Constant tension elevated cable offshore adaptive control replenishment system and replenishment method

Abstract

The invention provides a constant tension highline maritime adaptive control and supply system and supply method. The system comprises a constant tension highline maritime supply subsystem and a constant tension highline maritime adaptive control subsystem; the constant tension highline maritime adaptive control subsystem is used for driving and controlling an outer index winch (3), an inner index winch (4), a highline winch (5) and a wave compensation device (6), so that a crane device (7) moves between a supply ship and a receiving ship. The system and the method have the advantages: (1) a highline adopts constant tension adaptive control, so that manual intervention s not needed in the supply process, vibration of goods on cableways is reduced and the supply efficiency is improved; and (2) wave compensation is performed on the highline by adopting a wave compensation technology, so that tension constant double closed-loop control of the highline is kept, relative movements of the two ships are compensated, safe and stable hoisting and landing of goods when the ships swing are ensured, and mutual collision between the goods and the decks of the working ship is prevented.

Description

technical field [0001] The invention belongs to the technical field of marine replenishment, and in particular relates to a constant-tension elevated cable sea adaptive control replenishment system and a replenishment method. Background technique [0002] With the gradual deepening of the ocean development strategy, ships are often unable to enter the port for replenishment due to various factors such as ports, waterways, and sea conditions. Therefore, ships and offshore platforms need to be replenished at sea to extend the endurance of ships. [0003] Replenishment at sea refers to: use the supply device on the supply ship to replenish the receiving ship with materials at sea, replenish the food, fuel oil, fresh water, spare parts, materials and other material reserves required by the receiving ship in time, and extend the stay time and activity range of the receiving ship at sea , to meet long-term large-scale marine activities.

AI Technical Summary

Problems solved by technology

[0006] During the offshore replenishment operation, it is necessary to keep the replenishment ship at a safe distance from the receiving ship. However, due to the influence of factors such as the marine environment and the replenishment device, the two ships will move relative to each other, resulting in the failure of the replenishment operation.

In addition, the automation level of the existing offshore replenishment technology is not high, the replenishment process requires manual participation to complete, and the replenishment efficiency is low
