Abstract

Oppfinnelsen angår en elektrisk drevet undervanns hydraulisk pumpeenhet ( 1 ) for hydraulisk kraftgenerering i et produksjonskontrollsystem, der pumpeenheten ( 1 ) plasseres på en undervannsinstallasjon og knyttes til hydraulikktilførselen ( 10A ) fra overflaten eller et lokalt undervannsreservoar. The invention relates to an electrically driven underwater hydraulic pump unit (1) for hydraulic power generation in a production control system, where the pump unit (1) placed on an underwater installations connected to the hydraulic supply (10A) from the surface or a local subsea reservoir. En pumpes ( 3 ) sugeside med en sugesideakkumulator ( 4A ) koples til hydraulikkfluidtilførselen fra overflaten til en undervanns høytrykksforsterker ( HPI ) på havbunnsinstallasjonen ( 10A ) eller til undervannsreservoaret ( 413 ) av en undervanns hydraulikkraftenhet ( HPU ). A pump (3) suction side with a sugesideakkumulator (4A) connected to the hydraulic fluid supply from the surface to a subsea pressure amplifier (HPI) of the subsea installation (10A) or subsea reservoir (413) of a subsea hydraulic power unit (HPU). Med et kontrollsystem ( 9 ) styres drift av hydraulisk pumpe ( 3 ) med en elektrisk undervanns motor ( 5 ) via magnetkopling ( 6 ). With a control system (9) controls the operation of the hydraulic pump (3) with a submarine electric motor (5) via the magnetic coupling (6). Opplading av en akkumulatormodul ( 2 ) fra pumpeenheten til et høyere fluidtrykk skjer ved bruk av hydraulisk pumpe ( 3 ). Charging an accumulator (2) from the pump unit to a higher fluid pressure is performed using a hydraulic pump (3). Nedjustering av trykket på utgangen av akkumulatorene skjer ved hjelp av regulatorer ( 8 ) til ønsket fluidtrykk for aktivering av ventilsystemer ved stort hydraulikkfluidforbruk. Downward adjustment of the pressure at the output of the accumulators is effected by means of regulators (8) to the desired fluid pressure for actuating valve systems by large hydraulic fluid consumption. Opplading av akkumulatorene skjer med hydraulikkfluidenergi i perioder med tilstrekkelig tilgjengelig elektrisk energi fra strømforsyning til undervanns installasjonen. Charging of the batteries occurs with hydraulic fluid energy during periods of sufficient available electrical energy from the power supply to the underwater installation. Med elektrisk drift elimineres utslipp av hydraulikkvæske til omgivelsene. The motor drive eliminates the discharge of hydraulic fluid to the surroundings.
