| Abstract | Thailand oil and gas industry has been established for over 30 years and successful in exploration and production of the natural resources. Currently, there are over two hundred fixed offshore platforms installed in the Gulf of Thailand and some of them are reaching the end of their economic production life. Therefore, this research will be high advantage for Thailand to prepare decommissioning activities in the near future. The research was studied in risks for offshore platform decommissioning activities and the ways to assess risks and approximated cost. Currently, there has been no decommissioning to perform in the Gulf of Thailand since the reservoirs have not yet been reached the economic life. Moreover, there is a lot of reluctance from all stakeholders. The reason is a complexity of that such activities and the lacking of experienced operators. The goal of this research is expected to make a contribution to select the most suited platform decommissioning option in the Gulf of Thailand. The cost and safety, environmental impact, have been contemplation by related parties, government and non governmental organization on the platform decommissioning options. The top three decommissioning options are come up from the BPEO screening options in order to consider in term of operational safety and cost. Beginning with qualitative risk assessment, the hazard identification (HAZID) is initially utilized so as to set up for risk precaution and mitigation. Furthermore, risks evaluation will be assessed by fault tree analysis (FTA) breakthrough cost of failure and probability of failure. Subsequently, the platform decommissioning cost will be estimated based on the major activities. Moreover, this portion is the most critical section from concessionaire point of view. The best practicable platform decommissioning option in the Gulf of Thailand was the topple¬(tow)in-place because there was no impact to environment while operating cost and cost and risk ratio were low. It has been win-win situation for both government and concessionaire. |
