Offshore aquaculture facility based on bulk carrier conversion

Abstract

The invention discloses an off-shore breeding facility based on the refitting of a bulk cargo ship. The bulk cargo ship is refitted into a floating offshore facility. There are several breeding cabins distributed under the deck, and a movable hoisting system is arranged on the deck. There is a water exchange system, and there is a cavity that provides buoyancy for the breeding facility sealed between the side wall of the offshore breeding facility and the outer wall of the breeding cabin. There are auxiliary breeding cabins and equipment rooms on the deck, and a water body monitoring system is installed in the auxiliary breeding cabin. A mooring device is provided at the front of the offshore breeding facility. The beneficial effect of the present invention is: it is suitable for being in the northern part of the Yellow Sea or other sea areas suitable for salmon farming, and the distance from the shore can reach 100-200 nautical miles. With the aid of a specially designed mooring device, it can resist the strongest typhoon that may occur in the area. Ensure that it can operate in fixed sea areas for 10 consecutive years under any sea conditions.

Description

technical field [0001] The invention relates to an off-shore fish farming system, which belongs to the technical field of fishery equipment. Background technique [0002] There are two types of fish farming facilities: inshore aquaculture and open sea aquaculture. Among them, inshore fish farming is widely used, but its disadvantages are obvious: one is serious pollution, and even frequent red tides, and the survival rate of fish farming is not high; the other is that it is seriously disturbed by bad weather , For example, typhoons and tropical storms that occur frequently in the coastal waters of China often destroy coastal fish farming cages on a large scale. Fish farming technology in open sea facilities is currently mainly used in the coastal waters of Norway, but because of its high construction and operating costs, it is only suitable for raising high-value fish species, such as salmon. The structure, molded depth (25 meters) and volume (up to 200,000 m) of bulk cargo...

Problems solved by technology

But its disadvantages are: the existing design is extremely expensive, and many special designs for the oil and gas industry are not suitable for the offshore farming industry

The offshore fish farming industry will need the assistance of a large number of auxiliary ships, such as: live fish transport ships, feed supply ships, refrigerated ships, etc. Since my country's offshore fish farming industry is still in its infancy, the construction of auxiliary fleets is even more lagging behind
