Method and apparatus for tensioning anchor lines
Patent
·
OSTI ID:6507733
A method and apparatus for tensioning anchor lines connecting a marine structure to the ocean floor. The apparatus includes a platform movable in relation to the structure, and suspended from the structure by a pulley system with a cable having a free end connected to a vessel. The cable is pulled either by moving the vessel along a rectilinear path passing essentially through the center of the structure, or by a pulling system on the vessel. Diametrically opposed pairs of anchor lines are hooked under the movable platform, each line passing through the groove of a pulley and then through a stopper device fixed to the marine structure. The method and apparatus are particularly adapted for anchoring an emerging structure built on a jointed column.
