海洋钻井平台的井架在作业时受到各种环境载荷和自身工作载荷的作用，需要考虑多种组合工况和载荷成分。文中应用SACS有限元软件针对某升级钻井能力的平台井架建立三维有限元模型，对其在各种载荷和工况下进行直接计算分析，提出有效且经济的加强方案，使其能满足提高钻井能力后的要求。
海洋鑽井平檯的井架在作業時受到各種環境載荷和自身工作載荷的作用，需要攷慮多種組閤工況和載荷成分。文中應用SACS有限元軟件針對某升級鑽井能力的平檯井架建立三維有限元模型，對其在各種載荷和工況下進行直接計算分析，提齣有效且經濟的加彊方案，使其能滿足提高鑽井能力後的要求。

Various combined operation conditions and load components should be considered because the derrick of offshore drilling platforms are affected by the various environmental loads and self-loads under operation. This paper builds 3D finite element model of a platform with the upgraded drilling rig by SACS, performs direct calculation and analysis under the various operation loads, and puts forward the effective and economic reinforcement scheme which can satisfy the requirements after promotion.
