新型超大型浮式海上基地消浪室方案试验研究

新型超大型浮式海上基地（VLFOB）设计采用了由两层直立开孔式消浪墙组成的消浪室结构。根据内、外消浪墙开孔率的不同，提出6组消浪室方案。通过模型试验研究，对比分析不同消浪室方案下的消波效率和VLFOB水动力性能，结果表明：一般地，消浪室开孔率越小，消波效率越高，VLFOB的纵荡幅值和系泊力越大，单体间连接载荷相对较大；相同消浪室方案下，入射波能级提高使得消波效率降低；采用内外开孔率分别为0.16和0.24的消浪室方案，不仅消波效率较高，而且单体间的连接载荷也较小。

Experimental research on the wave-breaking chambers of Very Large Floating Offshore Base

Wave-breaking chamber, composed of inner and outer wave-breakers which are vertical and porous plates, is applied in the design of Very Large Floating Offshore Base (VLFOB). By using different inner and outer opening ratios, six wave-breaking chambers are proposed. Through experimental studies, the wave-breaking efficiency and the hydrodynamic performance of the VLFOB are compared and analyzed. The results show that the wave-breaking efficiency will be higher by utilizing the chamber with lower opening ratio. At the same time, the surge motion, the mooring force and the connector load of the VLFOB will be larger. For the same chamber, the wave-breaking efficiency decreases with the increase of the inci-dent wave energy. Among the six chambers, the best one is selected due to the relatively high wave-break-ing efficiency and low connector loads.
