Our new deepwater construction vessel (DCV) Aegir was christened during a festive ceremony in September 2013. This latest addition to our fleet is capable of executing complex infrastructure and pipeline projects in ultra-deep water and has sufficient lifting capacity to install fixed platforms in relatively shallow water. The design is a customized Ulstein Sea of Solutions SOC 5000.

Length overall210 m689 ft
