As a fast-moving heavy lift vessel, Aegir offers unique offshore transport, installation, and removal solutions. Aegir is one of the world's largest monohull crane vessel and has a proven track record across a wide range of offshore projects. Optimized for fast transit speed, Aegir can mobilize worldwide and work in any water depth.
Due to Aegir's retractable thrusters, shallow draft, and extensive clear deck space, the vessel has the possibility to load-out directly from the quayside and transport on deck, reducing both yard and transport costs. While on location, Aegir's DP3 dynamic positioning system provides accurate and stable positioning. The vessel has a lifting capacity of 5.000 metric tons, and the option to use a split main crane block offers flexibility by allowing the upending of tall structures and long piles, similar to Heerema's dual crane vessels.

Length overall210 m689 ft
