【摘要】：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。
[Abstract]:A new super large floating offshore base VLFOB is designed using a two-layer vertical perforated wave-proof wall. According to the different opening rate of internal and external wave absorbing walls, six groups of wave elimination chamber schemes are proposed. Through model test, the wave dissipation efficiency and hydrodynamic performance of VLFOB under different wave suppression chamber schemes are compared and analyzed. The results show that generally, the smaller the opening ratio of wave suppression chamber is, the higher the wave dissipation efficiency is and the larger the longitudinal swing amplitude and mooring force of VLFOB are. Under the same wave suppression chamber scheme, the wave dissipation efficiency is reduced by increasing the incident wave energy level, and the wave elimination efficiency is not only higher when the internal and external opening ratio is 0.16 and 0.24, respectively, but also in the same wave suppression chamber. And the connection load between the monomers is smaller.
