What an Owner’s Engineer Does on U.S. LNG Projects

An Owner’s Engineer plays a vital role in the successful delivery of LNG projects in the United States, acting as the independent technical representative of the project owner throughout the full project lifecycle. Their primary focus is ensuring that the facility is delivered safely, complies with all regulatory requirements, and performs reliably over its operational life.

Owner’s Engineer vs. EPC Contractor: Who Do They Actually Represent?

Unlike EPC contractors or equipment vendors, the Owner’s Engineer represents the long-term interests of the owner. This includes prioritizing safety, operability, lifecycle performance, and regulatory compliance over construction speed or vendor-specific execution approaches.

Core Responsibilities: Design Review, Marine Interfaces, and Construction Oversight

On U.S. LNG projects, Owner’s Engineer responsibilities typically include independent design and engineering reviews, verification of compliance with statutory and classification requirements (including international maritime regulations and IACS standards such as ABS and Lloyd’s Register), and management of interfaces between process facilities and marine LNG systems. Additional responsibilities include construction and shipyard oversight, as well as support during commissioning, startup, and operational readiness phases.

FERC Compliance and Regulatory Alignment on LNG Export and Liquefaction Projects

For LNG export terminals and liquefaction facilities operating under regulatory frameworks such as the Federal Energy Regulatory Commission, the Owner’s Engineer also helps ensure engineering execution aligns with approved project commitments and regulatory conditions established during the permitting process.

Reducing Risk and Controlling Lifecycle Costs Through Independent Technical Oversight

Independent technical oversight ultimately helps project owners reduce risk, control lifecycle costs, and ensure LNG facilities are delivered safely, efficiently, and in line with long-term operational expectations.
