside the separator with the first pump.
EFFECT: invention increases liquid pressure in the separator to the required level.
