Comparison of Wave-Induced Swing Motion of Offshore Structures under Irregular Wave Simulating Seabed Positioning by Crane

Youn-Ju Jeong and Min-Su Park

Abstract—In this study, in order to investigate wave-induced motion of offshore support structures simulating marine installation by crane lifting and seabed down positioning, wave-induced motion tests were carried out for the three types of offshore support structures under the irregular wave conditions. As the results of this study, it was found that the main factors influenced on the wave-induced swing motion of offshore support structures were the center of gravity and period of free decay motion. Wave-induced motions of GBS and Hybrid were lower than the Monopile since the centers of gravity were lower than the Monopile. GBS model indicated lower wave-induced motion than the Hybrid at the long period of wave condition, since the period of free decay motion of GBS was relatively longer than the Monopile and Hybrid.

Index Terms—Support structure, wave-induced motion, test, marine installation, irregular wave.
