Ulsan Port is in the situation which the harbour limit and anchorages are less narrow than other trading ports and the occurrence probability of marine accidents is high due to heavy marine traffic Especially, the shortage of anchorages will become worse in case that the number of inbound and outbound vessels increases according to the development of Ulsan New Port. We will find and suggest the plan to enlarge the harbour limit essentially needed to expand anchorages in this research The reasonable type of harbour limit which is based on the survey by a group of experts, was determined after the decision of the range of harbour limit to accommodate the relevant anchorages.

International Maritime Organization (IMO) has established standards for ship manoeuvrability and applied these standards for vessels over 100 meters in length that built since 2004 (IMO, resolution MSC.137[76]). These standards are no exception to fishing vessels. In this study we carried out a manoeuvring simulation of the new model ship (Stern trawler) of fisheries training ship of Pukyong National University based on Kijima's empirical formula. The formula takes into account of the effect of stern shape or does not take into account of the effect of stern shape. Also we checked whether the simulation results of turning motion of model ship meet IMO manoeuvrability criteria and then compared trajectories between the simulation results of model ship and the results of real sea trial test of the existing ship. In conclusion, Kijima's empirical formulas can estimate the manoeuvrability of fishing vessels at design stage approximately, it needs more parameters of fishing vessel own in case of expressing the manoeuvrability of fishing vessel accurately.

The model for ship maneuvering simulation is to enhance the competence of officer's ship maneuvering skills such as navigation equipment operation, collision avoidances, countermeasure an emergency situation so on. Despite using such ship maneuvering model, critical maritime accidents are occurred periodically in the world. To find adequate simulation model to evaluate competence abilities of deck officer who have maneuvering skills with some competence levels, we search the standard ship maneuvering method representing on the part 3 Person Overboard(POB) to onboard emergences of IAMSAR manual. Moreover we monitor the officer's human factors appearing during education and training and consider the use of human factors as fundamental data.

The International Convention on Standards for Training, Certification, and Watchkeeping of Seafarers (STCW) outlines the qualifications that maritime cadets must meet in order to serve as merchant marine officers. Maritime English is one of the most essential qualifications for STCW, and each national authority is implementing Maritime English education that complies with national and international regulations. In this study, an English proficiency background survey was conducted to investigate the factors related to the Maritime English skills and competencies. In line with this, maritime cadets utilized the Standard Maritime English Communication Phrases (SMCP) learning platform to track their learning progress and its efficacy. This study examined the applicability of the automatic scoring platform for Maritime English education, as well as its future potential for widespread use in the maritime education field.

Modern manufacturing needs a great number of advanced engineers. China has the world's second largest equipment manufacturing and electronic information industry, and in 2020, the shortage of talented personnel in key industries will be more than 5 million in China. Universities and colleges are the main places to cultivate engineering talents. In this paper, we will introduce a multi-level engineering talents cultivating system we have applied in Dali University, China for more than 4 years. Under this training system, we have achieved some gratifying results.

Various kinds of ship are operated to transport cargo or passengers at sea in the world. Most of the important auxiliary machineries installed in those ships are fluid machineries such as pumps, compressors, and fans. A large percentage of fluid machinery is pumps which are classified turbo and positive displacement pumps. This paper analyzes only positive displacement pumps. This thesis has two aims: (a) to analyze the present status of pumps installed in merchant and training ships and (b) to find the correlation among sea going pump kW, port pump kW, total pump kW, GE kW, ME MCR, number of pumps, ME kgf, pump kgf. Based on ship's type, this paper seeks to find special characteristics as a result of analyzing head, flow rate, and kW. Moreover this paper analyzes and compares number of pumps, pump kW/ME MCR, pump kW/GE kW under the conditions of seagoing and berthing according to ship's type.

우리나라 현대 글로비스사는 스웨덴의 Stena 해운사 소속인 M/T Stena Polaris호를 용선하여 화물(납사, 43,838톤)을 싣고 2013년 9월 15일 러시아 Ust Luga항을 출항하여 약 8,100마일 북극해 항로(North Sea Route)를 통하여 10월 17일경 여수 사포 1부두에 입항할 예정이다. 이는 금년 5월 15일 "북극해 이사회"의 영구옵서버 자격을 취득과 더블어 새로운 물류 시대의 개막이라고 할 수 있겠다. 이런 시점에서 한국해양수산연수원은 국내 Ice Navigator 교육시장 선점과 세계적 교육기관으로 도약을 하기 위하여 교육과정을 개설준비 하고 있으며, 금번 시범운항 행사를 위하여 방문한 9월 13일 Ice Navigation Training 교육과정이 이미 개설되어 있는 Russia Admiral Makarov State Maritime Academy측 총장 및 관계자와 Russia교수진의 협력 및 NSR 통과 선박의 승선실습을 요청하였으며, 교육인증을 위한 협력도 추진하기로 하였다. 따라서 현재 북극해 항로현황과 Ice Navigator교육과정 개발에 대하여 검토해 보고자 한다.

Due to the complexity of underwater acoustic channel, signal estimation in underwater acoustic communication field is considerably affected from time-varying multipath fading channels. On this reason, the original signals should have many long training signals to estimate the channel and the purposed signals, and the bit rate of signals having information may have small rate. In order to avoid this loss of efficiency in underwater communication, this paper employed a blind channel identification method which don't use training signals. Simulations have predicted performance of the employed method in multipath environment and an aquatic plant experiment has verified the simulation results.

The purpose of this study was to evaluate the effects of CPR education programs on seafarers and the retention period of the knowledge. The subjects of this study were 40 seafarers who took safety training courses at the Korea Institute of Maritime and Fisheries Technology. The seafarers were tested for their knowledge and attitude before, immediately after, 1 month after, and 3 months after the CPR education program. Data were analyzed for frequency, percentage, ${\chi}^2-test$, and t-test, and ANOVA was measured repeatedly using an SPSS statistical program. Knowledge, attitude, and performance ability were significantly increased post-education as compared to pre-education. Knowledge, attitude and performance ability were consistent when tested after 1 month, but knowledge, attitude, and performance ability were significantly decreased when tested three months later. Therefore, to maintain knowledge, attitude, and skills in performing CPR, appropriate renewal times are necessary in regular seafarers' safety training centers and sailing vessels.

In this study, AHP analysis was conducted through a survey that was organized by 9 job categories. The results show that sustainable operation risks have the highest priority level among all criteria with management interest having the highest priority level within sustainable operation risks related attributes. The most important risk attributes among stakeholder risks appeared to be asset security and cargo and conveyance security, with education and training being the most important among regulatory risks. Effective management and response to the risks from export controls on strategic trade require an understanding of supply chain security and compliance programs, effective training programs, investments for development of security systems that meet international standards. In addition, the government needs to focus on developing professionals and providing support for companies with compliance programs, working closely with businesses.
