Hydrodynamic response of spar and semi-submersible interlinked by a rigid yoke - Part I: Regular waves

Experimental and numerical investigations on the hydrodynamic response of a spar and semi-submersible linked system under regular waves (Part I) and random waves (Part II) are presented. These studies were performed for two cases: the first case with the spar alone and the second case with a semi-submersible linked to the spar. The influence of the semi-submersible on the motion response of the spar and its mooring system are evaluated and presented together with acceptance criteria used in the industry. Experimental results are compared with numerical results and found to be acceptable. © 2012 Copyright Taylor and Francis Group, LLC.
