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.An anchorage system for anchoring tankers or a production vessel at a marine oil production site includes a plurality of anchor cables, such as four anchor cables (1,2,3,4) each having a seabed anchor at its distal end, an anchor cable assembly unit (5) through which at least one of the anchor cables (2, 3) runs, and to which each of the other anchor cables (1,4) is attached at its respective proximal end. Furthermore, the system includes a swivel unit (6) to which the proximal end of each movable anchor cable (2, 3) is attached, and a submerged buoyancy device (7) also associated with the swivel unit (6). Each of the movable anchor cables (2, 3) has a stop (12) for limiting the movement of the assembly unit (5) along the cable in a direction towards its distal end. A mooring cable (8) is also attached to the swivel unit (6), and a marking line (9), which has surface marking buoys (56) for locating and retrieving the mooring, is attached to the mooring cable. In a loading or production system, at least one ladder line (10) is connected to the fluid connection swivel unit (6) through the swivel unit to a respective continuing load line (11) which goes to the anchored vessel.
