Xu, S., Rezanejad, K., Wang, S., Gadelho, J. F. M., and Guedes Soares, C. (2020), “Experimental study of the performance of a compact mooring system for a dual chamber floating oscillating water column device”, Proceedings of the ASME 2020 39th International Conference on Ocean, Offshore and Arctic Engineering (OMAE 2020), 28 June - 3 July, Fort Lauderdale, Florida, USA, paper: OMAE2020-18839.
In this paper, a compact mooring system concept is proposed. This novel mooring is composed of submerged buoy and three segments of nylon ropes, which is suitable for the large WECs and WEC array due to its high flexibility and small mooring radius. The performance of this mooring concept was studied by the experimental method when it was moored to an oscillating water column(OWC). Both the regular and irregular head sea wave tests were conducted. In order to study the influence of wave height on system dynamics, two series of regular wave tests with same periods but different wave heights were conducted. According to the experimental results, the six degrees of freedom motion responses of OWC and mooring tensions are analyzed. Besides, the energy conversion efficiency is evaluated based on the measured data.
