METHOD AND SYSTEM FOR TENSIONING A FUNCTION LINE, IN PARTICULAR A MOORING LINE, OF AND FPSO-VESSEL OF A FPSO-VESSEL

摘要

A traction method for an operating line, in particular a mooring line, includes the steps of : attaching an end chain portion (6) of the operating line (4) to a socket (33) of a main cable (32) running through a sheave (11) at a work station; reeling in the main cable (32), using a winch (31), to bring the socket (33) of the main cable (32) up to the sheave (11); locking the operating line (4) with a chain stopper (13); slackening the main cable (32) and moving the sheave (11) closer to the chain stopper (13) to reduce pull on the main cable (32); reeling in the main cable (32) to run the socket (33) of the main cable (32) through the sheave (11),- once the socket (33) of the main cable (32) has run through the sheave (11), releasing the operating line (4) from the chain stopper (13), and reeling in, by means of the winch (31), the main cable (32) and the operating line (4) connected to it.
