Major oil company TotalEnergies has upgraded its operational technology (OT) network with infrastructure from connectivity services and intelligent networking tools provider Allied Telesis, as part of its plan to ensure legacy OT in its North Sea oil platforms is replaced by efficient critical infrastructure.
The new network comprises multiple dual redundant networks, interconnected among three oil and gas platforms. They serve over 400 nodes and the platforms’ distributed control system, emergency shutdown safety instrumented system, fire and gas safety instrumented system, electrical control system, multi-phase pump control system, and alarm management systems.
