Marine casualties and environmental pollution have increased recently. Especially, the rate of incident of Coastal tankers is higher, but the assessment tool for safety management system is lack in this fields. However Oil Major Vetting System being professional assessment tool for tanker is widely applied in ocean going tanker by the worldwide Oil Majors. According to the analysis of the marine tankers' incidents which applied Oil Major Vetting System, the incidents were reduced rapidly for recent about 5 years. Using Oil Major Vetting System is helped to improve safety management and to prevent marine incidents. Therefore if applying a parts of the Oil Major Vetting Systems to the coastal tankers' Safety Management System, the Coastal tankers incidents would be reduced and improved gradually.

최근들어 육상의 인간 활동에 의한 다량의 오염물질 부하에 기인하여 연안에서 심각한 환경 문제가 발생하고 있다. 따라서 해양 생물체 이용 시스템이 육지와 해양간의 물질 순환을 시도하기 위하여 제안되었다. 포괄적인 평가는 제안된 시스템이 적절하고 지속가능한지를 밝힐 필요가 있다. 본 연구는 에너지의 질을 표현하고, 물질 순환 시스템에서 흐르는 물질과 에너지를 묘사하는 열역학적 개념의 엑서지를 도입하였다. 본 연구는 일본 오사카 중부에 위치한 사카이시의 물질 순환 시스템 내에서 물질, 에너지, 그리고 엑서지 흐름들을 제공한다. 엑서지는 엑서지 효율적인 물질 순환 시스템 내에서 무엇이 주요 역할인지 잘 이해하는데 도움을 주는 것으로 밝혀졌다.

Marine casualties of fishing vessels were analyzed to reduce the sacrifice of human life using data of the Korean Maritime Safety Tribunal from 1995 to 2004 in Korea. The occurred number of fishing vessel casualties were likely to be higher portion than non-fishing vessels, but the occurring ratio of fishing vessel casualties were marked 2.96 times lower than that of non-fishing vessel casualties. The occurring ratios of bigger fishing vessel casualties were higher than smaller ones. Most marine casualties were resulted from the human factors such as poor watchkeeping, negligent action for engine and etc. The trend of marine casualties showed that the machinery damage hold the first and collision accidents took the second, but on a point of cause of them, operating errors took first and poor handling or inspection of machinery held the second place. Because those two casualties took major portion, and very important problems for safety of fishing vessels, so we ought to try to reduce the factors before everything else. In addition, since collision, sinking and capsizing in marine casualties have led to death, missing and injury of lives, it is necessary for navigation operators to take more educations and training intended to reduce the marine casualties systematically and continuously.

울산항은 제1항로와 제2항로, 제1항로와 제3항로의 분기점에서 해상교통흐름이 교차하고 있고, 1항로접근수역 및 관절곶 해역에서 교통흐름이 교차하고 집중하고 있다. 또한 현재 49선석에서 2011년 29개 선석의 추가개발로 수역시설에 대한 조정 등이 필요할 것으로 판단된다. 본 연구에서는 울산항 인근해역에 대한 자연환경, 해양사고, 해상교통량 및 해상교통흐름 관측, 어업현황 등을 조사 분석하고, 전문가 및 이용자에 대한 설문조사를 실시하여 개선안을 도출하고자 한다.

Efficient control of a marine engine requires an engine control unit (ECU) system that handles fast and precise signal processes for in-coming and out-going signals from fast running engines. In order to handle these roles, the sequential control has been adapted in the ECU system in small and medium size ship engines, which has caused high production cost and complexity of the system. Hence, this paper is focused on developing an distributed ECU system for high speed and high precision control of a marine engine by efficiently combining a CPLD chip and a microprocessor. By sharing load at the MCU with the designed CPLD chip, we could achieve in driving a marine engine with high speed and precise control so that the ECU board has been simplified and its production cost has been reduced.

In this study, we have developed the high resolution multichannel seismic data acquisition system and shallow marine seismic source. It is easy to operate our source system which utilizes piezoelectric transducer of high electrical power. According to water depth, survey condition and purpose, transducer number of source system can be easily changed in order to maximize field applicability. In the recording part, we used 24 bits and 8 channel high speed A/D board in order to achieve the improvement of data quality and the efficiency of data acquisition. The developed system was tested and varied with the data acquisition parameters such as source-receiver offset, and transducer number versus water depth for the field application.

It is necessary to develop highly sophisticated Modeling & Simulation (M&S) system for the scientific investigation of marine accident causes and for the systematic reproduction of accidental damage procedure. To ensure an accurate and reasonable prediction of marine accidental causes, such as collision, grounding and flooding, full-scale ship M&S simulations would be the best approach using hydrocode, such as LS-DYNA code, with its Fluid-Structure Interaction (FSI) analysis technique. The objectivity of this paper is to present three full-scale ship collision, grounding and flooding simulation results of marine accidents, and to show the possibility of the scientific investigation of marine accident causes using highly sophisticated M&S system.

This study analyzed the offshore plant industry and related regulations such as ISO, IEC, and Norsok Standards to develop an integrated network management system (INMS) capable of both on-site and remote management and configuration of IP-based network equipment in offshore plants. The INMS was designed based on actual specifications and POS plans, and a plan of management was verified through an offshore plant engineering company. Various modules such as PAGA interface modules, CCTV, IP-PBX, and HF-radio communication modules were developed for system implementation. Protocol and data design and screen design were followed by framework development and introduction of the automatic satellite communication function.
