The Protocol adopted in Sep. 1997 included the new Annex VI of MARPOL 73/78, which entered into force on 19 May 2005. Revision for the accept MARPOL Annex VI with make public on 29 Dec. 2005 and enforce on 29 Jun. 2006. For all that not installation at oil terminal or if installed do not used. The purpose of this study is to research and evaluate the methods of sampling and analysis, and the pollution measure of existed VOCs during the bulk liquid cargo operation at vessels. As the sampling instrument of VOCs, Tedlar bag has the effect of decrease in concentration by the chemical reaction and absorption, and the method using the solvent extraction has error cause because of the extraction, the absorption tube has error by the breakthrough. But canister is the best sampling instrument because of having no sampling mistake. The study on VOCs emission is not sufficient for the research on the pollution cause and the analysis data on the HAP during the bulk liquid cargo operation at vessels. Hence, monitoring on the management hazardous VOCs need to be continued during the cargo operation at vessels and VOCs management field must be study for the make progress at a good pace for reason of crew's health.

The Protocol adopted in Sep. 1997 included the new Annex VI of MARPOL 73/78, which will enter into force on 19 May 2005. MARPOL Annex VI sets limits on sulphur oxide and nitrogen oxide emissions from ship exhausts and prohibits deliberate emissions of volatile organic compound (VOCs) from oil tanker in port and oil terminal. This study was conducted to find out countermeasures for the new Annex VI of MARPOL 73/78 and draw up a feasible management plan. The emission quantity of NOx and SOX from ships in Ulsan Port was calculated by U.S. EPA and Japan Marine Engineering emission factors of air pollutant from ship exhausts. In addition, volatile organic compound (VOCs) from oil tanker during the loading and discharging period, also calculated.

As of Jan. 2006, numbers of korean registered ocean-going vessels reached 546 which amounted to 13,716,733 G/T. Vessels, generally spooking, finish her life cycle and are dismantled or recycled. However, most of these activities have been done in undeveloped countries instead of in developed countries as the environmental restrictions in developed countries get more strict, accordingly international bodies adopted shipbreaking-related guidelines and prohibit transboundary of obsolete ships, taken as one of wastes. The authors made the Working Guidelines on Shipbreaking to cope with substandard working environment and reduce the environmental damage, and came up with a method to make a inventory of hazardous materials for effective control, finally framed a draft of Environmentally Sound Ship Recycling examining related international conventions such as Basel Convention, IMO Guideline, ILO Guideline and IMO new Convention(draft) on shipbreaking and recycling.

세계경제는 인류의 지속가능한 성장을 위해 2020년을 기점으로 저탄소 경제체제에서 무탄소(에미션 제로·Emission Zero) 경제체제로 변화를 꾀하고 있는 상황이다. 이러한 변화는 해운분야에서도 예외가 아니다. 국제해사기구에서 선박온실가스 규제라고 할 수 있는 에너지효율 규정이 해양오염방지협약 부속서 6의 제4장(에너지 효율관리)으로 2011년 개정·채택된 것을 시작으로 최근 2030년까지 40%감축, 2050년까지 50% 감축이라는 온실가스 감축목표를 설정하여 본격적인 온실가스 감축을 위해 노력하고 있다. IMO는 감축목표를 달성하기 위한 단기조치, 중·장기 조치를 2023년까지 완성한다는 목표를 설정하고 장애요인 분석, 국가별 영향평가, 역량강화 및 기술지원과 연구개발에 관한 로드맵을 포함한 최종 전략 수립을 진행하고 있으나 문제는 국제해사기구(IMO) 2030 온실가스 감축목표 달성은 현재 사용되고 있는 화석연료로는 불가능하기 때문에 선박추진 연료로써 수소, 연료전지, 메탄올 등 대체에너지 개발을 대폭 지원하는 국가의 정책전환이 시급하며 이를 구체화할 수 있는 정책개발이 시급하다.

The electric propulsion development is underway to minimize pollutants and greenhous gas emissions during the operation of ships / offshore installation vessels. The importance of the use and efficient management of batteries, which is an ESS system in ships / offshore installation vessels, is increasing. Generally, in ESS where battery is applied, cell balancing and life span are monitored in real time by BMS. Ships / offshore installation vessel are equipped with several ESS rooms, and ESS rooms with ESS systems of the same specification are being constructed due to the recent demand for electric propulsion development. In this paper, we propose an algorithm to additionally predict and diagnose battery pack and cell balancing failures by comparing BMS data for each rooms. The proposed algorithm compares the BMS data of each ESS Room according to the environmental change of the ship / offshore installation vessels, measures accurate status information, and reliably monitors it to prevent accidents in advance.

