The maximum shipping capacity of the Suez Canal

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.     

船过苏伊士运河

我曾经是一位职业海员,先后有数十次往返过苏伊士运河的经历。直到前两年,当我离开远洋船队时,才仔细回忆起我们过苏伊士河的情景。当我从10月的北欧带着丝丝秋意赶往苏伊士运河入河口塞得港时,这里还是烈日炎炎,酷暑难当。那尊石雕镇河雄狮仿佛流着热汗在俯视着这条南北水上

A cost-benefit study of the Suez Canal large-scale dredging project

The choices faced by shippers are generally complex. Typically, the shipper is presented with a range of alternative carriers, each of which has its individual strengths and weaknesses. A survey of companies purchasing shipping services in an overnight RO/RO ferry trade was conducted to identify their priorities and to help understand and the decision-making process. The shippers were found to be conservative decision makers with a strong emphasis on quality of service.

Forecasting the Suez Canal traffic: a neural network analysis

Although the Suez Canal is the most important man-made waterway in the world, rivaled perhaps only by the Panama Canal, little research has been done into forecasting its traffic flows. This paper uses both univariate ARIMA (Autoregressive Integrated Moving Average) and Neural network models to forecast the maritime traffic flows in the Suez Canal which are expressed in tons. One of the important strengths of the ARIMA modelling approach is the ability to go beyond the basic univariate model by considering interventions, calendar variations, outliers, or other real aspects of typically observed time series. On the other hand, neural nets have received a great deal of attention over the past few years. They are being used in the areas of prediction and classification, areas where regression models and other related statistical techniques have traditionally been used. The models obtained in this paper provide useful insight into the behaviour of maritime traffic flows since the reopening of the Canal in 1975—following an 8-year closure during the Arab-Israeli wars (1967-1973)—till 1998. The paper also compares the performance of ARIMA models with that of neural networks on an example of a large monthly dataset.

苏伊士运河及其航行规则对舷梯和引水员软梯等的要求

苏伊士运河是在埃及境内,南北方向横跨苏伊士地峡,人工挖掘的无船闸海平面水道,其连接红海与地中海,该运河将非洲大陆与亚洲分隔开,且在欧洲与沿印度洋和西太平洋周边的陆地之间,提供了最短的海上航路。2015年8月6日,扩建后的苏伊士运河新航道开通。苏伊士运河由"苏伊士运河管理局"(SCA)负责管理、作业和维护,现行的SCA航行规则为2015年8月版,其与船舶设计、建造关系密切。文中对航行规则中的目次、舷梯和引水员软梯、系泊索、指示器、消防设备和起居舱室等作了介绍。
