<正> 已经出台的《港口法》规定我国港口经营将实行准入制度。从事港口经营,需要向负责港口行政工作的部门申请取得港口经营许可。山东从实际出发,已经首先在内河实行了港口经营许可证制度。笔者结合开展港口经营许可证制度以来的工作实际,对港口经营实行准入制度做如下探讨。 一、港口经蕾实行许可制度的必要性 改革开放以来,我省港口(包括货主码头和装卸站点,下同)发展迅速,为经济发展起到了良好的促进作用。但同时也存在港口的低水平重复建设,经营行为不规范的问题。内河港口特别是京杭运河(山东段)港口在建设规模和数量等方面都有较快发展。至2001年底,京杭运河(山东段)及其支流共有港口(装卸站点)160处,但由于历史原因,内河港口在建设和经营方面存在的矛 相似文献

为提升江苏内河集装箱运输船舶标准化水平,实现船型与船闸、航道等通航基础设施发展相匹配,通过梳理内河标准船型主尺度标准和通航管理规定的修订情况,结合京杭运河江苏段集装箱营运船舶的调研,在船舶主尺度、舱室布置、船体结构和新能源动力的应用等方面分析江苏内河集装箱船标准船型的设计要点,完成48 TEU、64 TEU和96 TEU标准集装箱船设计。虽然受限于内河航运关注船舶成本的现状,标准集装箱船的设计更多采用传统基础船型设计思路,但研发运用先进技术、满足内河EEDI的绿色节能型船舶是标准船型的重要发展方向。 相似文献

This paper considers the determination of the maximum shipping capacity of the Suez canal. Initially, some assumptions are made in order to calculate the ‘theoretical’ maximum capacity in terms of ‘standard ships’. This last term defines ships which transit the Canal at a given speed and at a given time interval from the vessel ahead and astern. Data has been collected from the Canal Zone, the analysis of which provides the necessary information regarding speeds of vessels at different sections of the Canal, time gaps between different classes of ship at different nodes of the Canal, and relationships between time widths of convoys and numbers of ships in those convoys at different points of the Canal. This data has then been used to calculate the maximum capacity of the Canal in terms of ‘real ships’. For that purpose four schemes have been devised, each taking a different mix of categories of ships. A sensitivity analysis has been undertaken in order to investigate the effect of each class of ship on the real maximum shipping capacity of the Canal. The last two schemes take into consideration the effect of the future introduction of supertankers. 相似文献

ABSTRACTThe Mega-ships, the maximum containerships represented by 20,000TEU-class (LOA:400m, Breadth: 60m, Draft: 16m) which are able to transit both the Malacca Strait and the Suez Canal, have emerged in 2013, aiming at lower shipping cost by economy of scale. At the same time, they inevitably increased port calls in a rotation to collect more cargo demand, resulting in the longer transit time than ever before. Taking this trend into account, the authors proposed the quick delivery scenario between East Asia and Northwest Europe by the NSR (Northern Sea Route)/SCR (Suez Canal Route)-combined shipping, of which 4,000 TEU ice-class containership transits the NSR during the summer season and the SCR in the wintertime, based on a year-round scheduled operation. The quick delivery scenario gives the shorter transit time at an affordable shipping cost depending on the NSR navigable season length. However, the quick delivery scenario cannot avoid uncertainties in navigation especially via the NSR in the summer season, due to rough weather, sea ice, low visibility and icing in the icy water section of the NSR. The authors preliminarily concluded that a year-round scheduled operation of the NSR/SCR-combined shipping will be secured, if the practical navigation schedule is appropriately prepared. 相似文献
