【摘要】 在线性三维势流理论的基础上,采用时域计算方法对BZ25-1油田16万吨级FPSO不同吃水条件下的碰底情况作了分析研究。数值计算结果与模型试验进行了比较,两者吻合较好,说明应用时域计算方法可以从理论上预报FPSO在浅水中的触底情况。这对我国渤海等浅水海域油田应用FPSO系统进行开发具有一定的意义。更多还原

【Abstract】 In this paper, time-domain numerical simulations are carried out on a 160 kDWT FPSO with a Yoke mooring system moored in BZ25-1 oil field with a water depth of 16.7 m. The results are compared with those of the corresponding model tests. Good agreement shows that the time-domain simulations can be used to predict the performance of the FPSO in shallow water reasonably. It is found that the touch of seabed by fully loaded FPSO occurs few times under survival storm conditions. Therefore, the FPSO should be less loaded than that in the fully loaded condition under the survival storms.更多还原
