(Reporter Fu Yifei) The Norwegian offshore fishery project contracted by China Shipbuilding Heavy Industries Group Wugang Group was successfully delivered on November 3 at Beichuan Marine Engineering Co., Ltd., a Wuchuan Group located in Huangdao District, Qingdao. This is the world’s first semi-submersible deep-sea fishery, which combines Norway’s advanced breeding technology, modern environmental protection culture concept and the world’s top offshore engineering design. It is the world’s first R&D project in this field.
The fishery has a total height of 69 meters, a diameter of 110 meters and an empty ship weight of 7700 tons. It is resistant to typhoon 12. The service life is 25 years. The project is equipped with the world's most advanced salmon intelligent breeding system, automated security system and high-end deep-sea operating management system. The design staffing is 3 to 7 people, and the annual fish breeding capacity can reach 1.5 million.
According to reports, the project completed a series of major technological innovations during the R&D and construction process.
The new revolving door system carries the main functions of fishing grounds such as fishing net cleaning, automatic driving and catching of live fish, bottom dead fish collection, and flood prevention. With a diameter of 110 meters and a weight of several hundred tons, the portal frame can run on the track with millimeter accuracy. Its uniqueness, scientific and technological content, and technological precision are unprecedented in China's offshore industry.
The large dock loading process in fisheries is like "stacked wood." 26 giant segmented nodes, 13 super-long columns, 7 large-scale floating bodies, 12 "X" type intermediate reinforcement structures, 12 bottom radial type segments, 24 annular supports, 6 top cross-beams and A superstructure weighing several hundred tons is assembled into a “Sea Big Mac†under the premise of ensuring accuracy, fully embodying the scientific research and management level of the Wuchuan vessels as well as the collaborative cooperation capabilities of the participating parties.
At present, China has become one of the major ocean-going fishing countries in the world. Experts pointed out that the project is a "epoch-making" equipment for deep sea aquaculture, which will lead the technological revolution in the mariculture industry and promote industrial leaps, promote the transformation of fishery culture from offshore to deep-sea culture, and transform from cage-type culture to large-scale equipment culture. , From traditional artificial breeding to automated and intelligent farming. The delivery of the project has also become a good beginning for Chinese enterprises to fully enter the market of deep-sea breeding equipment.
