Final Engineering Chosen for Alaska LNG Pipeline, Local Stakes Rise

Glenfarne, the private lead developer for Alaska LNG, announced on November 10, 2025 that it has selected engineering firm Worley to undertake final engineering for the pipeline portion of the project. The pipeline is described by the company as an approximately 807 mile route with a 42 inch diameter, intended to transport North Slope natural gas to external markets while also providing gas for in state consumption. Glenfarne took the majority developer role earlier in 2025 and frames this award as a critical step toward maintaining project momentum.

The work now under way is focused on Phase 1 of a two phase plan. Phase 1 covers the trunk pipeline and includes North Slope components for gas treatment and compression. Phase 2 would add liquefaction and export facilities and related infrastructure if sponsors move forward. Glenfarne says the near term final engineering study is intended to support a pipeline investment decision, which will be pivotal for determining the overall timeline and scale of construction activity across Alaska.

For North Slope Borough residents the implications are concrete. The project design explicitly includes facilities on the North Slope for gas treatment and compression, which creates potential for local hiring, service contracts, and support sector demand during both construction and ongoing operations. Glenfarne highlights anticipated economic benefits and job creation for Alaska communities including those on the North Slope, and the pipeline could expand the supply of natural gas available for heating, industry, and other in state uses. Additional government revenues from taxes, royalties, and local procurement would depend on final project scope and the terms negotiated with state and local authorities.

Significant steps remain before ground is broken. The near term engineering study will feed an investment decision, and project sponsors will need to secure permitting, regulatory approvals, and stakeholder agreements. Market conditions will also matter, since plans for Phase 2 depend on economics for exported liquefied natural gas. Global LNG prices and demand, capital costs, and financing terms will all influence whether and when the export portion advances.

Selecting Worley reflects a preference for an experienced firm with Alaskan project history, according to Glenfarne. If the study supports a positive investment decision, the pipeline selection could mark the most tangible movement in years toward channeling North Slope gas to markets while creating locally anchored infrastructure and jobs.
