CHANNEL WIDTH OF HARBOR ENTRANCE

The design of harbour entrances must be dictated by the size and manoeuverability of the largest vessel anticipated to enter the harbour and also the local factors, but it does not seem that the design of existing harbours considers very many of the above factors. This paper describes how a criterion of harbour channel width are expressed as a numerical formula by the above factors. The total width of channel is divided into three widths whose clearance are based upon the study of Panama Canal that is, (a) width of manoeuvring lane, (b) width of the bank clearnace lane, and (c) width of the ship clearance lane, and the total width manoeuvring lane, (b) width of the bank clearance lane, and a computer program called TRANSAP-LNG for system design and economic evaluation of LNG transportation systems. The system model includes all the stages related to LNG transportation, such as gas wells, gas pipelines, liquefaction stations, LNG tankers and gasification stations, and since these sub-systems, either single or multiple, are linked together as a total system, optimization of the total system of multiple projects can be made as well as optimization at lower system levels. Particularly, an optimized LNG tanker can be designed in view of optimization of total transportation project.