Guidelines on ship recycling are adopted internationally. UNEP adopted 'Basel Convention', providing Environmentally Sound Management(ESM) of facilities and recommendations. IMO adopted 'Guidelines on Ship Recycling', providing measures for worker's safety, how to control pollutant materials and the meaning of 'Green Passport'. IMO Convention (draft) is in progress. ILO adopted ILO Guideline', providing how to make sure safety and health for workers in shipbreaking. But Republic of Korea goes against the stream and there is much to be desired. At this point of time, we carried out a study on international trend regarding ship recycling, a plan to cope with international trend, and it is considered to be necessary to establish a special law on ship recycling.

Recently, water shortages have occurred due to climate change, and the need for water management of agricultural water has increased due to the occurrence of algal blooms in reservoirs. Existing algae prevention is operated by putting many people on site and misses the optimal spraying time due to movement through boats. In order to solve this problem, it is necessary to block contamination in advance and move within time to uniformly spray complex microorganisms uniformly. Control drones are used for pesticide spraying and can be applied to algae prevention work by utilizing control drones. In this paper, basic research for the establishment of a marine control system was conducted for application to the reservoir environment, and as one of the results, the characteristics of a drone nozzle, a core technology that can be used for control drones, were calculated. In particular, it was found that the existing agricultural control drones had a disadvantage that the concentration was non-uniform within the suggested spraying interval, and to compensate for this, nozzle positioning and nozzle spraying uniformity were calculated. Based on the experimental results, we develop a core algorithm for establishing an algal bloom monitoring system in the reservoir environment and propose a precision control technology that can be used for marine control work in the future.

In order to elucidate the current state of marine pollution of heavy metals around major shipyards in Korea, seawater samples were collected at eleven sampling stations and four control stations around 4 major shipyards located in the southeastern coast of Korea in summer 2010, and 6 kinds of metals such as copper(Cu), zinc(Zn), iron(Fe), cadmium(Cd), lead(Pb) and mercury(Hg) in seawater samples were analyzed. The analyses of heavy metals in seawater showed that the mean Cu concentrations in seawater around 4 major shipyards were in the range of $0.817{\sim}1.638{\mu}g/L$ which were lower than Korean environmental standards of $20{\mu}g/L$ for the protection of human health(PHH) and of $3{\mu}g/L$ for short-term protection of marine ecosystem(SPME) but higher than Cu concentration at control station by a factor of up to 2.75. The mean Zn concentrations were in the range of $0.228{\sim}0.567{\mu}g/L$ which were lower than Korean environmental standards of $100{\mu}g/L$ for PHH and $34{\mu}g/L$ for SPME but higher than Zn concentration at control station by a factor of up to 5.91. The mean Fe concentrations were in the range of $3.332{\sim}7.410{\mu}g/L$ which were higher than Fe concentration at control station by a factor of up to 6.75. The mean Cd concentrations were in the range of $0.013{\sim}0.028{\mu}g/L$ which were lower than Korean environmental standards of $10{\mu}g/L$ for PHH and $19{\mu}g/L$ for SPME but higher than Cd concentration at control station by a factor of up to 2.33. The mean Pb concentrations were in the range of $0.007{\sim}0.126{\mu}g/L$ which were lower than Korean environmental standards of $50{\mu}g/L$ for PHH and $7.6{\mu}g/L$ for SPME. The mean Hg concentrations were in the range of $0.002{\sim}0.004{\mu}g/L$ which were lower than Korean environmental standards of $0.5{\mu}g/L$ for PHH and $1.8{\mu}g/L$ for SPME. Although the concentrations of metals such as Cu, Zn and Fe which were used in shipbuilding works were lower than Korean environmental standards for PHH and SPME, the fact that the concentrations of Cu, Zn and Fe at sampling stations around major shipyards were higher than those at control stations implies that the works in shipyards had some effects on marine water quality around shipyards. Therefore, marine environment management such as the prevention and control of the discharge of various pollutants from shipyards is required on national level.
