Team research achievements and application fields

    The team carried out innovative research on several “bottleneck” technical problems in the offshore aquaculture engineering equipment. The research results are widely used in nearly 50 enterprises and research institutes.  Remarkable economic and social benefits have been achieved.  The main research results are as follows:

1 Engineering design theory of offshore aquaculture facilities

    The theoretical system of hydrodynamic analysis of the large wind-wave resistant aquaculture facilities in the offshore sea is constructed, and the theoretical method of wind-wave resistant design with tow is solved. A new similarity theory for physical model test of flexible mesh structure is proposed. The problem of hydrodynamic physical model test method of cage is solved. The hydrodynamic numerical simulation method of "flexible + large displacement + large deformation" structure is established, and the accurate calculation of hydrodynamic numerical simulation of cage structure is realized. Developed the first domestic cage hydrodynamic analysis software, the calculation accuracy is 20% higher than the world's most famous Aqua-Fe software.
This achievement won the first prize of Science and Technology Progress of the Ministry of Education in 2015: Research and application of key technologies of new structures in offshore aquaculture.

                              Hydrodynamic analysis  Secure design approach

2 Design of land-sea relay aquaculture facilities and habitat construction technology

    The key technologies for structure design, product development and safety evaluation of land-sea relay facilities were broken through, and the autonomous research and development of land-sea relay facilities suitable for the complex sea situation in our country was realized. The design method of cage frame, net coat and mooring system is put forward. It provides core technical support for the design of offshore aquaculture equipment in our country the first set of HDPE gravity cage, the first 10,000-ton class floating fishing platform, the pile-type deep-sea aquaculture platform of the world's largest water body, etc. The key technology of land-sea relay breeding facility design and habitat construction suitable for the north was broken through. It ensures the efficient and safe operation of aquaculture production throughout the year.
This achievement won the first prize of Liaoning Provincial Science and Technology Progress in 2020: Research and development and application of key technologies for Land-sea relay breeding facility design and habitat construction.

3 Safety assessment and disaster mitigation of offshore aquaculture facilities

    It breaks through the technical problem of safety risk assessment and prevention of aquaculture facilities under extreme sea conditions and constructs a standardized system to promote large-scale industrial applications. An optimization analysis method for scale layout of facility aquaculture area was proposed. Developed China’s first safety assessment and early warning system for large offshore cages to provide real-time warning for the whole country. China’s first marine aquaculture facilities design national standard “Technical specification for design of ocean gravitate cage” prepared by the team presided over. Four series of standards for aquaculture facilities and equipment suitable for the characteristics of China’s sea areas were compiled, which significantly reduced the disaster risk of ocean aquaculture facilities. And the technical achievements have been widely applied in East China Sea, South China Sea, Yellow Sea and Bohai Sea.
The achievement was awarded the Second Prize of Science and Technology Progress in Liaoning Province in 2017, which was as followed: Research and Application of Key Technologies for Hydrodynamic and Safety Assessment of Offshore Anti-Wave Cage.

The research results are widely used in the east and south of the Yellow Sea and Bohai Sea in China, realizing the safe operation of the new offshore culture facilities in the open ocean with a water depth of 20-40 m. The device has resisted the climate of Grade 12 typhoon and storm surge for many times, and have successfully guaranteed the maritime safety of 2.083 billion yuan commercial fish since 2012. In addition，the water quality of aquaculture waters has been significantly improved (the nutrition index and pollution index have decreased by 97% and 87% respectively), the unit water quality has increased by 136%, and the social benefits are significant. According to the statistics of 9 representative mariculture engineering application units, the total newly increased profits in recent three years are 279.71 billion yuan, and the new increased value of output is 1.8395 billion yuan. The Ministry of Education believes that “This research results have promoted the industrialization process of marine aquaculture facilities and equipment in China, which has generally reached the international leading level”.
