Moistening device of a tanker of unloading of a marine installation of production and storage of products petroleum

摘要

The tanker anchor includes at least two tension anchor lines (10) with their two ends connected together and to the end of the tanker. The other ends are anchored to the sea bed (5) at a distance from each other and from the vertical plane which includes the longitudinal axis of the tanker. Anchoring process for the tanker, by seizing the second buoy and attaching a cable to it Device for anchoring a tanker (6) for discharging a marine installation (1) producing and storing petroleum products, with a link (7) between one end of the tanker and the installation. The device includes at least one buoy (11) fixed at the connected ends of the lines. The length of the lines is such that the buoy stays submersed, holding the lines in a vertical plane by its positive flotation when the lines are waiting, detached from the tanker. A cable is fixed by one end to the buoy, with its other end fixed to a second buoy (15) floating on the surface of the water. A mooring is fixed to the second buoy for attachment of the anchor lines and the cable to the tanker. The anchor lines are metal or plastic cables. Segments of chain connect the anchor lines to their respective anchors (12), with the chain being dimensioned so only these segments lie on the sea bed when the anchor lines are in their waiting position. The device includes a tug connected to the anchored end of the tanker to ensure the security of the loading operation. The installation being discharged is a vessel type FPSO, a fixed marine platform or a floating marine platform.
