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.
