A Safety Study of the Evacuation Plan of an Offshore Production Facility during Hook-up and Commissioning Phase|RISS 상세보기

다국어 초록 (Multilingual Abstract)

Objective: The aim of this study is to evaluate if personnel on board can evacuate safely in emergency during hook-up and commissioning phase of offshore production facility.
Background: As an offshore facility is operated remotely from land, the safety of operators becomes more significant when they are exposed to various hazards such as fire, explosion, ship collision and etc. Therefore, it is important to arrange available evacuation means properly and check other related elements in advance. For these reasons, evacuation analysis for normal operation phase is performed in the design stage. However, during hook-up and commissioning phase, the number of operators on board the facility could become double compared to the normal operation phase.
Therefore, evacuation analysis should be performed for this phase and evacuation means including life-saving appliances should be additionally installed to secure the safety of increased operators.
Method: Evacuation time analysis is based on defining actions and assumptions for various stages of evacuation. For time calculation, evacuation scenarios should be established first. Depending on the evacuation means, escape routes and procedures change. Then, time for each evacuation stage is accumulated to determine if time requirement could be met. The integrity of temporary refuge system is also checked if it can accommodate the increased number of personnel in emergency.
Results: Based on various rules and regulations such as IMO, ISO, ABS, and etc., the needed quantity of life-saving appliances and the integrity of the temporary refuge were checked to ensure the safety of operators prior to evacuation. Temporary refuge system can accommodate the increased number of operators. Three evacuation scenarios are established and total evacuation time of all scenarios satisfy the time requirement.
Conclusion: As the number of evacuees is a dominant factor in evacuation time calculation, evacuation during hook-up and commissioning phase when the number of operators on board dramatically increases should be separately evaluated.
Application: The results of the evacuation analysis might help to establish the evacuation scheme of offshore facilities during hook-up and commissioning phase.
