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. Since becoming operational in 2016, “Pioneering Spirit” has lifted more than 130,000 t of topsides weight and installed over 2500 km of subsea pipeline. The single-lift removal of the 24,200 t Brent Delta topsides in April 2017 set a new record for a lift at sea, surpassed in spring 2019 with installation of the 26,000 t process platform for the Johan Sverdrup development offshore Norway.
