Automation XL overcomes challenges to extend life of CNR field offshore West Africa.
The mid-water arch anchorage on the FPSO had broken free and damaged the digital radio cables used for control and communications from the vessel to the unmanned, wellhead platforms. With no communication, the client had to stop production. The expense of hiring cable laying barges coupled with loss of production on such a marginal field could have signalled the end of its life.
The project presented several challenges including high humidity and high frequency of lightning strikes, movement of the vessel, bandwidth in terms of being able to provide enough data through-put for critical data components and information gathering as there was no site survey available and a lack of documentation due to the interface required with equipment from several vendors.
We delivered a digital radio solution at installation that allowed client communications to the critical control and safety systems on the unmanned installation. This comprised a 5.8Hz IP radio link between the FPSO and NUI with Cisco networking equipment to provide a pseudo multiplexor for IP traffic.
Automation XL relished coming up with a cost-effective digital radio solution to such a technically challenging project which ensured that the life of the field could be viably extended.
