摘 要: | 以某典型转塔式FPSO为研究对象,利用大型海洋工程水动力及时域耦合分析软件AQWA对FPSO及其系泊系统进行相关计算比较分析;首先通过ANSYS建模并且划分网格,然后通过AQWA-LINE,应用势流理论进行水动力分析,并分别选择914.4m、1800m、3000m作业水深,进行相应的静力计算、运动响应对比分析以及锚链张力的对比计算,得出FPSO的静力、运动响应以及锚链张力随水深变化的规律。

Abstract: | Taking a typical turret FPSO as research object, this paper carries out the relevant calculation and comparative analysis of FPSO and its mooring system by AQWA software which is a large marine engineering software capable of coupled hydrodynamic and time-domain analysis. Firstly, it builds modeling and mesh by ANSYS, and carries out the hydrodynamic analysis with potential theory by AQWA-LINE. Then it performs static force calculation, comparative analysis of motion response and calculation of tensile force of anchor chain under the water depth of 914.4m, 1 800 m and 3 000 m. Finally it obtains the change law of static force, motion response and tensile force of anchor chain with variation of the water depth for FPSO platform. |
