【摘要】：浮式平台是深海油气资源开发的重要装备。在浮式平台作业过程中,流力对平台的定位有直接影响,是平台设计时需要考虑的重要因素。当平台设计方案确定后,立柱的主尺度将不能改变,其流力将取决于截面倒角。采用FLUENT软件对不同截面倒角立柱的流力进行了计算。结果表明,立柱倒角对拖航阻力有明显影响,当立柱截面倒角大于2m时,流力可减少50%以上。研究结果可为浮式平台船型设计提供参考。
[Abstract]:Floating platform is an important equipment for the exploitation of deep-sea oil and gas resources. In the course of operation of floating platform, the flow force has a direct influence on the positioning of the platform and is an important factor to be considered in platform design. The main scale of column will not be changed, and its flow force will depend on the chamfer of section. The flow force of different section chamfering column is calculated by using FLUENT software. The results show that the chamfering angle of column has obvious influence on towing resistance. When the chamfering angle of column section is more than 2m, the flow force can be reduced by more than 50%. The results of the study can provide a reference for the design of floating platform ship form.
