Temporary anchor recovery system for ocean platform ship

Abstract

The invention provides a temporary anchor recovery system for an ocean platform ship. The temporary anchor recovery system comprises an anchor rack, a support structure, a chain stop structure, an anchor chain bin, a hinge device and an anchor chain, wherein one end of the anchor rack is horizontally mounted on a bow; the support structure comprises two support arms and a mounting platform; the two support arms are vertically mounted on a main deck of a hull respectively; the mounting platform is horizontally mounted at the front ends of the tops of the two support arms; the support structureis positioned above the rear side of the anchor rack; the chain stop structure is mounted on the mounting platform; a chain inlet is formed in the top of the anchor chain bin, and the anchor chain binis vertically mounted on the main deck of the hull and downward extends to the inside of the hull; the hinge device is mounted at the top of the anchor chain bin and is positioned above the rear sides of the support arms; and the hinge device recovers the anchor chain into the anchor chain bin sequentially through the anchor rack, the chain stop structure, the hinge device and the chain inlet, and an anchor at the end of the anchor chain is clamped on the anchor rack. The temporary anchor recovery system provided by the invention realizes stable and quick release and recovery of the anchor chain on an exposed deck.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a temporary anchor recovery system for offshore platform ships. Background technique [0002] During the process of the offshore platform traveling at sea to the position where it needs to be operated, when it is necessary to temporarily berth in an emergency or unexpected situation, it is necessary to use a temporary anchor chain to locate the ship. And for the recovery system of existing temporary anchor chain, in order to be able to quickly retract the anchor chain, usually an anchor hole is set at the bow position, so that the anchor chain can be recovered into the hull through the anchor hole; but this Although the structure is more convenient for large-scale sailing ships, it is difficult to deal with small-scale platform structures. There are problems such as difficult on-site construction and difficult structure erection. Contents of the invention [0003] The purpose of...
