Flow will be restricted to 2100 kl/h for HSD and 2000 kl/h for MS. Proposed pipeline is to be made of carbon steel having thickness of 9.54mm and Roughness of around 35-40 microns (As per PNGRB). Battery limit pressure and temperature to be around 11kg/cm2G and 40 degC. Pipeline will be provided with 3 LPE External coating and MOV’s. One pipeline for transporting of ATF has also been proposed for future on the same route.
The quantitative risk assessment for the pipelines were done and as per the study additional risk control measures required for the pipeline were recommended.
