The framework agreement has been signed for an initial five-year period, with five optional one-year extensions. It is expected to be worth between GBP20 and 30 million over the first five years. The contract encapsulates the two companies’ working relationship, which has been functional since the 1970s.

The deal reportedly brings Aker Kvaerner Subsea’s controls delivery and service, including aftermarket services, into a one-contract arrangement to ensure maximum efficiency in supporting Shell’s projects.

Delivery of the terms of the agreement will be managed from Aker Kvaerner Subsea’s Aberdeen operations, where the global management of the controls systems organization is located.

Remi Birkeland, senior vice president for controls, Aker Kvaerner Subsea, said: The agreement means Shell will get a sustained, across-the-board service to meet its current operational requirements. Delivering such a broad scope of services needs a single focal point and this agreement avoids the inefficiencies of one-off contracting.
