等效水深截断的深海平台混合模型试验方法研究

Investigation on hybrid model testing technique for deep sea platforms based on equivalent water-depth truncation

以工作水深为320 m的转塔式FPSO为例,研究了等效水深截断的混合模型试验方法。选择截断水深为160 m,先后进行了截断水深系统和全水深系统模型试验,并进行了相应截断水深试验的数值重构和全水深系统的数值计算。结果证明混合模型试验技术是切实可行的,可用于深海平台的模型试验。

In this paper, a turret moored FPSO at water depth of 320 m is selected to investigate the hybrid model testing technique based on equivalent water truncation. The truncated water depth is chosen as 160 m. The model tests of the truncated system and the full depth system are carried out. And corre.spondingly the numerical reconstruction of the truncated system as well as the numerical calculation of the lull depth system is conducted. The results show that the hybrid model testing technique is feasible and can be used in the model testing of deep sea platforms.
