Abstract
Det er beskrevet en aktuator for å utøve en supplerende kraft til stempelet i en avskjæringsavstenger i en BOP, og en tilsvarende BOP. I en utførelse er en supplerende kraftaktuator (12) beskrevet til bruk på en hydraulisk avstenger (10), idet aktuatoren omfatter et aktuatorhus (30) forbundet den hydrauliske avstengeren; et første og andre kammer (38, 36) som befinner seg i huset, idet kamrene er isolert fra hverandre av et aktuatorstempel (46); en stang forbundet med et stempel (24) i den hydrauliske avstengeren, og passerer gjennom det første kammeret og aktuatorstempelet og rager inn i det minste i et parti av det andre kammeret, idet aktuatorstempelet kan forbindes løsbart med stangen av gripemidler (48), og idet den hydrauliske avstengeren drives av en kraft ved bevegelse av drivstempelet og av en supplerende kraft ved bevegelse av aktuatorstempelet.
