LNG 공사의 건설사업관리 의사결정지원모델 개발 - 시공단계 중심 -

Abstract

Abstract: LNG plant projects tend to be implemented in overseas owing to its characteristics, so their project management scheme is somewhat different from those of general projects. Value chain in a LNG plant project includes exploration/production of gases, physical liquefaction/chemical conversion processes, transportation and storage. Key factors in the chain include liquefaction process (including ultra-low temperature liquefaction) to convert natural gas into liquid materials or fuel, and Front End Engineering Design (FEED) package, as well as Engineering, Procurement and Construction (EPC) technology comprising control, operation and construction . Success of a complex LNG plant project implemented in overseas depends on decision-making process in project manageme nt. Accordingly, to develop a decision-making model in of plant construction, the study extracted none factors in project management by EPC stage and assessed importance of each factor. The result showed that items in both project management and project risk management are important. Especially, the study developed a decision-making model in the construction sta ge of a LNG plant project based on the project management factors and importance assessment. The developed dec ision-making model would lay groundwork in building a decision-making system in construction stage of project management.Keyword : LNG Plant, EPC, Project Management, Decision-making model, Eval uation of Importance Factor
