Study on key techniques for submergence of HDPE submersible deep-sea cage

Abstract:

The interaction between HDPE submersible deep-sea cage and wave current was analyzed by a number of in situ tests for cage submergence. The submersible cage could not sink completely because the sinking speed of the pipe cabins was different. And another important reason was the cage barycenter drift due to the water flow in the pipe cabins.The key technology of net cage sinking is controlling the sinking obliquity and eliminating block of the exhaust pipeline.
