An oil and gas company in Northern Europe recently selected the AM3440 from Loop Telecom to connect its two major ground stations with all of its exploration and production sites. iNMS software from Loop managed the network, and the Disaster Recovery feature made sure the backup site could manage the network in case of an emergency. Disaster Recovery provided geographical protection, fast synchronization, and simple switching to ensure network stability.
All of the sites in the North Sea were connected in a ring topology with the two ground stations. For more stationary production sites where tunnels and pipelines were available, fiber was used. For mobile and exploratory platforms, the nodes were connected via wireless radio links.
The AM3440 at each node concentrated and transported the following types of traffic:
• Production control via asynchronous SCADA/RTU connections on a RS232 interface
• Security management to shutdown all production in case of a leak. Also done via SCADA/RTU automation, this is a mission-critical application.
• Voice communications over FXS/FXO cards
• For a future transition to an IP network, ethernet/router and TDMoE cards
Nodes were deployed in batches, and the target size of the network was 80 nodes.
