Abstract
Official abstract text for this publication.
Method for mooring an offshore structure includes: providing a mooring line having one end connected to the sea bed and a connector at a free end; lifting the free end onto a deck of an anchor line handling vessel; connecting on the anchor line handling vessel a chain tensioner with a connection side to the connector; providing a working chain having a short tensioning part and a long installation part into the entry side of the chain tensioner; holding a free end of the installation part while lowering the chain tensioner below water level; picking up a free end of a pendant attached to the offshore structure, and attaching it to the free end of the installation part in an interconnect position on the anchor line handling vessel; placing the interconnect position overboard; connecting a lifting cable on the anchor line handling vessel to the tensioning part below water level; and exerting an upward tensioning force on the tensioning chain part.
