海洋平台环境参数的单因素设计标准无法反映真实海况,文章针对该缺点提出了基于最大熵边缘的三维嵌套逻辑模型。该模型采用的最大熵边缘可以涵盖大多数设计线型,如Gumbel分布、Weibull分布、对数正态分布等;三维嵌套逻辑模型可以反映海洋环境参数的相关关系及变量的不对称性。总结并提出了三种海洋环境条件设计标准,即单因素统计方法、条件概率分布设计法和联合环境条件设计法。利用南海涠洲岛后报的年极值风速及对应有效波高、平均周期数据,对三维模型和海洋平台环境条件联合设计标准进行了实例验证。结果表明,三维模型对数据拟合良好,联合设计标准更符合实际。 相似文献

The South China Sea has attained global attention because of terraria disputes over oil, gas, fisheries and other resources in the sea area. Compared with the valuable natural resources, the underwater cultural heritage is not recognized or considered, but is an important legacy of many losses of vessels over centuries. Recently, the surrounding states in the South China Sea have taken measures to preserve underwater cultural heritage in their sea waters. However, the current complicated situation of the South China Sea intensifies the difficulties of protection of underwater cultural heritagein that area. There is an important and interesting potential issue of identification of ownership of underwater cultural heritage because of differences of legislation and claims to jurisdiction. Under the current information of legislation of some states in the South China Sea, it can be understood this issue cannot be avoid on the protection of underwater cultural heritage. This article discusses potential disputes over ownership of underwater cultural heritage in the South China Sea based on the different legislation of several states (China, Vietnam and Philippines) and proposes some possible suggestions for resolving the issue of ownership, rather than performing a primary research. 相似文献

The South China Sea contains tremendous oil and gas resources in deepwater areas. However, one of the keys for deepwater exploration, the investigation of deepwater floating platforms, is very inadequate. In this paper, the authors studied and compared the hydrodynamics and global motion behaviors of typical deepwater platforms in the South China Sea environment. The hydrodynamic models of three main types of floating platforms, e.g. the Semi-submersible, tension leg platform (TLP), and Truss Spar, which could potentially be utilized in the South China Sea, were established by using the 3-D potential theory. Additionally, some important considerations which significantly influence the hydrodynamics were given. The RAOs in frequency domains as well as global motions in time domains under time-varying wind, random waves, and current in 100-y, 10-y, and 1-y return period environment conditions were predicted, compared, and analyzed. The results indicate that the heave and especially the pitch motion of the TLP are favorable. The heave response of the Truss Spar is perfect and comparable with that of the TLP when the peak period of random waves is low. However, the pitch motion of Truss Spar is extraordinarily larger than that of Semi-submersible and TLP. 相似文献

Sovereignty claims over insular features and maritime jurisdiction in the South China Sea have been disputed for decades, and a governance regime to address ocean-related issues is urgently needed. This article first introduces the notion of a regime, and examines details of cooperation mechanisms in the Polar Regions. Lessons that can be applied to the South China Sea include that both soft and hard law regimes work to bring States concerned together to cooperate on the “commons” issues even when military conflicts or sovereignty disputes still exist. Consensus among bordering States would be necessary to make the South China Sea a “zone of peace.” Mechanisms that accommodate the various sovereignty claims and freeze existing and new claims to, as well as to prohibit military activities in, the South China Sea are recommended. Lastly, if a cooperative mechanism were to be established in the future, the Arctic regime would be more applicable to the South China Sea than the Antarctic regime due to their geographic nature. Thus, only States bordering the South China Sea should have voting and decision-making rights in the cooperative mechanism. As always, the political will of all parties is paramount to the success of such an endeavor. 相似文献
