等效水深截断系统模型试验结果可用性研究

Investigation on the Usability of the Model Test Based on Equivalent Water-Depth Truncation

以一工作水深为320 m的转塔式浮式生产储油系统(FPSO)为例研究了被动截断式的混合模型试验方法,选择截断水深为160 m,先后进行了截断系统和全水深系统模型试验,并对两者结果进行了比较.结果发现,在保证静力特性相似并且截断程度不大的情况下,等效水深截断系统模型试验能在一定程度上代替全水深系统模型试验.

A turret moored FPSO（Floating Production, Storage and Offloading units） in water depth of 320 m was selected to investigate the hybrid model testing technique based on the passive water depth truncation. The truncated water depth is chosen as 160 m. The model test of the truncated system as well as the full depth one is done successively. And the corresponding results are compared with each other. It was found that if the similarity of static characteristics of the two systems are ensured and the truncation degree is not too large, the model test of the equivalent water depth truncation system can substitute for the one of the full depth system to some degree.
