Abstract

Risk Assessment is a systematic approach in assessing hazards which provides an objective to measure the hazard and allows hazards to be prioritized and compared. Risk assessment is undertaken to determine the likelihood of injury or damage to be caused by the hazard. Physical unwanted hazards that cost millions of money and lives are likely to occur in any assets if the level of risk is not analyzed and assessed. Before safety can be implemented, the level of risk involved must be determined. This final project has been carried out on the untrenched subsea gas pipeline owned by Amerada Hess Export Limited (Indonesia -Pangkah) at zone III. The risk assessment was carried out for the impact of the sinking vessel on the pipeline under loose control conditions using DNV RP F 107. Event Tree Analysis (ETA) and DNV RP F107 were used as tools to determine the risk level. After the risk level has been known, three technical mitigation methods were designed and their material and installation costs were analyzed. The three technical methods include Submat Flexiform Concrete Mattress, U Type Pre- Cast and Massive Mess Pre-Cast Methods were analyzed based on material and installation costing as the U Type Pre-Cast Method was preferred best alternative forgone and applicable.
