Alcatel Submarine Networks Press Release

December 14, 2017

Alcatel Submarine Networks (ASN), part of Nokia, has been awarded a turnkey contract (EPCI) by Statoil to supply and install DC/FO™ technology as the subsea control infrastructure for the Johan Castberg field in the Barents Sea.

DC/FO™ technology is an innovative and cost-effective solution developed and qualified in cooperation with Statoil. The solution bridges ASN’s highly reliable, field proven, largely deployed submarine telecom technology with Statoil’s invaluable expertise in Oil & Gas field development.

DC/FO™ technology is now available to Oil and Gas companies for the design of their subsea production infrastructure. Its selection for the Johan Castberg field confirms that such a solution meets the needs of advanced field architects, offering:

  • Standardization – the same standard cross section can be used regardless of tie back length or power consumption demand;
  • Reparability and Extendibility – The cable and its end terminations can be lifted to surface for repairs or extensions at sea with standardized jointing technology, simplifying the tie-back of new prospects and enabling phased development;
  • Open platform – electrical power and communication interfaces can be connected to any Subsea Production System (SPS) supplier equipment;
  • Virtually unlimited reach within Oil and Gas fields – the system is dimensioned to serve the longest tie backs currently contemplated by the industry;
  • Large power supply capability, compatible with ‘All-Electric' solutions.

Philippe Piron, President of Alcatel Submarine Networks said: “We are very honored of this contract award from Statoil for implementation of DC/FO™ technology on Johan Castberg, one of its most important project under development. This selection by Statoil confirms the strength of our relationship and the relevance of our solutions for future Oil & Gas subsea project development. DC/FO™ technology is a game changer that significantly cut the costs of projects, legacy subsea control system bottlenecks are removed, new applications can be connected such as AUV subsea docking for example. On longer term, All-Electric trees can be powered through DC/FO solution, allowing further cost reduction. We will continue to work closely with Statoil to leverage on submarine telecommunications technologies for new pioneering applications into the Oil & Gas fields”.


Alcatel Submarine Networks (ASN), part of Nokia, leads the industry in terms of capacity and installed base with more than 590,000 km of optical submarine cables/systems deployed worldwide. From traditional telecom to new oil and gas applications, ASN provides every part of a global undersea transmission network, all tailored to the customer’s needs. An extensive service portfolio completes its comprehensive offering for the submarine business, including project management, installation and commissioning and marine operations and maintenance performed by its fleet of cable ships.
