Abstract

The semi-submersible wave energy aquaculture platform "Penghu" is located in the open sea area, with large waves and rapid currents. Therefore, it is required that the platform not only meets the needs of aquaculture, but also has the ability of efficient power generation as well as wind and wave resistance. It is of great significance for the engineering safety and design to study the hydrodynamics characteristics of the aquaculture platform and its mooring system under the combined action of waves and currents. Based on the three-dimensional potential flow theory, the first-order Taylor expansion boundary element method is used to calculate the hydrodynamics characteristics in the frequency domain, and the first-order wave force and second-order wave drift force of the platform under waves from different directions are studied. Indirect time-domain analysis method and asynchronous coupling method are used to solve the time-domain coupling dynamic solution of the platform and its mooring system. The time-domain motion of the platform and the tension of mooring lines under different wave-current conditions are analyzed. The results show that under conventional sea conditions in the South China Sea the platform has great hydrodynamic performance with obvious hydrodynamic interference between columns, and the second-order wave drift force are the least when the platform stays in following seas. Under the coupling action with the mooring system, the pitch and roll motion responses of the platform are most affected by the incident wave angle, the roll motion response of the platform is most affected by the significant wave height when it performs in following sea, while the pitch motion response is most affected by significant wave height when it performs in beam sea or under oblique waves.
