North America has the world’s largest network of gas and crude oil pipelines. Pipeline repairs can be complex and demanding, especially when dealing with challenging conditions such as difficult terrains, high-pressure systems, or aging infrastructure. Successful pipeline repair requires meticulous planning, precise execution, and adherence to best practices because getting it wrong could be deadly. In the interest of safer pipeline repairs, here are 12 tips that may be helpful.
The Importance of Pipeline Maintenance
Utilities are the backbone of U.S. infrastructure. Without a functioning web of utilities, many businesses and most communities would struggle to survive. The crucial importance of pipelines in distributing these vital, highly volatile ingredients safely is recognized and covered by regulations. These regulations are the same that require pipeline operators to ensure the integrity of their pipelines. That assurance is created through conducting preventative and regular routine maintenance and repairs, which helps prevent potential systems failures.
Even with a proactive system of maintenance and care, the United States has suffered over 3,200 serious gas pipeline leaks since 1987.
Our pipelines consistently undergo inspections using some of the most groundbreaking technology on the market. It is, however, inevitable that at some point a pipe will need to undergo repairs. There are several different repair options in current usage.
The most involved and lengthy option is to cut and extract the damaged section of pipe and then install a new section. There are two types of sleeve repair for this process, Type A and Type B. Hot tapping may also be used to repair sections of pipe which have problems that were caused by corrosion or mechanical damage. This method can also add branches for system modifications.
Repairing our pipelines is a crucial part of maintenance that keeps our utilities and resources flowing and operating smoothly.
Tips For Challenging Pipeline Repair
1. Comprehensive Assessment and Planning
Before any repair work begins, it’s always a good idea to conduct a thorough assessment of the pipeline’s condition, the nature and severity of the damage, and the surrounding environment. You can utilize technologies like ground-penetrating radar (GPR) and CCTV video pipe inspections to gather detailed information. Based on this assessment, you can then develop a detailed repair plan that addresses all identified issues and potential challenges. GPRS provides a unique suite of tools and processes that can help any professional, project manager, or company prepare for pipeline repairs. From CCTV pipeline inspection, to GPR, and even 3D Laser Scanning, GPRS offers accuracy at an unprecedented level - 99.8% accuracy for utility locating and concrete scanning alone - on more than half a million jobs, nationwide.
Key Actions:
- Perform a detailed site survey
- Utilize advanced diagnostic tools and technologies
- Develop a step-by-step repair plan
2. Use of High-Quality Materials
The materials used in pipeline repairs must meet or exceed industry standards to ensure the best results. Select materials that are appropriate for the specific conditions and requirements of the repair, such as corrosion-resistant metals, high-strength composites, and durable sealants.
Key Actions:
- Source materials from reputable suppliers
- Verify material specifications and compatibility
- Consider environmental and operational conditions
3. Skilled and Trained Workforce
Ensure that the repair team is composed of skilled and trained professionals who are knowledgeable about the latest repair techniques and safety protocols. Continuous training and certification are essential to keep the workforce updated on new technologies and industry standards. GPRS operates with an elite team of Project Managers who go through rigorous training and safety courses. Our Project Managers undergo extensive Subsurface Investigation Methodology (SIM) training, as well as OSHA 10, OSHA 30, HAZWOPER TRAINING, ERAIL SAFE, Confined Space and Fall Safety, and First Aid/CPR.
The industry standard recommends 8 hours as a minimum for training and 60 hours practicing GPR to become certified NDT Level 1 in Ground Penetrating Radar. By contrast, SIM requires 320 hours of mentorship in the field prior to 80 hours of classroom/hands-on training. Every GPRS Project Manager is SIM-certified at level 101 or higher.
In addition, the unique combination of classroom training and on-site supervised field training reinforces what a Project Manager encounters on the Job. The SIM curriculum allows them to go deeper into the technical aspects and knowledge needed to perform their jobs at the highest level.
Key Actions:
- Conduct regular training sessions
- Verify certifications and experience of personnel
- Encourage continuous learning and improvement
4. Adherence to Safety Protocols
Safety should be the top priority during any pipeline repair project. It is vital that you Implement stringent safety protocols to protect workers and the surrounding environment. This includes proper use of personal protective equipment (PPE), hazard identification, and emergency response planning. GPRS takes safety seriously. We are firm believers in continuous safety education for all our employees. Our ongoing commitment to the health and safety includes the following safety practices:
- OSHA 10-Hour Outreach - completed by every Project Manager
- OSHA 30 – completed by many of our area managers
