Pipeline Leak Detection System (PLDS) is a hardware and/or software-based monitoring tools that is utilized to indicate a leak or hydrocarbon release along the pipeline. However, it is noted that most pipelines are not equipped with PLDS as risks associated with the pipeline are mitigated by other means or deemed low. Another issue is that the current leak detection technology is not a full proof system i.e. it may still be giving false leak alarms or inaccuracies in the leak location. PETRONAS Procedures and Guidelines for Upstream Activities (PPGUA) calls for installation of Subsea Safety Isolation Valve (SSIV) for protection and risk mitigation measures to the new pipeline installed, particularly for gas pipelines or where pipelines are connected into major trunk pipeline systems with large connected inventories. A justification shall be provided if SSIV are not installed. A risk assessment study and cost benefit analysis should be performed to justify the use of PLDS and installation of SSIV. High risk pipelines such as those transporting volatile, corrosive, flammable or toxic fluids in significant volume in high consequence areas may benefit from the use of PLDS and SSIV in limiting the inventory leaked to the environment and the resulting consequence. PETRONAS Technical Standard (PTS) specifies that the requirement for PLDS and SSIV for new pipelines is to be determined via a semi-quantitative Risk Assessment or a fully Quantitative Risk Assessment (QRA). |
