广州港曾经是中国唯一的对外开放口岸,并一直以来作为华南最大的综合性主枢纽港屹立在世人面前。今天,随着广州港南沙港区的建成投产,广州港跨越式的发展再次成为港航物流界关注的焦点。最新数据显示,2007年广州港完成货物吞吐量3.4亿吨,世界排名第5位,集装箱吞吐量超过920万TEU,广州港逐步成为华南集装箱运输枢纽港。为此,本刊记者专访广州港主体港广州港集团董事长陈洪先。 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
