KCA Deutag was awarded the Hebron Platform drilling operations and maintenance services contract.
It will start with an estimated three-year pre-operations phase, followed by a nine-year operations and maintenance program with an option to extend.
KCA Deutag's expansion into eastern Canada capitalises on the work by its rig engineering design division RDS.
RDS has been carrying out the front-end engineering and detailed design of the Hebron rig facilities since 2010.
