Abstract

The ocean spar sea station has not been widely applied in our country, but its good ability to resist deformation and characteristics of subsidence made it has an irreplaceable role in the deep water. If one deep sea cage can be developed with independent intellectual property rights on the basis of the sea station, it will have a significant impact on our country's aquaculture. In this paper, a single grid mooring sea station cage numerical model is built based on the lumped-parameter method and calculated under different sea conditions with OrcaFlex. Results show that under the combined wave-current action, the forces on mooring lines are strongly influenced by current velocity, followed by wave height and are hardly influenced by the period of waves. The maximum tension of the mooring lines occurs when the wave and current have a certain angle, rather than under parallel wave-current conditions. The maximum float rim pitch increases linearly as the flow velocity and wave height increase, and decreases as the period of the waves increase. In addition, the forces on cage and mooring lines may decrease obviously when the cage is submerged.
