This study is currently giving priority to developing the ship's ballast water treatment system using ozone (Ozone BWTS). The Ozone BWTS was tested in a full scale land-based mobile barge to evaluate performance according to the IMO G8 Guidelines. Test cycles using the mobile-barge were conducted in seawater and brackish water in the vicinity of the Port of Busan and Nakdong River, Republic of Korea. All tests were conducted according to the requirements of the G8 Guidelines. Test results show that the Ozone BWTS meets the Ballast Water Performance Standard contained in Regulation D-2 of the IMO Ballast Water Management Convention, as well as all of the operational, safety, and environmental testing requirements of the G8 Guidelines, as required for type approval of IMO. The study results show that the Ozone BWTS is capable of meeting the Ballast Water Performance Standard under Regulation D-2 of the International Convention for the Control and Management of Ships’ Ballast Water and Sediments, and also the more stringent standards being proposed under US legislation.

Treatment of Emulsion is very important to development of Bilge Separator for new IMO Regulation. It is too difficult to demulsify the emulsion in the bilge waste water, so we use chemical treatment to break emulsion stability. Broken oil particle is treated by flotation. Bilge Separator on the Ship doesn't have enough time to treat Bilge waste water because of small space in the ship. For the solution to this problem, we experiment to find primary factor as coagulator, pH, and amount of coagulator. As the basis of test, we decided coagulator, pH and quantity of coagulator.

This study examined the background of IMO environmental regulations and countermeasures of domestic and foreign liner shipping companies and also analyzed the additional cost and profitability of container shipping companies by implementation of IMO 2020, when the fuel oil is converted to low sulfur oil. The results show that the national flag carrier would incur significant additional costs when using low sulfur oil, which would worsen its profitability in all scenarios. These analysis results suggest that for regional shipping companies need reasonable BAF setting standards, which is flexible to the price of fuel oil and also seek ways to co-exist through mutual cooperation among oil refiners, shippers and shipping companies.

There have been many accidents of passenger ships on the sea and they have caused a big loss of human lives. Maritime Safety Committee(MSC) of International Maritime Organization(IMO) made evacuation analysis of Ro-Ro passenger ships mandatory in order to save as many lives as possible at the time of accident. But this is a temporary regulation and HSC/IMO ties to introduce a performance-based regulation to improve the effect of regulation. Simulation-based evacuation analysis is the basis of performance-based regulation. In this paper, we performed a simulation-based evacuation analysis on a passenger ship, which is usually used in the plying between land and islands in Korea, with EXODUS system. Through inspecting the results from this analysis in more detail, we can make a proposal to improve the safety of passenger ship. Finally we describe the features of IMEX(Intelligent Model for Extrication Simulation), a new evacuation model being developed in KRISO.

IMO(International Maritime Organization) is strongly proceeding with adoption of a new maritime environmental convention and coming into effect for regulation enhancement about the pollutants which are happened in a ship recently. Study about the conventions that our country currently comes into effect, and there is during forwarding and correspondence must be performed effectively. In this paper, International convention on the Ballast water management a manin pending problem in ocean related environmental regulation convention.

Air pollutants from a small marine diesel engine are increasing and the IMO(International Marine Organization) regulation asked for its reduction. In this study, NOx reduction technologies such as improvement of various cooling systems are applied to the small marine diesel engine. The various cooling systems are a intercooler, a heat exchanger for engine coolant, and an exhaust manifold by water cooling. These systems are tested on an engine dynamometer and a exhaust gas analyzer by a marine diesel engine test regulation. Test results are shows that the small marine engine are satisfied the IMO NOx regulations; Tire II.

The illegal, unreported and unregulated fishing can be properly regulated only if fishing activities, transhipment and landing of illegally caught fish, and processing of fish at sea involved in it are integrally managed. To do this, flag States, port States, coastal States, market States and relevant regional fisheries management organizations shall closely cooperate. In addition, fishing boats involved in IUU fishing often ignore requirements of safety of navigation so that they could be exposed to more causes of incidents and could have less chances to be rescued. Then, it seems to be necessary for the regulation on IUU fishing to include a certain consideration of strengthening safety of those ships. International Maritime Organization(IMO) has developed and implemented international rules for the safety of shipping. IMO has cooperated with Food and Agricultural Organization on IUU fishing since 2000 and the third joint meeting is scheduled in November 2015. This paper reviews the recommendations adopted in the previous meetings, and the measures actually taken as a result of the cooperation and, in particular, focus on the additional roles of IMO for the eradication of the IUU fishing.

During the past several decades, the development of the maritime policy have been focused on the level of regulation based on the lessons from the individual accidents. Recently, the development of IMO e-navigation strategy has been discussed actively and has been focusing on the new frame and architecture based on the user requirements and definition of function and services for user requirements, which might produce the user-friendly policy, infrastructure and user service. For the new maritime ICT policy getting fusion of ICT and innovation of ship/ocean industry, the overarching methodology, as IMO e-navigation strategy, should be applied to primarily setup the architecture from the user requirements to technology. In this paper, we analyze the IMO e-navigation strategy procedure and provide the consideration and lessons for the strategic methodology to develop a new maritime ICT policy.

Along with unification world market, marine transportation has become important for international community. At the same tome, piracy, armed robbery and maritime terrorism which threaten marine transport have been issued in international society. International organization like a IMO has continued to regulate maritime crimes by international law and regulation. Bearing in mind the in importance of the issue, this article analyze maritime crimes covering piracy, armed robbery and maritime terrorism about definition and legal character and pointed out problems. Finally it suggest methods to enhance international regulation on them.

According to the NOx level requirement of annex Vl to IMO(International Maritime Organization) MARPOL 73/78, this regulation shall apply to each diesel engine with a power output of more than 130 ㎾ which is installed on a ship constructed and undergoes a major conversion on or after 1 January 2000. It is inevitable to adopt IMO standard for marine engines. Therefore, most of diesel engines which are being currently built should be tested and surveyed in accordance with the NOx technical code. In this study, various technics of NOx reduction methods were investigated for the diesel engines and the methods of NOx measuring were introduced by the new and simplified field detecting equipment. These results can be utilized for the basic design and developement of diesel engine for NOx reduction.
