The Swiss-based Allseas Group S.A., founded in 1985 and headed by Edward Heerema, is a world- leading contractor in offshore pipeline installation, heavy lift and subsea construction. Experts in the execution of large and complex projects, Allseas support clients already in the conceptual design stage and offer services for project management, engineering, fabrication, installation and commissioning.

For over 30 years, Allseas has been developing cutting-edge technology and pushing the boundaries to deliver state-of-the-art solutions to meet the market’s ever-changing needs. Worldwide Allseas has executed more than 290 projects and installed over 21,000 km of subsea pipeline, operating a versatile fleet of specialised heavy-lift, pipelay and support vessels, designed and developed in-house.

Allseas’ record-breaking platform installation/decommissioning and pipelay vessel Pioneering Spirit commenced offshore operations in August 2016 with the safe and successful removal of the 13,500-t Yme platform offshore Norway. In April 2017 the vessel set a new offshore lifting record with the single-lift removal of the 24,000 t Brent Delta topsides from the North Sea.

As the world’s first pipelay vessel to operate on full dynamic positioning, Lorelay  introduced a new generation of offshore pipelaying. Solitaire has set new standards in the pipelay industry. She has achieved lay speeds of over 9 km a day, and holds almost every record for heavy deep-water pipelines.

Allseas employs approximately 3000 people and holds permanent offices in Switzerland (the corporate head office), Belgium, Brazil, the Netherlands, USA, Australia, Portugal and UK. Allseas Engineering B.V. in Delft has more than 800 employees, and provides project management and engineering services to the Allseas Group.
