Allseas Complete Installation of Pipeline for N05-A Gas in Dutch North Sea

Allseas has announced today their successful completion of the pipeline installation and post-lay activities for the N05-A natural gas development, a flagship project in the Dutch North Sea led by Dutch energy operator ONE-Dyas.

The N05-A development, located about 20km north of the islands Schiermonnikoog and Borkum, represents the largest Dutch investment in natural gas in over 15 years and aims to deliver a reliable, cleaner energy supply for Dutch and German households and businesses.

ONE-Dyas entrusted Allseas’ offshore engineering expertise with the installation scope for N05-A’s critical pipeline infrastructure. Their scope included the transport and installation of a 15km natural gas export pipeline that links the innovative, wind-powered platform to the existing NGT pipeline which runs to Uithuizen.

Their vessel Lorelay  executed the shallow water pipelay operations, pipeline burial and pre-commissioning activities, ensuring a seamless project progression.

“With the swift and safe installation of this pipeline, we’re not only helping ONE-Dyas meet their ambitious first-gas timeline, but we’re also supporting an ambitious energy project that’s crucial for the Netherlands,” says Project Manager, Paul van Haestregt.

“This pipeline will deliver reliable and affordable gas to Dutch homes and businesses while also supporting the country’s transition to cleaner energy sources.”

The N05-A project is an innovation in clean gas production. The production hub is powered by offshore wind, making it the most environmentally friendly natural gas development in the North Sea.

The infrastructure is designed to support future development of green hydrogen and carbon capture and storage (CCS) – emerging sectors in which Allseas’ pipeline design and installation expertise is poised to play an important role.

With 40 years of pipeline installation experience, and over 7000km of pipeline in the North Sea alone, Allseas track record in the safe and reliable installation of natural gas pipelines is unmatched.

Their contribution to the N05-A project exemplifies their commitment to leveraging offshore expertise for innovative and sustainable energy solutions.
