Offshore pipeline installation, heavy lift and subsea construction contractor Allseas operates worldwide with a versatile fleet of specialised heavy lift, pipelay and support vessels, designed and developed in-house.
Allseas’ record-breaking heavy lift and pipelay vessel “Pioneering Spirit” set a new record for an offshore lift in April 2017, with the successful removal of Shell’s iconic 24,000-t Brent Delta topsides.
“Pioneering Spirit” is a game-changer, boasting lifting and pipelaying capabilities unrivalled anywhere in the offshore industry. Built to install and remove large oil and gas platforms in a single piece, she is capable of lifting platform topsides up to 48,000 t, platform jackets up to 20,000 t and laying record-weight pipelines at all water depths.
