Offshore Capabilities
The offshore pipeline installation, heavy lift and subsea construction contractor Allseas operates worldwide with a specialised fleet of heavy lift, pipelay and support vessels, designed and developed in-house. Allseas’ unique heavy lift vessel “Pioneering Spirit” removes and installs large platform topsides up to 48,000 tonnes and jackets up to 20,000 tonnes in a single lift. “Pioneering Spirit” commenced offshore operations in 2016 and set a world lifting record with the single-lift removal of Shell's 24,000 t Brent Delta in 2017. In 2013 Allseas announced plans to build a second single-lift vessel, “Amazing Grace”, for the installation and removal of the very largest existing platforms.
