Smooth brake control system of multiple constant-tension anchor gears for pipe-laying ship

Abstract

The invention discloses a smooth brake control system of multiple constant-tension anchor gears for a pipe-laying ship, comprising a cockpit operation control center and a remote anchor gear engine room control device. The cockpit operation control center is connected to the remote anchor gear engine room control device through an optical cable and used for controlling the multiple anchor gears and collecting traveling state data of the multiple anchor gears. A bow anchor gear control platform and a stern anchor gear operation control platform are in interactive transmission with information of controlling the anchor gear and the operation control center of the engine room cab through a control bus; the control device of the remote anchor gear engine room connects the bow linkage control cabinet, the stern linkage control cabinet to the main control station of a cockpit monitoring center in order to realize the data collection and monitoring of all operation control cabinets in the cockpit. The invention reduces production downtime, realizes smooth braking of multiple anchors, guarantees working state of multiple anchor gears and thus realizes the smooth movement and positioning of the pipe-laying ship.

Description

technical field [0001] The invention relates to a constant tension windlass control system, in particular to a smooth brake control system for multiple constant tension windlasses used in a pipe-laying ship, belonging to the field of offshore oil engineering. Background technique [0002] At present, the maximum pipe-laying depth of a general shallow-water pipe-laying ship is 300m, and its movement and positioning are mainly completed by the braking system of 8-12 windlasses installed on the ship. To determine the moving route and moving speed of the pipe-laying ship. Since the brake systems of each windlass have their own specific purposes, they often perform their own duties during on-site operation, and since the brake systems of each windlass operate independently, when the windlass or pipe-laying ship needs to reach a certain In this working state, the braking process of the windlass braking system will appear unstable. [0003] In order to overcome the above shortcom...

AI Technical Summary

Problems solved by technology

Since the input and output terminals of the controller are far away from the control point, it will be necessary to lay a very long cable, which is not easy to realize

Moreover, the reliability of the control system is reduced due to electromagnetic interference, so that the braking process of each windlass braking system will still appear in an unstable state
