摘要：
Blisters are commonly attached to the columns in the longitudinal direction to improve the per formance of semi-submersibles. In order to investigate the influence of the blister and its section shape on the hydrodynamic performance of a semi-submersible, numerical simulations and model tests were conduct ed to comparatively analyse the results of the natural periods, damping coefficients, motion RAOs, mean drift forces, and motion response in irregular waves. The results show that the longitudinal blisters of col umn can reduce the longitudinal mean drift force of the platform and the RAO in pitch direction. The mo tion response under extreme sea conditions is improved. The section shape of blisters has no influence on the hydrodynamic performance of the semi-submersible. © 2018, Editorial Board of Journal of Ship Mechanics. All right reserved.
