Wave-Current Interaction on Offshore Spar Platforms

Abstract—Various types of offshore structures have been designed since the beginning of oil and gas discovery. They are conventional fixed platform, compliant tower, tension leg platform, spar, and semi-submersible. The oil and gas exploration is now focusing in the deepwater regions as the nat...
