Interview Questions for Gas Energy Management

High-pressure and low-pressure gas distribution systems differ primarily in the pressure at which they transport natural gas. High-pressure systems, typically operating above 250 psi (pounds per square inch), are used for long-distance transmission of large volumes of gas from production sources to distribution points. These systems require robust, thick-walled pipelines and specialized compressor stations to maintain pressure over long distances. Think of them as the ‘highways’ of the gas network.

Low-pressure systems, operating below 250 psi and often closer to 1 psi at the customer’s meter, handle the final delivery of gas to individual customers such as homes and businesses. These systems branch off from high-pressure lines and utilize smaller diameter pipelines with fewer safety and pressure regulation requirements. They’re akin to the ‘local streets’ distributing gas to homes.

The difference is crucial for safety and efficiency. High-pressure systems require rigorous safety measures to prevent leaks and ruptures due to the immense force of the gas. Low-pressure systems focus on ensuring consistent and safe pressure levels for end-users.

My experience in gas pipeline maintenance and integrity management spans over 10 years, encompassing various aspects from routine inspections to emergency repairs. I’ve been involved in the development and implementation of comprehensive integrity management programs, utilizing techniques like in-line inspection (ILI) using smart pigs to detect internal pipeline flaws such as corrosion and cracks. ILI data is then analyzed to prioritize repairs and prevent catastrophic failures.

I also have extensive experience in external corrosion monitoring, employing techniques such as close-interval surveys (CIS) and soil resistivity measurements. This helps identify areas vulnerable to external corrosion and allows for preventative measures like cathodic protection systems to be implemented. We also regularly conduct hydrostatic testing on pipelines sections to confirm pressure integrity and identify weaknesses. The goal is always proactive maintenance to minimize risks and ensure reliable, safe operation of the gas pipelines.

For example, in one project we identified a significant area of external corrosion using CIS data which allowed us to schedule excavation and repair before any leakage occurred. This preventative maintenance saved considerable costs and avoided a potential environmental hazard.
