【摘要】：随着海洋工程的飞速发展,针对溢油回收的浮式储油罐的应用和分析越来越受到重视.浮式储油罐在不同水深下的锚链布置形式对其运动和动力响应的影响是设计者们尤为关心的问题.文中首先对一浅水(水深=28 m)工况下的3种锚链布置形式的浮式储油罐动力响应进行了数值模拟,然后对更大水深(水深=60,100 m)的不同锚链布置形式分别进行了响应的数值模拟,对计算结果做了分析,并对未来的浮式储油罐系泊形式设计提出了建议.文中采用自主开发的、基于RANS方程的粘性流体求解器naoe-FOAM-SJTU并利用集中质量法求解锚链力.
[Abstract]:With the rapid development of marine engineering, more and more attention has been paid to the application and analysis of floating oil storage tanks for oil spill recovery. The effect of anchor chain arrangement on the motion and dynamic response of floating oil storage tank under different water depths is of particular concern to designers. In this paper, the dynamic responses of three types of anchor chain arrangement in a shallow water (water depth of 28 m) are numerically simulated, and then the response of different types of anchor chains with larger water depth (water depth of 60100 m) is simulated respectively. The calculation results are analyzed, and some suggestions for mooring design of floating oil storage tank in the future are put forward. In this paper, a self-developed viscous fluid solver naoe-FOAM-SJTU based on RANS equation and lumped mass method are used to solve the chain anchoring force.
