摘　　要：采用FLUENT软件对一座具有双截面横撑的3 000 m深水半潜式钻井平台的横撑拖航阻力进行了研究,得到了拖航阻力随横撑间距的变化规律,结果表明,当横撑间距取小于5 m时,2根横撑的拖航阻力接近单根横撑的拖航阻力。本文研究成果可为今后的深水半潜式钻井平台船型设计提供参考。The towing resistance of two adjacent braces in a 3 000 m deep water semi-submersible drilling platform was studied here with FLUENT, and the change rule of the resistance with space was analyzed. According to the results, the towing resistance of 2 braces with a space less than 5m is closer to the resistance of only one brace for this particular platform. The research results may provide good proposal to the coming ship-type design of a new platform.
