MAOP Addressed At Mears Seminar
There are purpose-built tethered inspection systems and “tether optimized” ILI systems, and all can be configured to provide the type of information companies are looking for on their pipelines. Tethered ILI systems meet the API 1163 standard, which provides requirements for qualification of in-line and tethered inspection systems; ANSI/ASNT ILI-PQ, which establishes the minimum requirements for qualification of inspection personnel; and NACE Standard RP0102-2002, which outlines a process of activities that ILI vendors and pipeline operators can use to plan and execute a successful inspection project.
INGAA action plan
Bob Travers, Director – Pipeline Integrity for Spectra Energy Transmission, gave an overview of the “INGAA Action Plan to Build Confidence in Pipeline Safety.”
The plan commits members to a goal of zero incidents, a safety culture, a relentless pursuit of improving safety by learning from the past and anticipating the future, applying integrity management principles on a system-wide basis, and to engage all stakeholders to help them understand and participate in reducing risk.
There are nine steps in the plan. The first is to apply risk management principles beyond high consequence areas. The goal is to continue to expand the program over the coming years to ultimately cover 100 percent of the population within the PIR by 2030. Again, the second step is to raise the standards for corrosion anomaly management by applying the same HCA standard to areas outside the HCAs.
Step three is to demonstrate fitness for service on pre-regulation pipelines. This involves validating records and MAOP for pipelines in HCAs that pre-date federal regulation. If records are inadequate, they need to be assessed and the situation remediated.
The next step is to shorten pipeline isolation and response time to one hour in the event of an accident. This involves remote control valves and/or auto close valves. Improving communications and coordination with emergency responders is another one of the steps of the plan.
Improving integrity management communications and performance data and translating this into meaningful industry information and communicating it to stakeholders is the next step. The remaining ones are to implement the pipelines and PIPA guidance; evaluate, refine and improve threat assessment and mitigation; implement management systems across INGAA members and to provide forums for stakeholder engagement and emergency officials.
