According to the company's presentation, the design for Yggdrasil combines full-field development pipelines and controls in a single integrated bundle. The bundles will be installed offshore using Subsea7’s pressurized reel-lay method, which allows the use of corrosion-resistant, mechanically lined pipe. This is also the company’s longest Swagelining polymer-lined pipe project. Seven Vega, Seven Oceans and Seven Navica will lay the pipelines.
In Brazil, stalk fabrication started for Petrobras’ Mero 4 project at the Ubu spoolbase, while the Bintan spoolbase in Indonesia completed fabrication and load-out of pipeline for Santos’ Barossa in the Timor Sea.
Offshore Guyana, Seven Borealis completed its pipelay scope for Exxon Mobil’s Gas to Energy project. The vessel installed 119 km of 12-inch carbon steel pipe, comprising 9,608 pipe joints, in S-Lay mode in water depths of up to 1,400 m, concluding the program 10 days ahead of schedule.
Seven Borealis then mobilized to Saudi Arabia for work on Aramco’s Zuluf development.
In the presalt Santos Basin offshore Brazil, Seven Vega, after completing the main pipelay scope for the Equinor-operated Bacalhau development, headed to Mero 3 in the same sector.
During the quarter, Seven Oceans finished pipelay duties for Woodside’s Scarborough (Western Australia) and its second offshore campaign for Barossa. In Norway, Seven Navica wrapped up offshore activities for the Northern Lights carbon capture project.
