The evaluation of safety of simulated maneuvers is frequently analysed by so called goal-line or point of interest in Korea. For the purpose of warning the risk in the proximity measure composed of only the goal-line analysis, this paper utilized Korea Institute of Maritime and Fisheries Technology(KIMFT) which houses a real-time, full-mission shiphandling simulator to examine the goal-line and in-length analyses in the outbound channel of Kwangyang port as an example. It used a 15,000 TEU container ship as a model under environmental conditions of the northwestly 26-knot wind and 2.2-knot ebb current. The result of two analyses showed the probability invading the channel boundary obtained by the goal-line analysis is a little greater than that of the in-length analysis. Therefore it was acknowledged that the proximity measure by the goal-line analysis alone may be followed by some risk. In addition, this paper was to suggest the closest distance to channel boundary from the ship's edge as one of proximity measures, instead of using the ship's deviation from the centerline of channel,

Recently, freight floe between south and north Korea is rising rapidly by increasing cf economical exchange between two Korea and growth of Gaeseoung Industrial Complex. Considering this trend of economic cooperation between two Korea, in addition to a land transportation route it is necessary to secure various logistics and transportation route. A barge transport system which has many merits such as a little initial investment and convenience of harbor loading/unloading has been also used to transport freight widely in the EU and USA. In this paper, firstly, a Gaeseoung industrial complex and its cargo transport are investigated and several candidate shipping routes which are using barge transportation system are proposed. And also we investigate a technical feasibility on a realistic possibility of shipping routes by some investigation activities. Finally, a suitable barge system of candidate shipping route(1) and(2) is proposed in this paper.

Dynamic analysis of a marine slender structure is often involved with contacts among bodies or between bodies and seafloor. This paper presents an efficient and general contact search algorithm for dynamics in the context of the compliance contact model. A global detecting method that a bounding box is divided into several pieces in global coordinate system is presented in this paper. The method has an advantage that the number of contacting searching am be smaller than other methods for a system. The developed an efficient contact search algorithm is applied to the simulation program of 3D nonlinear dynamics of slender structure. Some examples are presented to show the validity of the proposed method.

The wave load and its influence on the response of offshore structure have been well investigated through the statistical approach based on the linear theory. The linear approach has a limitation to apply the extreme condition such as extreme wave, which corresponds to extreme value of wave spectrum. The main topic of present study is to develop an efficient numerical method to predict wave load induced by extreme wave. As a numerical method, finite element method based on variational principle is adopted. The frequency-focusing method is applied to generate the extreme wave in the numerical wave tank. The wave load on the bottom mounted vertical cylinder is investigated. The hydroelastic response of the vertical cylinder is also investigated so as to compare the wave loads with the rigid body case in the extreme wave condition.

An OWC-type Wave Energy Conversion passes through 3 steps energy conversion process. This paper deal with the internal oscillating flow and effect of shape of air chamber and duct at setting place of turbine by numerical analysis using commercial CFD code, FLUENT. Air chamber and duct in OWC-type wave energy conversion are adopting sudden expanded and contracted form for high-efficiency. So, whole oscillating flow from OWC-type chamber to outlet duct through duct was solved by steady and unsteady analysis in order that flow efficiency of air chamber and duct was made better.

Recently satellite SAR techniques have become essential observation tools for various ocean phenomena such as wind, wave, and current. The CMOD4 and CMOD-IFR2 models are used to calculate the magnitude of wind at SAR resolution with no directional information. Combination of the wave-SAR spectrum analysis and the inter-look cross-spectra techniques provides amplitude and direction of the ocean wave over a square-km sized imagette, The Doppler shift measurement of SAR image yields surface speed of the ocean current along the radar looking direction, again at imagette resolution. In this paper we report the development of a SAR Ocean processor(SOP) incorporating all of these techniques. We have applied the SOP to several RADARSAT-1 images of the coast of Korean peninsula and compared the results with oceanographic data, which showed reliability of spaceborne SAR-based oceanographic research.

In general mechanical servo systems, friction deteriorates the performance of controllers by its nonlinear characteristics. Especially, friction phenomenon causes steady-state tracking errors and limit cycles in position and velocity control systems, even though gains of controllers are tuned well in linear system model. Even if sensor is used higher accuracy level, it is difficult to improve tracking performance of the position to the same level with a general control method such as PID type. Therefore, many friction models were proposed and compensation methods have been researched actively. In this paper, we consider that the variation of mover's mass is various by loading and unloading. The normal force variation occurs by it and other parameters. Therefore, the proposed control system is composed of main position controller and a friction compensator. A parameter estimator for a nonlinear friction model is designed by adaptive control law and adaptive backstepping control method.

The wedge type rail clamp compresses with small clamping force at first, and with large clamping force when the wind speed increases bemuse of the wedge working. At this time in order to display the wedge working, the rail clamp slips along a rail. If the supporter is not installed in the rail clamp when the wind speed increases more and more, the structure will occur overload which leads the structure to fracture. So the supporter has to be installed in the rail clamp. The proper position of this supporter is determined by the initial clamping force and the wege angle. Therefore in this study we adopted 5-kinds of wedge angle as the design parameters, and carried out the finite element analysis, in order to analyze the relationship between the initial clamping force and the position of supporter in the wedge type rail clamp.

It was decided by national vote in Panama to expand the Panama canal. Therefore 12,000TEU sized vessel can pass the canal from 2014. The Far East-North America shipping route, over than post panamax size vessels have to use other routes such as Mini land bridge instead of using the panama canal due to limitation of canal size. Therefore, some changes in the transport route in Far East-North America are expected duo to expansion of Panama canal. The objective of this paper is to analyze the transport cost between Far East and North America then compare the competition between panama canal route and land bridge route.

ILO has contributed for seafarers to promote conditions of employment and decent work through maritime labour standards. Between 1920 and 1996, a total of 39 Conventions and 29 Recommendations concerning seafarers have been adopted, which demonstrates the important part of ILO activities devoted to seafarers' questions. But many instruments were outdated, deficient and not reflective of modern practice, many contained technical detail which discouraged ratification. The Governing Body of ILO, at its 262nd Session(March-April 1995), decided to set up a Working Party regarding the revision of maritime labour standards. This Working Party initiated its examination of maritime instruments to 273rd Session(November 1998) of the Governing Body. The review made by the Working Party has concluded that existing maritime Conventions were considered either up to date or were identified for promotion, most of which were approved by the Governing Body. Therefore, ILO started to create a single, coherent instrument embodying as far as possible all up-to-date standards of existing maritime labour conventions. The Maritime Labour Convention 2006 was adopted in February 2006. This paper aims to analyze the significance of this Convention and the influence regarding to maritime labour affairs in the field of shipping industry.
