초대형컨테이너선의 항만하역 시스템 개발 방향

Abstract

Above 120 vessels of 10,000TEU are currently on order including the 12,000TEU vessel. Many of these scheduled to enter service by 2011 on the Asia-Europe and Asia-America and trans-Pacific trades. Super-Containership has now moved firmly from concept to reality.

Automated container terminals have been being developed over the world for recent years and many countries are interested in it because the amount of containers exported or imported is rapidly increasing.

The conventional container terminals were not designed to control this kind of heavily many containers. They would face many structural problems soon or later, although they have managed to do well so far.

One of the most important things in developing automated container terminal is to develop the equipment able to handle many containers efficiently. Those are maybe automated transfer cranes, automatic guided vehicles, and automated quay-side cranes.

The word "automated" means the equipment is operated without drivers and those equipments are able to work, without any interruption in working schedule. Through the researches on the conventional transfer cranes, we decided that the structure of the conventional transfer cranes is not efficient in automated container terminal and it`s not possible to handle so many containers in limited time.

Therefore we have been studying on the proper structure of the automated container crane for past several years and a new type of transfer crane has been developed.

There has been a recent growth spurt in container line traffic. To reduce the sea transport cost per TEU, many ship owners have placed orders for even larger container ships.

The step towards bigger ships has been accelerating but the turning point towards the production of the larger ships was in 2000. Increased fuel and feeder service cost. among others, required by larger ships go beyond the immediate economies of scale and suggest that larger than the 12,000TEU will begin to negate any economy of scale generated by its size by regaining the use of a second engine.

An analysis of ship construction trends suggests that a 12,000TEU ship will be plying the seas by 2013. I suggest that the ultimate ship size is 12,000TEU, for the time being. As a container ship is enlarged, its draught, length and breadth are also logically bigger.

Container terminals must maintain their vigilance of these trends in order to anticipate the future of container liner needs. Deeper water depth and even larger container cranes with longer outreach are just a few of the changes that competitive terminals need to implement.

We also present analysis of the expected surroundings such as excessive competition between ship owners, loading/unloading system and planing for container terminal in the future.
