METHOD AND SYSTEM FOR THE CASTING OF ANCHORS AND MOORING OF PLATFORMS, AND ANCHOR CASTING UNIT FOR SAME

摘要

The present invention relates to an anchor casting system for anchoring offshore drilling and oil tanker platforms using anchor lowering craft, and the general structure of the anchor casting system is a deck having a lifting passage of an anchor, a chain operating capstan, a wire rope drum. It consists of a chain loading rocker installed under the deck and reciprocating the chain to the capstan by an anchor pipe and a cable winding drum mounted on the pedestal. When anchoring the platform, after securing each platform chain to the anchoring line already placed, use the lowering device and the anchoring line lifting device to prevent the anchoring line from slipping or deviating when lowering the anchoring line to the position of its deflection.
