The Swiss-based Allseas Group S.A., founded in 1985 and headed by Edward Heerema, is a leader in offshore pipeline installation and subsea construction. We are experts in the execution of large and complex projects, providing worldwide support to clients from the conceptual design stage to engineering, procurement, installation and commissioning.

Allseas do not restrict ourselves to available technology; we develop new techniques and solutions wherever necessary. To date, we have executed more than 250 projects and installed approximately 20,000 km of subsea pipeline.

Allseas operate a versatile fleet of specialised pipelay and support vessels. Lorelay was the world’s first dynamically positioned pipelay vessel, changing the nature of the pipelay industry. The DP pipelay vessel Solitaire is the largest and most technically advanced pipelay vessel in the world. In 2007 Allseas’ most recent pipelay vessel, Audacia, was put into service. For shallow-water work, the pipelay barge Tog Mor complements the pipelay capability of the DP pipelayers. All four vessels operate with the automatic welding system Phoenix, developed in-house. Solitaire, Audacia, Lorelay and Tog Mor are supported by the DP trenching and subsea support vessel Calamity Jane.

The 382 m long, 124 m wide dynamically positioned platform installation/decommissioning and pipelay vessel Pioneering Spirit was delivered in 2014. The completed topsides lift and pipelay vessel will commence offshore operations in mid-2015. In 2013 Allseas announced plans to build a second single-lift vessel larger than Pioneering Spirit to be delivered in 2020. It is intended for installation and removal of the very largest existing platforms.

Allseas has offices in Châtel-Saint-Denis (Switzerland), Essen (Belgium), Delft (the Netherlands), Funchal, Madeira (Portugal), London (UK), Rio de Janeiro (Brazil), Houston (USA), Perth (Australia) and Mumbai (India).

Together with the vessels, more than 2,500 people are employed worldwide. Allseas Engineering B.V. in Delft has more than 700 employees, and provides project management and engineering services to the Allseas Group.
