Abstract

Anordning ved undervannsfarkost for utførelse av arbeid på havbunnen, fortrinnsvis ved store havdyp, slik som for eksempel ved havdyp større enn 200 meter. Undervanns- farkosten er en hydraulisk drevet farkost av i og for seg kjent gravemaskin-type utstyrt med arbeidsredskap, for eksempel graveskuffe, og aggregat for dannelse av hydraulisk drivtrykk til fremdrift av undervannsfarkosten og bevegelse av de armer og ledd som styrer arbeidsredskapet. På undervannsfarkosten er det anbragt en automatisk, trykkregulerende innretning for kompensering av det trykk som vanntrykket ved havbunnen utøver på undervannsfarkostens hydrauliske anlegg. Innretningen består av en stempel/sylinderkonstruksjon, der det omgivende vanntrykk virker mot stempelets bunnside og den hydrauliske oljestrømmen i anlegget er innrettet til å passere gjennom det av vanntrykket varierbare kammer mellom stempelets toppside og sylinderens topp og vegg, og det hydrauliske anleggets pumpe er elektrisk drevet ved krafttilførsel fra styreutstyr som befinner seg over havoverflaten.Device by subsea vessel for carrying out work on the seabed, preferably at large depths, such as at depths greater than 200 meters. The underwater craft is a hydraulically driven craft of a known excavator type equipped with working tools, such as digging bucket, and aggregate for generating hydraulic drive pressure to propel the underwater craft and movement of the arms and joints that control the working tool. An automatic, pressure-regulating device is provided on the subsea vessel to compensate for the pressure exerted by the sea-bed pressure on the subsea hydraulic system. The device consists of a piston / cylinder structure, where the surrounding water pressure acts against the bottom of the piston and the hydraulic oil flow in the plant is arranged to pass through the water-variable chamber between the piston's top side and the cylinder's top and wall, and the hydraulic system pump is electrically driven by power supply from control equipment located above sea level.
