This study aims at newly constructing and evaluating performance of the stevedoring equipment systems in terminals. The stevedoring equipments used in conventional terminals are insufficient in flexibility in their functions or design structure, and most of the stevedoring systems based on such equipments have conventional design, therefore, limited in improving the productivity of terminals both in performance and functionality. The stevedoring equipment systems in terminals, in general, can be subdivided into 4 subsystems of quay, transportation, yard, and gate system, which carry out loading and unloading works with proper facilities and equipments. In this study, a design of next generation stevedoring equipment system comprised of various stevedoring equipments which have superior performance and functionalities to the conventional equipments was proposed, and its performance was evaluated.

This paper deals with High Stacking System(HSS) development to develop a next generation port handling system for accommodating mega-sized container ships. It aims to develop the HSS that maximizes handling capacity within the limited space of the port. The system is expected to resolve the problem of yard space shortage as well as utilize innovative technology to ensure high-performance and automation at the terminal so as to enhance stevedoring productivity. The main objectives of this paper is suggesting the design concept drawing the HSS terminal and simulation analysis was undertaken taking into consideration performance of handling equipment, and port handling system Design concept drawing of the HSS terminal and will be used as base data for basic design and detailed design in actual operations of the terminal in the future. The HSS, to be applied to both conventional and new terminals, is expected to act as a catalyst for enhancing the value-added at ports.

The purpose of this paper is to evaluate the quay crane productivity in automated container terminal with perpendicular yard layout. In particular, four quay crane (single trolley/dual trolley/double trolley/supertainer) are considered to evaluate the productivity on the terminal performance. Each quay crane load or unload containers by a different process. For each quay crane, two productivities are considered and compared: mechanical productivity, net productivity. As the net productivity of quay crane is significant, in this paper, an application of simulation model to simulate automated container terminal is developed and a wide variety of computational experiments were conducted.

According as the quantity of goods transported by ship is increasing about $7\%$ per year, a port environment is rapidly changing. To meet this situation successfully, the development of the next generation port loading and unloading system (LMTT) is studied. A Frame of shuttle car for LMTT(Linear Motor-based Transfer Technology) consist of three parts which are outer beam inner beam and cross boom. Outer boom supports a container and inner boom is a framework and cross boom reinforces outer and inner boom. In this study, we carried out the finite element analysis for the effect of cross boom on the strength and stiffness qf the frame according to the number if cross beam leading position of container, the distance ratio if inner boom from center.

The result is as follow ; When the load is applied on outer beam and inner beam concurrently and the number of cross beam is 5, that is the optimum condition in frame design.
