Groundbreaking for deep water wave laboratory

China's first large-scale deep-water wind-wave laboratory, covering 16,000 square meters, is expected to be completed by the end of 2026.

Construction of a large-scale deep-water wind-wave laboratory has begun in the coastal city of Dalian, northeast China's Liaoning Province, CGTN reported on November 9. The project is jointly funded by Dalian University of Technology and China Three Gorges Corporation. The new facility will simulate the turbulent marine environment under complex wind and wave conditions, and provide high-precision experimental simulation technology for the impact of turbulent marine environments on engineering structures.

According to Dalian University of Technology, this is the world's first large-scale deep-water wind-wave laboratory. The project has a land area of 16,000 square meters and a floor area of 8,100 square meters, and is expected to be completed by the end of 2026.

In marine environments, waves and wind affect offshore engineering facilities and are important factors that must be considered when designing and operating these facilities, according to Lyu Lin, deputy dean of the Department of Infrastructure Engineering at Dalian University of Technology.

The laboratory will provide high-quality research and development facilities and technical services to meet China's important needs such as offshore renewable energy development and large-scale cross-sea transportation infrastructure construction.

Developing deep-sea oil and gas resources is also one of the country's important needs. In May, China National Offshore Oil Corporation (CNOOC) announced the completion of the topside of a 15,000-ton offshore drilling rig. This is China's largest offshore drilling rig. At 95 meters long and 40 meters wide, the surface of the rig is equivalent to nine basketball courts.
