Mooring pull-in system
System for anchoring of a vessel, preferably at deep waters, comprising a number of anchoring lines, each anchoring line extending from a fastening means on the vessel to an anchor at the seabed, and the anchoring lines are preferably arranged tightly, obliquely down into the sea around the vessel in the form of spread anchoring, such that the vessel is maintained in a fixed, intended position, distinguished in that each anchoring line is fastened to an anchor and extends out in one length, without joinings, to an upper end where a coupling part is fastened, and the fastening means comprises a crib for each anchoring line, where each coupling part can be laid down in an intended, fastened position. Method for anchoring of a vessel, with use of the system according to the invention.
1. A system for anchoring of a vessel, comprising:
a number of anchoring lines, each anchoring line extending from a fastening means on the vessel to an anchor at the seabed, and
anchoring lines extending obliquely down into the sea around the vessel in the form of spread anchoring, such that the vessel is maintained in a fixed, intended position,
wherein each anchoring line is fastened to an anchor and extends in one length, without joints, to an upper part where a coupling part having a larger diameter then the anchoring line is fastened, and
the fastening means comprises a crib for each anchoring line, having an opening smaller than the coupling part but larger than the anchoring line and wherein each coupling part can be laid down into a dedicated fastened position,
the system comprising a guiding sheave having an adjustable position for guiding and positioning of an anchor line or pulling wire at anchoring line pull in for laying down the coupling part into the crib.
2. The system according to claim 1 , wherein the tension of each anchoring line is 50-100 metric tons.
3. The system according to claim 1 , wherein the anchoring lines are prepared from polyester.
4. The system according to claim 1 , further comprising a swivel arranged at the coupling part.
5. The system according to claim 1 , further comprising a locking means arranged for each crib.
6. The system according to claim 1 , further comprising a fastening means for pull-in wire arranged in each coupling part.
7. The system according to claim 1 , further comprising a means for tightening/adjustment of length of each anchoring line.
8. A method for anchoring of a vessel with use of the system according to claim 1 , wherein
a pull-in wire is extended out from a winch on the vessel and fastened to the coupling part on an anchoring line,
the anchoring line is pulled in with the winch to the coupling part is in position over a crib,
the coupling part is laid down into the crib, and
the operation is repeated for each anchoring line.
9. The method according to claim 8 , further comprising a locking means is mounted on each crib.
10. The method according to claim 8 , further comprising tightening adjustment of length of each anchoring line.
