Subsea 7 has applied to Canada’s authorities for an extension to the period one of its subsea vessels can work offshore Newfoundland due to project delays.

The Oslo-listed player is Suncor Energy’s prime offshore contractor for its US$500 million Terra Nova Asset Life Extension (ALE) scheme.

This involves upgrading the field’s floating production, storage and offloading vessel plus the subsea and mooring systems, in addition to the installation of a new subsea production system to handle output from extra wells.
