Subsea7 has issued updates on its offshore oil and gas and wind projects in its latest results statement.
In the Norwegian North Sea, the company completed rigid pipelay fabrication for Aker BP’s Yggdrasil project at its Vigra spoolbase, while construction of the pipeline bundles continued at the Wick spoolbase in northern Scotland.
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.
In the offshore wind sector, the installation vessels Seaway Strashnov and Seaway Alfa Lift have been busy at Dogger Bank B, and Seaway Aimery at Moray West, which are both in the UK North Sea.
Seaway Ventus completed its initial 11 turbine installation scope for Gode Wind 3 in Germany and then turned to Borkum Riffgrund 3, where it has installed 11 turbines to date. The vessel will be fitted with a gripper for the 2024-25 winter season, ahead of installing 85 foundations at East Anglia 3 in the southern North Sea in 2025.
Finally, Seaway Phoenix continued activities in Taiwan for the Zhong Neng and Yunlin offshore wind parks, while Seaway Moxie also sailed to Taiwan to support work on the Yunlin wind farm.
