Allseas is a world-leading contractor in the offshore energy market, with dynamism, rapid progress and pioneering spirit at its core. To stay ahead of the industry, they develop tomorrow’s technology today, transforming bold ideas into state-of-the-art solutions to meet the market’s ever changing needs.

Allseas are experts in the design and implementation of large and complex offshore energy projects, with a proud history of delivering first-class services, operational excellence and dedicated expertise to clients worldwide.

Designed and optimised in-house, their versatile fleet of specialised vessels are fitted with the most advanced equipment and systems, so they can perform beyond expectation in some of the harshest and remotest environments in the world.

When it comes to speed, reliability, efficiency and capability, Allseas’ dynamically positioned pipelay vessels have shaped the offshore pipelay industry into what it is today, setting new standards for heavy, deep-water pipelines.

Their heavy lift and pipelay vessel Pioneering Spirit is a game-changer. Built to install and remove entire offshore platforms in a single lift, and lay pipelines in unlimited water depths, the world’s largest construction vessel boasts versatility and capability unrivalled anywhere in the offshore industry.

Pioneering Spirit signifies a step-change in offshore platform installation and decommissioning. Capable of lifting entire platform topsides of up to 48,000 t in a single piece, the vessel significantly reduces the amount of offshore activities, moving the work onshore where it is safer, more cost effective and carries minimal environmental risk.

Allseas supports clients already in the conceptual design stage and offer services for project management, engineering, fabrication, installation, removal and commissioning. Based in Delft, Allseas Engineering B.V. has more than 900 employees, and provides project management and engineering services to the Allseas Group.
