Allseas installs offshore pipelines for oil- and gastransport. Allseas provides services at sea for energysuppliers. The most important services are laying pipelines and removing platforms.

In 2014 the fleat off Allseas was comprised of three ships for laying pipelines (Solitaire, Lorelay en Audacia), a support vessel (Calamity Jane) and a pontoon (Tog Mor). Tog Mor can also serve to lay pipeline, but only in shallow waters.
