Allseas is a world leader in offshore pipeline installation, heavy lift and subsea construction. Our approach is to support clients already in the conceptual design stage, and offer services for project management, engineering, fabrication, installation and commissioning.


We excel in the design and execution of large and complex offshore projects, and operate worldwide with a versatile fleet of specialised heavy lift, pipelay and subsea installation vessels designed and developed in-house. We have executed more than 275 projects and installed more than 20,000 km of pipeline.


The latest addition to our fleet, the 382 m long, 124 m wide heavy lift and pipelay vessel “Pioneering Spirit” removes and installs large oil and gas platform topsides up to 48,000 t and jackets up to 25,000 t in a single lift. In August 2016 the vessel removed the 13,500 t Yme platform, followed by the removal of the 24,000 t Shell Brent Delta platform in April 2017. With this project a new record for an offshore lift was set.


Dynamism, inventiveness, rapid progress and a no-nonsense attitude are the hallmark of Allseas. For over 30 years we have been developing cutting-edge technology and pushing the boundaries to deliver state-of-the-art solutions to meet the market’s ever-changing needs.
