Multi-point mooring and positioning constant-tension self-adaptive control system and method for ship

Abstract

The invention provides a multi-point mooring and positioning constant-tension self-adaptive control system and method for a ship. The multi-point mooring and positioning constant-tension self-adaptive control system comprises m mooring winches, a detection system and a monitoring station. Each mooring winch is provided with the following detection equipment including an encoder, a tension sensor, a mooring cable angle sensor, a brake position proximity switch, a clutch position proximity switch and a ratchet wheel and pawl position proximity switch, wherein the encoder is used for detecting the length value and the speed value of a mooring cable; the tension sensor is used for detecting the real-time tension value of the mooring cable; the mooring cable angle sensor is used for detecting the vertical angle and the horizontal angle of an anchor cable; the brake position proximity switch is used for detecting the on-off state of a brake; the clutch position proximity switch is used for detecting the on-off state of a clutch; and the ratchet wheel and pawl position proximity switch is used for detecting the on-off state of a ratchet wheel and pawl stopping device. The monitoring station is connected with all servo drivers and all the pieces of detection equipment. The multi-point mooring and positioning constant-tension self-adaptive control system and method for the ship have the advantages of being simple in structure, economical, reliable, accurate in positioning, low in positioning cost and low in energy consumption.

Description

Technical field [0001] The invention belongs to the technical field of ship and ocean engineering application, and specifically relates to a constant tension adaptive control system and method for marine multi-point mooring positioning. Background technique [0002] For marine engineering and special operations ships, maritime positioning is a very important working condition. Through the maritime positioning system, the operating ships can be moored and operated in the harsh marine environment. [0003] At present, marine positioning systems mainly include two types: mooring (anchor) positioning systems and dynamic positioning systems. Among them, the mooring (anchor) positioning system has the advantages of simple structure, economical reliability, convenient use and maintenance, etc., and mooring positioning methods are often used in not too deep waters (below 1500m), and are widely used in various engineering ships, In operations such as FPSO and semi-submersible platforms, th...

In other words, the single point mooring positioning system cannot achieve ship positioning accuracy under severe sea conditions

[0005] Although the existing multi-point mooring positioning system solves the problem of low ship positioning accuracy of the single-point mooring positioning system in harsh sea conditions, it generally has the disadvantages of complex structure and limited reliability. To develop a simple structure, economical and reliable The multi-point mooring positioning system is an urgent problem to be solved at present
