What does a pipeline need before it can return to service or carry a new product? The answer depends on what’s in the line now and what must happen next. NiGen supports pipeline maintenance and new construction with on-site nitrogen, compressed air, and field equipment. Our team works with operators to plan the gas supply and equipment needed for onshore and offshore projects.
As a pipeline maintenance company, NiGen supports:
- Pigging and purging: Dry air or nitrogen to propel cleaning, displacement, and inspection pigs and to purge pipeline segments.
- Commissioning and decommissioning: Planning and field support when bringing a line into service or taking it out of service.
- Inerting and drying: Nitrogen supply and drying equipment selected for the line and its required conditions.
- Pressure testing and leak detection: Support for pneumatic testing and related procedures.
On-Site Nitrogen for Pipeline Services
Nitrogen purity depends on the product in the line and the job being performed. For pipeline displacement, the required purity may range from 92% to nearly 100%. Ethylene and butadiene pipelines may require 99%–99.9% purity, while crude oil applications may use 94%–98%.
NiGen’s containerized membrane nitrogen systems can provide gas at the job site, including remote onshore and offshore locations where liquid nitrogen delivery may be difficult. The team can help determine the nitrogen supply and supporting equipment needed for the project.
Equipment Rentals for Pipeline Services
NiGen provides rental equipment to support pipeline pigging, purging, drying, and related work. Depending on the project, available equipment includes:
- Portable diesel air compressors
- Desiccant air dryers
- Booster compressors
- Atmospheric vent silencers
- Air coolers and portable fuel tanks
- Nitrogen generator rentals
Pipeline Project Experience
NiGen has supported onshore and offshore pipeline projects for both existing systems and new construction. Past projects have ranged from 1 to 1,100 miles, with pipeline diameters from 2 to 42 inches. Our team works with pipeline companies on commissioning and decommissioning procedures, including projects that require dewatering and drying before the line goes into service.
For urgent or changing project schedules, NiGen can help identify the on-site nitrogen, compressed air, and rental equipment needed for the next stage of work.
Discuss Your Pipeline Project With NiGen
The right equipment and gas supply depend on the line and what needs to happen next. When you contact NiGen, it helps to have these details ready:
- Work required: Does the line need pigging, purging, product displacement, testing, or drying?
- Pipeline details: What are its diameter, length, access points, and connection requirements?
- Next steps: What condition must the line meet before it returns to service or carries a new product?
NiGen can review the project requirements and recommend the on-site nitrogen, compressed air, and rental equipment needed for the work. Contact NiGen International to discuss your pipeline project.
