Semisubmersible drilling platforms have several features such as great anti-wave ability, excellent seakeeping performance, vast deck area and loading capacity and higher working efficiency; therefore, they have unmatchable advantages over other platform types in exploring deepwater energy resources. Taking the deepwater semisubmersible drilling platform ＂Ocean Oil 981＂ as an example, which is built in Shanghai Waigaoqiao Shipbuilding Co., Ltd, this paper summarizes several main applications such as finite element calculation, ultrahigh strength steel welding, platform antityphoon pier mooring, vibration and noise reduction and weight control during the construction process, so as to accumulate some experience for future developments.
