T.S. HANBADA has a relatively large hull and superstructures above the water line, so she has much of leeway or turning of bow with the effect of winds. Especially on berthing, unberthing and/or sailing on low speed, these effects take place more significant. Therefore, it was carried out the numerical calculation of the wind force and moments acting on the T.S. HANBADA, and then calculated the leeway angle and counter rudder angle with the relative wind direction and velocity. Also, it was suggested the maximum wind velocity which could be berthed or unberthed used by bow thruster and the tugboat operations in strong winds. These results will be great helpful to the vessels with large superstructures on ship's handling in harbour or tugboat operations.

It has already been two decades or more ever since the shipping and its related industries began to mature in advanced shipping countries. During that period, such countries have made various attempts for the survival of the industries. The advent of the so-called flags of convenience in a big way for the purpose of replacing crew members of their own expensive seamen by those of developing countries and the emergence of ship management companies, which are literally engaged in the management of ships, are the results of such movements. Some countries have been making efforts, as measures for the continued existence of the maritime industries, to create new marine-related businesses without regard to the traditional concepts of the industries. The movement toward the restructuring of a maritime society in Norway is well known as a typical example of such endeavors. The business of marine consultancy relating to maritime safety management field in our country is also a business that came into existence in such a stream toward the revitalization of the maritime society. In this paper, as well as placing in focus the current picture and problems of marine industries in our country, we would like to present approaches to tackle these problems employed by advanced industrial nations in the West, that is, moves toward the revival of maritime communities. Next, we propose, as one of the answers to solve such problems, the further development of a consulting business which takes advantage of simulators. Lastly, we show specific examples of application of a simulator to the consulting business, while commenting on the effects of its use.

This study analyzed the state of the vessels which were using the berth for dangerous goods more than its carrying capacity in the major dangerous cargo handling port of Ulsan in Korea, The result of the analysis showed that a ship which has 3 times more than the maximum berthing capacity was moored at berth. Accordingly, a simulation model for 50,000 DWT berth was built and carried out the mooring safety analysis with 50,000 DWT, 70,000 DWT and 100,000 DWT vessels by mooring assessment program. The evaluation was carried out according to the standard environment presented in OCIMF standards. 50,000 DWT vessel was evaluated to meet the acceptable criteria but, 70,000 DWT and 100,000 DWT vessels exceeded the acceptable limit as per external conditions. Consequently, safe mooring guidelines were suggested and also proposed the building of common 'Mooring safety guideline' for port with assessment of different cases.

Human error is an important cause of maritime accidents and the identification of human error is fundamental to maritime-accident preventions. In particular, the pattern of technical behavior taken in the circumstance of bridge teams(navigator & helmsman) provides important information to identify human error. The purpose of this study is to identify and analyze technical behavior pattern of bridge teams using Williamson's turn for rescue of persons overboard. The focus of this study is to build and analyze a cognitive model of the human behavior factors of the bridge teams in the process of implementing the experiments. The experimental environment was constructed using a ship-handling simulator and conducted an experiment on participants from 24 bridge teams. As a result of the experiment, it was able to identify the behavior pattern of the ship's maneuvering and maintain trajectory using the rudder and engine. This study is expected to correct human error in the bridge teams application to the certification and training of seafarers.

From the viewpoint of navigation safety, it would be best if it's possible to build a bridge whose main span is wide enough, however, sometimes it may not be possible due to geographical or economic reason To construct the bridge on the shipping route, consideration factors for marine traffic safety must be investigated and examined from the viewpoint of marine traffic engineering. This study aims to secure marine traffic safety and maintain smoothly traffic flow through assessment qf these factors. As the first step, examination factors such as traffic volume, ship size and bridge width were assessed quantitatively using marine traffic flow simulation technique.

Arbitration is the dispute methods for speedy and economic resolutions in international commercial areas. In maritime disputes cases in East Asia, Korea and Japan are the regional benefits to cover and deal with the maritime cases on arbitration. And Korea and Japan are the competitive maritime industry for heavy shipbuilding industry, cargo carrier, processing and transhipment service on ports, and ship financial services in national competitive areas. Japan is the Tokyo maritime arbitration commission(TOMAC) as an uniquely capable of dealing with arbitrations involving problems arising in the sea field. TOMAC provides amended its arbitration rules 2014 aiming at matching with the maritime disputes circumstances with three maritime arbitration rules as ordinary rules, simplified rules and the rules of small claims arbitration procedure. KCAB however, as the unique commercial arbitration board in Korea is dealing on all of the commercial disputes on only the international commercial arbitration rules in 2011. Though KCAB is dealt with maritime dispute cases on international arbitration rules in Korea, it is small and simple compared with TOMAC in Japan. Maritime disputes are highly complicated and embroiled with multi-parties contract and subcontracts arising under contracts relating to bills of lading, charter parties, sale and purchase of ships, shipbuilding, ship financing and so forth. This paper is to provides a discussion and comparison on recently arbitration rules focus on the maritime aspects on Korea and Japan. We need to consider to make an independent and special institute and maritime arbitration rules including the multiparty consolidation and med-arb provisions for handling the disputes and resolution of maritime conflict cases in Korea.

Automatic Collision Prevention Training and RADAR Simulation Training, designated educations by the STCW Convention, are essential for officers to complete in order to board a ship. Recently, designated education institution standard based curriculum and requirements of the necessary facilities have been placed as a regulatory advisory requiring each institutions to match this and introduce equipment for simulation education, the FMSS(Full Mission Simulator System). Since the introduction of this research until today, a survey has been executed in order to find out the effect of utilizing the FMSS in ARPA/RADRA/Simulation Training for a period of 1 year. The result showed that 2.13times have been more effective. In addition, based on the results, identifying problems that occur during the education period and providing solutions to these problems have been proposed.

Since Emma Maersk, which is a container vessel capable of holding a freight capacity of 11,000 TEU, was launched early last year, the appearance of the ULCS (Ultra Large Container Ship) will be expected in 5 years. That requires the high productivity, the high technology, the automation, and the high efficiency in port operations. GTO (Global Terminal Operator) and port equipment companies are striving for the prior occupation of the port market and the development of the port technology. Within the country, however, there has been few systematic, analytic, and detailed technology road map, and the effective execution of the development policy for the port technology and the activation of port industries has not been achieved. In this study, we deduces the development subject of the domestic port technology and analyzes the priority of them. In conclusion, we establishes the macro technology road map and the product-related road map for container ports in Korea.
