A NEW PARADIGM FOR SUBSEA CONTROL POWER AND COMMUNCIATION DISTRIBUTION
ASN’s DC/FO solution is a new generation subsea infrastructure delivering power and Fibre Optic (FO) communication from onshore or offshore host facilities to subsea production systems.
The trend toward increased monitoring and all-electric subsea production architectures calls for increased demand in subsea control power and communication. The technology offered by ASN allows the removal of known bottlenecks from legacy subsea control infrastructures.
The ASN DC/FO technology allows the supply to multiple subsea connection points of significant power and communication capability in a highly reliably and cost effectively manner, to multiple locations within a diverse and/or widespread O&G; field(s).
The subsea interface points of ASN’s DC/FO solution are standardized and compatible for interfacing with any subsea production system.

VALUE EXPECTED FOR AN ASN'S DC/FO INFRASTRUCTURE
- Very long step out to host facility
- Constant power supply level & capacity at subsea connection points, independently from distance to host facility and from user’s power demand
- No intermediate subsea connection points
- Independency with SPS (clear-cut interfaces)
- Flexibility and scalability: A DC/FO infrastructure can be repaired in case of external aggression and can be expanded over time to connect new planned or unplanned production sites
- High availability (reliability grade inherited from submarine telecommunication technologies, self-healing capability and redundancy)
