4 November 2025 — Allseas has secured a contract to install a new 150-kilometre, 24-inch export pipeline in the central Gulf of Mexico, increasing oil transport capacity, flexibility, and efficiency across the region.

The Rome Pipeline Project was awarded by Shell Pipeline Company LP, acting on behalf of Amberjack Pipeline Company LLC, a joint venture between Shell Pipeline Company LP and Chevron Pipe Line Company. The line will connect Shell’s Green Canyon 19 (GC-19) platform to the Louisiana coast, strengthening Shell’s existing Gulf of Mexico pipeline network.

Allseas’ responsibilities include the engineering, procurement, and installation of the new pipeline. The anchor barge Sandpiper will complete the nearshore section in 2027, while the dynamically positioned pipelay vessel Solitaire will handle the deepwater section in 2028.

The Rome Pipeline forms part of a broader strategy to expand and modernize Gulf of Mexico export infrastructure, following earlier projects such as the Amberjack Debottleneck Project, completed by Allseas in 2016. To date, the company has installed approximately 8,000 kilometres of subsea pipelines in the region.
