Recently, considerable number of bridges crossing over navigable waterways are under construction for the connection of coastal islands with mainland and the optimization of logistic system However, the most planned bridges have been initiated without paying much attention to ships safety aspects but with great emphasis on the economic factors, it has often been confronted with difficult social issues arising from opposing views and conflicts between building bodies and affected port users. The main reason for the conflicts is the lack of standards or specifications on the bridge design The proper location and scale of sea bridges are suggested in this paper considering fairway design criteria of both domestic and foreign countries, status analysis on the designs of existing and planned bridges, investigation findings of bridge-related marine accidents, the views of pilots and navigators collected through questionnaire. Since there is no general domestic or international design rules on bridge's scale, the design standards proposed in this paper may be useful at initial design stage of bridge.

Recently, unmanned systems have been studied and developed in various areas including aircrafts, automobiles and vessels. In addition, many researches about unmanned systems in Korea have been studying actively with the advancement of IT However, it is not satisfied with the result of the researches and developments. Bemuse of the reason we've here tried to make a very small USV which is a barge type. We applied the Great circle navigation calculation based on GPS to the autonomous navigation algorithm and used the LabVIEW 8.2 developed by NI corp. for programming The engine and rudder were controlled by pulse width modulation method. The engine system was composed of the DC motor and ESC(Electronic Speed Controller). It was also applied by the direct cooling system using DC motor pump. A very small USV was designed and made by ourself and it was verified the effectiveness of autonomous navigation algorithm through the tests at the sea

The influence of different appendage shape on the characteristics of hydrodynamic forces on Manta-type Unmanned Undersea Test Vehicle(MUUTV) was discussed experimentally. Fuselage only MUUTV model and two types of MUUTV model with different appendage geometries were considered as the subject of discussion Oblique tow experiment was carried out in circulating water channel with three MUUTV models. A point of difference in hydrodynamic force characteristics among three models was indicated. Furthermore, the linear hydrodynamic derivatives obtained from model experiment were compared with theoretical calculation results from slender body theory, added mass theory and etc. Based on the hydrodynamic force characteristics, motion stability of two types of MUUTV model with different appendage geometries was compared each other. Through the above analysis, the more suitable shape of appendage geometry was made clear.

The Very Large Marine Structure has been widely used new method of ocean space instead of method for reclamation Therefore, VLFS is proposed to coincide on such request. It can be established regardless of nature of soil and height of water, and stream of flow exists under the floating structure, there is seldom effect in natural environment. Fuertherrnore, it can do easily to do assembly and taking to pieces due to expansion or removal. Based on the regulation by class, VLFS have to possess more than enough structural strength against severe wave loading induced by green sea condition Therefore, There are performed structural simulation as well as experimental test about expected loading scenario in order to examine the safety of structure. Up to now, various examinations based on the strength limit value of the main structural material have been done based on the elasticity response analysis. However, there is little finding about the collapse behavior and the safety when the load that exceeds the collapse of the material acts. In the present study, we investigated the collapse behavior based on the ultimate limit state calculated by FE-analysis.

We have been developing an underwater robot for harbour construction using a parallel mechanism The robot is attached to the rope of a crane, which curries a large stone into the undersea The robot's yaw and pitch are controlled by hydraulic cylinders but its roll is uncontrollable. We mount propellers in both side of the robot to generate the roll motion This paper studies on the control for the roll motion of a underwater robot. A gyro-sensor is used to measure the angle in a roll motion We develop the dynamic model to describe the robot's roll motion by a second order non-linear system and identify the model parameters by recursive least square and adaptive identifier. PD control, recursive model based control and adaptive model based control are applied with the dynamic model which computes the control input to compensate disturbances. This paper introduces the underwater robot system and presents the simulated and experimental results of the proposed controller.

Container crane is main equipment in container terminals and it determines the productivity and the efficiency of container terminals. The typical type of container cranes has the single trolley and one among advanced types of them has the dual trolley. The objective of this paper is to analyze the buffer size of a container crane with the dual trolley in container terminals. We present a simulation model for analysing the buffer space of a container crane with the dual trolley. The buffer space is located between main trolley in sea-side and second trolley in yard-side. We performs various simulation experiments and analyze the buffer size to estimate the required productivity.

The issues of environmental pollution and labor safety on ship recycling in the undeveloped countries such as India, Bangladesh, etc have been proclaimed. For this, IMO has been actively participated in resolving such problems since 1998 and then finally the International Convention for the Safe and Environmentally Sound Recycling of Ships is going to be adopted in this year. The convention provides the design, construction, operation and preparation of ships in order to facilitate safe and environmentally sound recycling as well as the safe and environmentally sound operation of ship recycling facilities. Therefore, the purposes of this study are to introduce the major contents of ship recycling convention and its time of entry into force and to analyse stakeholders' strategies toward it so that Korea will have a better position for the establishment of a mechanism regarding regulation stringency on environmentally sound ship recycling.

Most domestic container terminals are lack of container storage capacity compared to the throughput of container. The main reason is the difference between the theoretical capacity applied to the development of terminals and the real capacity of a berth Another reason seems to be the increase of the container crane in number per berth to match the need for the getting larger vessel, which is resulted from the increase of the berth capacity from the start. This study, therefore, aims to suggest the economic size of container yard by comparing the existing one. For this the berth capacity was recalculated, the required yard size derived considering up to 10,000TEU vessel and then cost comparison done.

If we think about the form of housing architecture, we can find a general or typical type has been through the architectural history. because the formal transformation in housing architecture is very difficult. Recently, there are many housing works in powerful ocean state, netherlands that was different from the typical type in the form of housing architecture. This study focusing on the formal characteristics in such works. Such distinctive works in netherlands is the result from an attempt to fulfill the diverse needs of our contemporary society and in an effort to refuse the typical type of the modern architecture. The main purpose of this study is to reveal the meaning of typological transformation in the contemporary' housing architecture.

Recently, the number of design for open-spaces at waterfront, such as open-air restaurant and cafeteria, has been increasing to provide openness and natural environment of waterfront. However, when planning open-air restaurant and cafeteria, it is essential to investigate the climate characteristic of waterfront, especially wind environment, since the waterfront has a special quality of climate like low-temperature and strong wind which differs from downtown or inland In this study, wind environments of Haeundae, Suyoungrnan, and Gwanganli, the famous waterfronts in Busan, were investigated for design of open-air restaurants and open cafeterias. The main results were as follows. 1) the waterfront area of Haeundae, Suyoungman, and Gwanganli is suitable for open-air restaurant and open cafeterias; and 2) the appropriate period for open space in this area is from the end of March to November.
