| Abstract | Petroleum is typically essential to numerous industries, and is of significance to the maintenance of industrialized civilization itself, and therefore is vital to various nations. Petroleum products are highly demanding, to meet that such, a lot of offshore oil and gas installations have been constructed in order to produce oil and gas on the road to fuel our commodity. The high demand of petroleum products resulted in the expansion of offshore installations, both subsea pipelines and offshore platforms, all over the world. At the ending of their economic production lives, there is the requirement from the government that all subsea pipelines have to be decommissioned in order to make certain of safety to navigation and to care for the right of other users of the seas. Currently, there are more than 1000 km. of subsea pipeline has been installed in the Gulf of Thailand, their life already exceeded 20 years and some of them have to be abandoned by now. At the moment, there are some studies regarding offshore platform decommissioning in the Gulf of Thailand (GOT), however there is no any existing study on the subject of subsea pipeline. Therefore, this investigation study is concluded to select the best suitable subsea pipeline decommissioning option. The outcomes of this study are expected to contribute to the decommissioning activities in the Gulf of Thailand. This can be taken into consideration by stakeholders, government and public on the decommissioning option and its impact to environment. To study this, hazard identification (HAZID) is firstly performed in order to prepare for risk precaution and mitigation. Then, risk evaluation will be performing by fault tree analysis (FTA). After that, the approximated cost will be assessed; this is the most crucial part as it is really costly to complete decommissioning activities. The study found that the leave-in-place, "leave on seafloor" is the most practicable subsea pipeline decommissioning option. The result may be utilized by the governmental organizations, contractors or operators to further develop subsea pipeline decommissioning guideline. |
