Experimental investigation on dynamic responses of spar platforms subjected to multi-directional waves

In the real sea, only multidirectional waves or short crested waves are found. Nowadays, designers tend to use the directional wave statistics for the design of offshore structures. The main reason is to obtain the optimum design of the structures for cost and time effectiveness. In this paper, a...
