在海洋平台拖航过程中,提前准确计算平台拖航阻力,选配动力合适的主拖轮,对拖航安全有着十分重要的意义.调研了各主流船级社拖航阻力的计算公式或推荐方法,以胜利石油工程公司典型自升式海洋平台为研究对象,进行了CFD/AQWA有限元数模计算,根据结果的对比分析,优选了适合国内海域平台拖航阻力的计算模型,并提出了适合的拖船选用安全系数.

In the course of towing of offshore platform, it is of great significance to calculate the towing resistance ahead of time and select the main tugboat with proper power for towing safety. In this paper, the calculation formulas or recommended methods for towing resistance of mainstream classification societies were investigated, and a CFD/AQWA finite element numerical simulation was conducted for the typical jack-up offshore platform in Shengli Petroleum Engineering Company.Based on the comparative analysis of the results, a suitable model for the calculation of towing resistance of platforms in domestic waters was optimized, and a suitable towing factor of safety was proposed.
