From January 1, 2020, the International Maritime Organization has implemented a global regulation, known as IMO 2020, to reduce the sulfur content in fuel oil of ships from 3.5% to 0.5%. In this study, we used data from air monitoring stations to evaluate the change in air quality at New Port and North Port in Korea areas after the regulation was implemented. The concentration of SO₂ and NO₂ was higher in the port areas than in the surrounding areas due to exhaust gas from ships and vehicles. However, the SO₂ concentration decreased by more than 50% in the port area, demonstrating the efficiency and positive effect of the IMO 2020 sulfur limit.

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.

IMO developed VIMSAS for effective application of IMO instruments related to maritime safety and environmental protection and was implemented from 2006 to 2016. Based on this, the purpose and procedures of VIMSAS applied to IMO member states by trial, and IMSAS was enforced from January 1st 2016. IMSAS was implemented to ensure that IMO Member States, such as flag states, coastal states and port states that ratified the IMO Convention, are properly performing their given responsibilities and to ensure the effective implementation of the IMO instruments through the improvement of identified non-conformities. In this study, the auditing contents and procedures were verified based on IMO documents in order to prepare for the IMSAS audit of Republic of Korea scheduled for 2020. For this purpose, this study proposed an update of a directory, development of monitoring system for information reporting required by IMO instruments, designation of relevant experts, preparation of an English version of related national laws, training of IMSAS auditors and establishment of an IMSAS audit response team for audit of IMSAS in 2020 by referring to the results of the VIMSAS for Republic of Korea, major findings of the VIMSAS of other IMO member states, and Consolidated Audit Summary Report (CASR), which was submitted at the 5th IMO III sub-committee.

국제해사기구(International Maritime Organization, IMO)에서 해양안전과 환경보호를 위해 국제규범들을 도입 및 시행 중에 있다. 그러나, 크고 작은 해양사고는 지속적으로 발생하고 있으며, 인명사상, 환경오염을 유발하는 심각한 선박사고는 꾸준히 발생하고 있다. 이에, 인적요인 역할 강화를 위해 IMO에서는 선원교육훈련 지침의 개발을 결정하였다. 본 연구에서는 동 지침의 개발을 위한 주요 고려사항들과 해양사고사례에 얻은 교훈의 효과적인 활용을 위해 IMO의 다양한 인적요인관련 국제지침들과 교육 요령 등을 분석하여, 적절한 교육기법 및 프레임워크를 제시하였다.

자율운항선박의 등장으로 국제해사기구는 기존 IMO 협약의 개정사항 식별이나 관련 국제협약의 통일해석과 제개정이 필요한 사항을 논의하고 있다. 제105차 법률위원회에서는 MASS 규정식별(RSE) 작업에 대하여 2022년 완료를 목표로 제106차 법률위원회부터 논의하기로 결정한 바 있다. 이와 관련하여 MSC RSE 작업결과와 방법론 개발을 통하여 자율등급, 방법론, 협약리스트, 작업계획 등을 확정할 계획이다. 우리나라에서는 헌법 제6조의 규정에 따라 국제법규는 국내법과 동일한 효력을 가지고 IMO 회원국감사제도에서 회원국이 국제협약을 국내법으로 수용하여 이행하고 있는지를 감사하고 있기에 국제협약이 국내법으로 수용하는 작업이 얼마나 중요한지를 알 수 있다. 이번 연구에서는 IMO 국제협약 RSE 작업을 기반으로 자율운항선박의 자율화 정도구분 및 기술발전단계에 다라 개정소요가 필요한 국내법을 식별하고 비교·분석하여 자율운항선박이 상용화되기 위한 새로운 법안 마련의 필요성을 제시하였다.

The IMO introduced the voluntary audit system (VIMSAS) in 2005 and conducted audits of 67 member states. The audit (IMSAS) of Republic of Korea is scheduled to take place in July 2020, and it is time to thoroughly prepare for the audit to minimize the Findings and Observations and provide best practices for the implementation and enforcement of IMO conventions to ensure safety of life at sea and protection of the marine environment. In this paper, major findings and observations were analyzed for the IMSAS audit results, which were forced into force in 2016, and a comprehensive strategy was developed based on the audit analysis results of other member countries.

