Since 2019 the vessel has been off-field undergoing a life extension programme, initially at Bull Arm Fabrication Site, then Navantia, El Ferrol.

The Terra Nova field is operated by Suncor Energy Inc., with a 37.675% interest, located approximately 350 kilometres (220 mi) east off the coast of Newfoundland, Canada in the North Atlantic Ocean.

All three fields are in the Jeanne d'Arc Basin on the eastern edge of the famous Grand Banks fishing territory.

Terra Nova lost 165 m³ of oil into the ocean in 2004 because of two mechanical failures.
