  • Recently, LNG receiving terminals have been widely constructed and expanded for an increase in LNG demand. Selection of the storage tank for send-out and estimation of send-out flow rate have significant influence to process operation and economics. In this study, a send-out flow rate of each storage tank is optimized in order to minimize the total BOG generation rate. Considering a size and characteristic of each storage tanks, BOG flow rates are estimated using a dynamic simulation with varying liquid levels in the tanks. The regression model is developed fitting BOG flow rates and tank liquid levels, which are boil off rate model to predict BOG flow rates with particular level data. The objective function and constraints including required total send-out flow rate and level limit in the tanks are formulated to optimize a send-out flow rate of each tank. This method for optimization of send-out operation is applied to the Incheon LNG receiving terminal considering two scenarios for various liquid levels and maximum and minimum required send-out flow rates. For maximum required send-out flow rate, this method achieves BOG reduction of 9% comparing with assumed conventional operation.

  • With increasing uncertainty of energy market in the world, the policies for the energy resource security have become crucial Several countries with poor energy resource like Netherlands and Singapore have pursued the policy for becoming an oil hub in the region. Singapore has been an oil hub in East Asia for a long time not only because it is well located with a large number of countries exporting and importing oil but it has also pursued strong policies to become an oil hub while establishing favourable institutional, regulatory and business environment for accommodating major refineries and petro-chemical companies. However with growing trading volume of petroleum products in Northeast Asia and a record high price of oil in these days, the necessities of another oil hub in the region are considered in order to reap benefits of the security of economical and stable oil. South Korea is situated astride the main North Pacific shipping route, with deep water ports and proximity to Chinese and Japanese industrial centres that make tank terminal operators Ideal choices for the oil hub in Northeast Asia although it has several disadvantages such as lack of independent storage facilities, underdeveloped oil trading market and unfavourable business friendly climates etc. This study is focused on examining the globalization strategies of tank terminal operators such as Vopak, Oiltanking and Odfjell in order to suggest the policy implications for becoming an oil tub in Northeast Asia.

  • 전 세계적으로 천연가스의 수요가 급격하게 증가함에 따라 천연가스의 생산 및 공급이 활발하게 이루어지고 있고, 향후 10년 간 천연가스의 사용량이 현재의 2배 이상이 될 것이라는 추측도 나오고 있다. 이에 따라 천연가스 생산지에서는 천연가스 액화 플랜트(Liquefaction Plant)와 저장 탱크(LNG Storage Tank), 수입하는 곳에서는 재기화 플랜트(Regasification Plant)와 저장 탱크, 그리고 LNG를 운송할 LNG 운반선의 신조프로젝트가 활발하게 진행되고 있다. 미국의 경우 911테러와 NIMBY 사고의 확대로 인하여 LNG 수입기지의 육상건설을 주민들의 반대하자 해상에 건조하려는 경향을 보이고 있으며, 이에 따라 여러 가지 형태의 LNG Offshore 터미널이 설계되고 있다. 향후 LNG의 급격한 수입이 예상되는 나라로는 미국, 중국, 인도 등이 있으며 수출국으로는 카타르가 급격하게 부상하고 있다.

  • Domestic harbor yard storage facilities are a place specifically located in a container terminal for import and export of packaged dangerous goods, and due to the recent relaxed criteria for the secured open area, concerns for the extended damage upon accidents are increasing. In this study, the impact of damages by radiant heat was analyzed through a simulation of a pool fire caused by the leakage of flammable liquids from a tank container. As a result, it was analyzed that the distance of radiant heat according to threshold damage levels was beyond the current criteria of the secured open area, and the structural damage of adjacent containers could happen within a very short time if they were exposed to the early pool fire continuously. It is considered that this study will be helpful in preparing the proper criteria for the secured open area between yard storage facilities in a container terminal.

  • 1960년대까지는 저팽창단백포가 유류화재의 진압에 주로 사용되었으니 불소화합물 계면활성제로부터 유출된 합성 AFFF를 개발하면서 해수로도 이의 사용이 가능하고 지역 및 유출화재 예방에서 AFFF 특유의 초기진압효과 및 대형화재를 방지한다는 장점 때문에 널리 사용되고 있으며, 석유화학산업의 저장탱크지역 및 공정지역에서 AFFF와 FPF가 주로 사용되며 부두시설(Oilrig, Marine Tanker, 해상 / 해변터미널)에는 AFFF의 사용이 지배적이다. 현재 사용되고 있는 foam으로는 단백포(Protein: PF), 불화단백포(Fluoroprotein: FPF), 막형성 불화단백포(Film Forming Fluoroprotein Foam: FFFP), 고팽창폼(High Expansion Foam), 수성막 형성폼(Aqueous Film Foaming Foam: AFFF), 알콜폼(Alcohol Resistant Foam: ATD) 등이 있으니 본고에서는 AFFF 중심으로 소개한다.

  • In the Northeast Asian region, including Korea, China, and Japan, with rapid economic growth since the 1990s, intra-regional oil logistics has been increasing. Under such external circumstances, Korea has been pursuing a policy to become a Northeast Asian petroleum logistics hub since the mid-2000s. In order to become a Northeast Asian logistics hub, it is important to establish and promote a business model to promote the value-added oil logistics business. This study aims to propose policies and practical implications for increasing petroleum logistics by analyzing Korea's petroleum logistics business model in Northeast Asia. The results of case analysis through interviews with 23 tank terminal companies are as follows. First, most of the oil storage tank terminal companies interviewed are conducting value-added petroleum logistics such as blending, breaking bulk, and consolidation etc. Second, value-added petroleum logistics is caused by an imbalance in supply and demand among neighboring countries in Northeast Asia. In particular, there is a high demand for breaking bulk and blending connecting Japan, Oceania, the United States, and South America. Third, it is necessary to promote the promotion of value-added logistics by improving infrastructure, institutions, and regulations in response to the demand for value-added petroleum logistics, which will greatly contribute to Korea's policy for being Northeast Asian oil hub.
