Oil and Gas Pipeline and Related Structures Construction
NAICS 237120 · United States · 2022 edition
This industry comprises establishments primarily engaged in the construction of oil and gas lines, mains, refineries, and storage tanks. The work performed may include new work, reconstruction, rehabilitation, and repairs. Specialty trade contractors are included in this industry if they are engaged in activities primarily related to oil and gas pipeline and related structures construction. All structures (including buildings) that are integral parts of oil and gas networks (e.g., storage tanks, pumping stations, and refineries) are included in this industry.

For Oil and Gas Pipeline and Related Structures Construction, clarify the services, contracts and consequences of an error. Review pollution liability, completed operations, workers' compensation. Confirm which professional activities and additional services the proposed coverage actually addresses.
Questions to ask
- What types of pipeline work does the contractor primarily perform — gathering, distribution, or large-diameter transmission — and does the scope include refineries, processing plants, or storage tank farms?
- Does the contractor take on any design-build, EPC, or construction management roles, or is work strictly as a general or specialty subcontractor?
- Is contractors pollution liability currently carried, and what are the current limits and retroactive date?
- What percentage of revenue comes from projects where the contractor is enrolled in an owner- or contractor-controlled wrap (OCIP/CCIP) program?
- Are there any prior pollution incidents, environmental notices of violation, or open remediation obligations?
- Does the contractor perform any work in, over, or under navigable waters or offshore environments?
- What is the approximate value of the owned equipment fleet, and is it deployed to remote project sites requiring transit coverage?
- What is the workers' compensation loss history over the past five years, and are there any open or reserved claims?

Establishments in this class construct, reconstruct, rehabilitate, and repair oil and gas pipelines, gathering systems, transmission mains, pumping and compressor stations, refineries, petrochemical plants, natural gas processing facilities, and associated storage tanks. Work typically involves trenching, pipe installation and welding, hydrostatic testing, tie-ins to existing systems, and site civil work. Crews typically operate in remote, rural, or industrial corridor environments and often work under owner-controlled insurance programs (OCIPs) or contractor-controlled programs (CCIPs) on larger projects.
