"De-sail No.1" is the world's first 10,000-ton deep-sea aquaculture farm with float-truss hybrid structure. It's also the only one in the same ton class that has passed the structural safety test of super typhoon "Mangkhut" (Category 5 Hurricane) in the ocean working condition. During the 10-hour marine survival test period, the fishing farm showed good stability, no deformation, and all technical indicators of structural safety fully met the design requirements.
"De-sail No.1" can be set in the open sea area of 20-100 meters deep of offshore water.The semi-submersible technology allows for limited diving or surfacing,providing an integrated solution for catching, net changing and simple maintenance of the fishery. "De-sail No. 1" adopts the manufacturing technology of truss and floating structure to solve the problem of the hydrodynamic effect and manufacturing cost of the fishing farm with maximum, improve the water exchange inside and outside the fishing farm, and increase the efficiency of aquaculture.
It is equipped with breeding area, intelligent breeding control area, energy power area, production material storage and living area. It is equipped with modernized aquaculture process control equipment such as aquaculture feeding expert decision-making system, multi-channel automatic baiting system equipment,monitoring system equipment, wind-solar complementary energy system, seawater desalination equipment and net lifter, underwater net washer, etc., which can realize integrated management of aquaculture and unmanned aquaculture.
The total length is 91.3m, width 27.6m and depth 7.5m. The design draught is about 6.5 m, the effective volume of aquaculture water is about 10,000 m3, and the design service life is 25 years. It has the ability to withstand the wind of 17 grades, the height of the waves of 9 m, and the resistance to the currents of 1 m/s in the survival of the harsh sea conditions.
