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 supports clients already in the conceptual design stage and offers 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 275 projects and installed over 20,000 km of subsea pipeline, operating a versatile fleet of specialised heavy-lift, pipelay and support vessels, designed and developed in-house. 

The latest addition to Allseas’ fleet, the 382 m long, 124 m wide dynamically positioned platform installation/decommissioning and pipelay vessel Pioneering Spirit, commenced offshore operations in August 2016. The vessel set a new offshore lifting record with her first commercial job, removal of the 13,500 t Yme production platform offshore Norway.

Lorelay  was the world’s first dynamically positioned pipelay vessel, changing the nature of the pipelay industry. 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.
