Self-propelled self-elevating mariculture ship and operation method thereof

Abstract

The invention discloses a self-propelled self-elevating mariculture ship and an operation method thereof, and relates to the field of ocean engineering equipment design. The self-propelled self-elevating mariculture ship is characterized in that net cages are connected with a hull through net racks, and lifting and fixing of the net cages are achieved by using a net cage lifting and locking system. In the culture state, the culture ship hull is supported at a certain height above the water surface through multiple pile legs, the hull is prevented from being directly acted by wave current loads, and shaking of the hull is reduced; after culture is finished or when typhoon needs to be avoided, the hull is lowered to a floating state through a lifting system, the pile legs are folded, and moving navigation is achieved through a propelling and steering system; compared with a floating type culture ship, corrosion caused by the fact that the hull floats in seawater can be relieved, fatiguedamage of the hull structure under the long-term action of wave flow is avoided, and hull shaking is small; the self-propelled self-elevating mariculture ship has the self-propelled characteristic, and the maneuverability of net cage culture is greatly improved; and the net cages can be prevented from bearing huge wave force on the water surface, shaking of net cage systems is reduced, and the structural safety of the net cage systems is improved.

Description

technical field [0001] The invention relates to the field of marine engineering equipment design, in particular to a self-propelled self-elevating seawater farming vessel and an operation method thereof, which can realize classified cultivation of different fishes and autonomous migration of breeding net cages. Background technique [0002] With the development of the economy and the improvement of people's living standards, the demand for aquatic products is also increasing, and the production capacity of my country's marine fishing industry has reached the upper limit, and the development of high-level aquaculture as soon as possible has become an important way to solve this problem. Compared with the nearshore aquaculture industry, deep-water aquaculture has less environmental pollution, high fish survival rate, fast growth, and good quality, but the deep-water operation environment is poor, the cost is high, and the technology is more complicated. [0003] At present, de...
