Abstract

Et hybrid prosesskontrollsystem muliggjør elektrisk overføring av energi til en havbunns hydraulisk energienhet (11), som i sin tur tilveiebringer hydraulisk energi for kontroll av hydrauliske aktuatorer. Et sirkulasjonssystem som anvender rør med liten boring i navlestrengen (3) i kombinasjon med en tradisjonell toppside hydraulisk energienhet (1) tilveiebringer aktiv kontroll av hydraulisk fluidkvalitet i forbindelse med forurensning bevirket av de havbunns hydrauliske aktuatorer, spesielt prosessgass fra nedhulls sikkerhetsventiler. En mer økonomisk energioverføring oppnås således uten reduksjon av fluidkvalitet, som er essensiell for systemintegritet og pålitelighet. En signifikant forbedring av energioverføring uten en dramatisk økning i størrelsen av hydrauliske tilførsels- og returledninger oppnås også. Fluidmiljøspørsmål reduseres til et neglisjerbart aspekt.
