In recent trends of the enlargement and specialization, container ship, LNCG, PCC and passenger ship which have relatively large hull and superstructure above the water line, are already being operated in the world It is very important information for the safety operation of these vessels to estimate the ship's performance under the specific wind condition while berthing, unberthing or low-speed sailing. In this paper, the effect of wind force and moment acting on the training ship HANNARA is investigated by using the numerical calculations. The results of drift angle and counter rudder angle with the relative wind direction and force, the critical wind velocity with the ratio of wind velocity and ship's speed and maximum heeling angle with the wind velocity are shown The presented results can be applied directly to T/S HANNARA in berthing maneuver and avoiding typhoons, and utilized as an educational materials.

It is very important in the navy operation to forecast and allocate appropriate petroleum requirements of a certain class of ships for the next year. The amount of petroleum requirements is very much dependent on the number of operating and training days or the running time of the main engine and the gas turbine of the ship. Two regression models were estimated and analyzed from real data obtained from several ships operated during the past three years. Finally, the amount of petroleum requirements that a ship is expected to spend for the next year can be estimated by using this estimated regression model based on operating hours of main engines and gas turbines of the ship.

Since it is very important for an ocean-going vessel to transmit information quickly and accurately to her owner or charterer not only for the ship's safety but for economic operation of the ship, some newly-built automated vessels equipped with automatic information transmission system which consists of INMARSAT-C and specially-designed computer. This system, however, is not applicable to the existing vessel without chaging her equipments and, furthermore, is too expensive for small shipping companies to fit out such a system on their vessels. Therefore, we propose a low-priced information transmission system which consists of a personal computer and communication equipments in the existing vessel, and in this paper, as the groundwork of the proposed system, we have made up the ship's position transmission system which is composed of and IBM AT-compatible, PC, INMARSAT-A and a GPS receiver. As the test result of the system through sea trial on the training ship 'HANBADA', we confirmed that transmission of the ship's position was achieved succesfully and consequently there could be high possibility of cost-effectiveness of the proposed system.

This study represents a fundamental research for a passenger-ship escape guidance system that is a ship-borne agent, and it is for the support of escape decision-making by providing accurate maritime safety information in real time. We conducted a passenger escaping experiment on a training ship, SAEYUDAL, using the situation-aware escape guidance system, which has been developed for on-board application based on products for buildings. It is shown that the system contributes to the shortening of the escape duration and the dispersion of the escaping persons by generating and guiding the safe escape routes which dangerous areas are considered. From the experiment on ship's heeling condition, it is revealed that the heeling angle is linearly related to the escape duration. Therefore, this study shows that the shortening of the escape duration enables a safe and rapid mustering that is the most important process under emergency and appropriate incident responses to minimize loss of lives.

In the current situation where clearly the ship officer is avoiding boarding, the purpose of this study is to investigate the satisfaction of onboard training in shipping companies during the COVID-19 situation and to suggest plans to improve onboard training. Furthermore, by improving satisfaction, students of maritime university can improve their career awareness as a ship officer in the future. The survey was conducted with the cadets of Mokpo Maritime University after completion of onboard training in shipping companies. The questionnaire contains seven factors: education administration, education contents, officer, facility, education ef ect, education satisfaction and career awareness. The survey analysis results indicated that the satisfaction with education administration and education effect was relatively low, and the satisfaction differed by gender and vessel type. In addition, hypothesis verification revealed that the education contents did not have a positive effect on education satisfaction and career awareness. Furthermore, a great correlation existed between education satisfaction and career awareness. We suggested that education and promotion must be improved before onboard training. In addition, the officer must be educated on the method to teach cadets and establish a training plan such that the officer can systematically guide the cadets with an educator mindset.

Estimating ship motion is difficult because it take place in complex environments.. Estimating ship motion is an important factor in ensuring the safety of ship, so accurate estimates are needed. Existing motion-related studies compare the apparent motion of the model acquired and the reference model by experimenting with the ship motion on a particular alignment, making it difficult to intuitively estimate the hull motion. This study introduces the concept of estimating the characteristics of ship motion as a transfer function through pole-zero interpretation and frequency response analysis by applying the method of transfer function of Linear-Time Invariant system. Ship motion analysis model using Linear-Time Invariant system is consist with 1) wave as input signal 2) ship motion as output signal 3) hull defined as black box. This model can be defined by numericalizing the ship motion as a transfer function and is expected to facilitate the characterization of the ship motion through pole-zero analysis and frequency response analysis.

The International Maritime Organization (IMO) has been regulating emissions by making mandatory the compliance with institutions aimed at protecting air quality such as the Energy Efficiency Design Index (EEDI), Ship Energy Efficiency Management Plan (SEEMP) and Tier III. Under the circumstances, one of the response measures considered to be the most feasible is the replacement of existing marine fuel with Liquefied Natural Gas (LNG). The industry has been preemptively building infrastructure and developing and spreading engine technology to enable the use of LNG-fueled ships. The IMO, in turn, recently adopted the International Code of Safety for Ships Using Gases or Other Low-Flash-Point Fuels (IGF Code) as an institutional measure. Thus, it is required to comply with regulations on safety-related design and systems focused on response against potential risk for LNG-fueled ships, in which low-flash-point fuel is handled in the engine room. Especially, the Standards of Training, Certification and Watchkeeping (STCW) Convention was amended accordingly. It has adopted the qualification and training requirements for seafarers who are to provide service aboard ships subject to the IGF Code exemplified by LNG-fueled ships. The expansion in the use of LNG-fueled ships and relevant facilities in fact is expected to increase demand for talents. Thus, the time is ripe to develop methods to set up appropriate STCW training courses for seafarers who board ships subject to the IGF Code. In this study, the STCW Convention and existing STCW training courses applied to seafarers offering service aboard ships subject to the IGF Code are reviewed. The results were reflected to propose ways to design new STCW training courses needed for ships subject to the IGF Code and to identify and improve insufficiencies of the STCW Convention in relation to the IGF Code.

The purpose of this paper is to develope a training model and to make a syllabus for electro-technical officers(ETOs) on ship. In order to complete the purpose, firstly we study on qualification for electro-technical officers and also examine the foreign, domestic cases. Secondly, through the STCW convention and the IMO Model Course 7.08, we have compared the standards of competence for officers in charge of an engineering watch and ETO, and analyze the additional standards of competence to acquire the ETO's licenses. Finally, based on the results of this, we will suggest the development of a training model that officers in charge of an engineering watch must complete in order to obtain an ETO's license. This paper is expected to be useful in the educational institution preparing for training course.
