Abstract

Et forankringssystem for oppankring av tankskip eller et produksjonsfartøy på et marint oljeproduksjonssted innbefatter et antall ankerkabler, for eksempel fire ankerkabler (l, 2, 3,4) som hver har et havbunnsanker ved sin distale ende, en ankerkabel-samleenhet (5) hvorigjennom minst en av ankerkablene (2, 3) går, og hvortil hver av de andre ankerkabler (l, 4) er festet ved sin respektive proksimale ende. Videre innbefatter systemet en svivelenhet (6) hvor den proksimale enden av hver bevegelig ankerkabel (2, 3) er festet, og en neddykket oppdriftsinnretning (7) som også er tilknyttet svivelenheten (6). Hver av de bevegelige ankerkabler (2, 3) har en stopper (12) for begrensning av samleenhetens (5) bevegelse langs kabelen i en retning mot dens distale ende. En fortøyningskabel (8) er også tilknyttet svivelenheten (6), og en markeringsline (9), som har overflate-markeringsbøyer (56) for lokalisering og opphenting av fortøyningen, er tilknyttet fortøyningskabelen. I et laste- eller produksjonssystem er minst en stigeledning (10) tilknyttet svivelenheten (6) for fluidumforbindelse gjennom svivelenheten til en respektiv fortsettende lasteledning (11) som går til det oppankrede fartøy.
