Shell secures pipelayers for US Gulf trunk oil export line 

Allseas has won a contract from Shell to install a trunk pipeline for a Green Canyon platform to the Louisiana coast to increase output capacity from the oil major’s production facility.

Two of its vessels will install a 150-km, 24-inch Rome pipeline from Shell’s Green Canyon 19 platform on behalf of Amberjack Pipeline Co, a joint venture between Shell Pipeline and Chevron Pipe Line. The line will add vital capacity to Shell’s extensive Gulf of America pipeline network, significantly enhancing oil transport capacity, flexibility and efficiency.

Allseas will use its automatically positioned anchor barge Sandpiper to execute the nearshore section in 2027, followed by dynamically positioned pipelay vessel Solitaire to install the deepwater section of this pipeline in 2028.

The Rome Pipeline is part of Shell and Chevron’s broader strategy to expand and modernise their Gulf of America export infrastructure and builds on previously executed projects by Allseas, such as the Amberjack Debottleneck Project completed in 2016.

To date, Allseas has safely installed around 8,000 km of pipelines in the US Gulf, creating subsea arteries that keep oil and gas flowing from deepwater fields to shore terminals.
