半潜式钻井平台几类横撑形式的拖航阻力对比研究

摘要

Thus the software Fluent was used here to compute the drag resistance of the braces with different cross-sections (such as, round section, plate-shaped section), the results were got, and the fluid field around the braces was analyzed. According to the results, the drag resistance of the brace with a plate-shaped section will be reduced more than half. The results in this paper can be used as a reference for the sizing of a new drilling platform.%采用FLUENT软件对半潜式钻井平台结构的几种常见截面的横撑拖航阻力进行计算,得到了不同截面形式横撑的拖航阻力,并比较了其周围压力场差异.结果表明,板型截面横撑的拖航阻力要比小截面横撑少50％以上.研究结果将为今后的半潜式钻井平台船型设计提供参考.
