| 摘要 |
The invention relates to an offshore system for transferring fluid at least partly below sea surface. The offshore system comprises a flexible transporting unit and a first movable structure fix-point with a nominal position and a second structure fix-point arranged at a distance to seabed and at a lower position relative to the sea surface than the first structure fix-point. The flexible transporting unit is fixed to respectively the first structure fix-point and the second structure fix-point to provide a catenary liftable length section of the flexible transporting unit extending between the first structure fix-point and the second structure fix-point, wherein the catenary liftable length section has a touch down point at seabed at nominal position and where the distance to the second structure fix-point can be increased sufficiently to lift the catenary liftable length section from the seabed to form a catenary. |
