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 themselves to available technologies but develop new techniques and solutions wherever necessary. To date, we have executed more than 200 projects and installed over 16,350 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.

In June 2010 Allseas awarded the contract for building its 382 m long, 117 m wide dynamically positioned (DP) platform installation / decommissioning and pipelay vessel Pieter Schelte  to the Korean shipyard Daewoo. Delivery of the completed single-lift and pipelay vessel is expected at the end of 2013, ready for offshore operations in early 2014.

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

Together with the vessels, more than 2000 people are employed worldwide. Allseas Engineering B.V. in Delft has approximately 600 employees, and provides project management and engineering services to the Allseas Group.
