It means that the obstacles in public acceptance are less than the onshore re-gasification plant. Another advantage is the Risk assessment is a relatively new technical field and dissimilar from easiness of LNG-FSRU construction in the modern major shipyards, traditional divisions of engineering such as civil, mechanical, chemical, covering all key functions such as procurement, material supply, aero-nautical. It applies to all of them and belongs to none.

ABSTRACT: Risk assessment is a relatively new technical field and dissimilar from traditional divisions of engineering such as civil, mechanical, chemical, and aeronautical. It applies to all of them and belongs to none. Nowadays, in offshore area, risk assessment became an important item (tool) to check the rule & regulation and to verify a new design, construction way and operation activity, etc. This paper presents the severity of major hazards at initial design stage of LNG-FSRU. First of all, we did HAZID study to get every possible hazardous event that we can imagine from structural lay-out and operational activity of LNG-FSRU. Second, we tried to find major accidents and its scenarios which can cover serious or typical events (accidents) identified from HAZID study and offshore accident records. Third, a numerical analysis (consequence analysis) was carried out to evaluate the severity of each scenario including major accidents. Finally, we suggested several prevention and mitigation methods to decrease the present risk. INTRODUCTION LNG-FSRU (Floating Storage and Re-gasification Unit) is a new concept to supply a natural gas from offshore re-gasification plant to onshore consumer. It has been proposed as alternatives to traditional onshore re-gasification plants. The concept of LNG-FSRU has been studied and developed as a new LNG supply facility for a long time, caused by the FSRU concept having several benefits over the land based re-gasification facility. One great advantage is the flexibility for location with minimum or no construction at onshore. It means that the obstacles in public acceptance are less than the onshore re-gasification plant. Another advantage is the easiness of LNG-FSRU construction in the modern major shipyards, covering all key functions such as procurement, material supply, construction, mechanical completion and testing. Also the LNG-FSRU will have the benefit of being able to move other places.