In this study, we sought to establish a vessel-discharge pollutant-treatment system recommended by IMO by first investigating advanced facilities overseas to help us understand and evaluate our domestic facility and needs. IMO recommends the installation and operation of port pollutant-storage facilities to adequately treat pollutants emitted by ships entering the port, and we reviewed the registration and operation of these facilities in IMO member countries, focusing on the IIII Code. Due to recent environmental regulations, additional facilities are required to treat the washing water discharged from equipment such as scrubbers mounted on the ship so pollutant-storage facilities must be established. Currently, Korea's ship-discharged wastes are being moved from ports to land waste-treatment plants, and their quantity and properties are not being monitored. Therefore, in this study, we improved monitoring of the discharged pollutants and investigated the proper arrangement of pollutant storage facilities as recommended by IMO. The system we established can help provide smooth service to incoming ships - and appropriate treatment of pollutants and will greatly benefit international maritime operations.

UN 산하의 국제해사기구(International Maritime Organization, IMO)는 2016년 10월 24일 열린 해양환경보호위원회 70차 회의에서 2020년부터 선박에서 사용되는 연료유에 포함된 황함유량 허용치를 기존 3.5%에서 0.5% 이하로 제한하기로 결정했다. 따라서 2020년 이후부터 전 세계를 항해하는 모든 선박은 연료유의 황 함유량을 0.5% 이하로 낮춰서 운항을 해야 한다. 지속가능한 경영을 위해서 국제적 환경규제에 대응하여 각 선사의 상황에 적합한 해결책을 강구하여야

International Maritime Organisation (IMO) regulations insist on reduced emission of CO₂, noxious and other environmentally dangerous gases from ship, which are usually let out while burning fossil fuel for running its propulsive machinery. Contrallability of ship during sailing has a direct implication on its course keeping and changing ability, and tries to have an optimised routing. Bad coursekeeping ability of a ship may lead to frequent use of rudder and resulting changes in the ship's drift angle. Consequently, it increases vessels resistance and also may lead to longer path for its journey due to zigzag movements. These adverse effects on the ship journey obviously lead to the increase in fuel consumption and higher emission. Hence, IMO has made it mandatory to evaluate the manoeuvring qualities of a ship at the designed stage itself. In this paper a numerical horizontal planar motion mechanism is simulated in CFD environment and from the force history, the hydrodynamic derivatives appearing in the manoeuvring equation of motion of a ship are estimated. These derivatives along with propeller thrust and rudder effects are used to simulate different standard manoeuvres of the vessel and check its parameters against the IMO requirements. The present study also simulates these manoeuvres by using numerical free running model for the same ship. The results obtained from both these studies are presented and discussed here.

In this study, we compared and analyzed the Revealed Comparative Advantage (RCA) and Trade Specialization Index (TSI) based on ballast water management systems (BWMS) trade data, which are related to the International Maritime Organization (IMO) Ballast Water Management Convention to suggest the current status of Korea's industrial competitiveness and suggest future development directions for the BWMS industry. As international interest in eco-friendly vessels is expanding, the IMO is engaged in dramatic discussions and agreement-making related to marine emissions of pollutants from ships. IMO member states that must implement this convention are striving to develop technology and secure industrial competitiveness as major industries in the eco-friendly shipping sector, with the BWMS industry experiencing a high market entry barrier and the possibility of the leading market entrants gaining leadership. The Republic of Korea accounts for 17 (approximately 38 %) of the 45 BWMS that received final approval as of October 2019. Based on trade data relating to product codes HS842219, HS84212, and HS89, the RCA index and TSI were calculated and compared. The findings revealed that the Republic of Korea has relative inferiority compared to countries such as Germany and Denmark. Despite this, Korea's favorable industrial environment, which includes several IMO-approved BWMS technologies and the possession of domestic certification institutions, is likely to strengthen its competitiveness in the BWMS market.
