Automated Verification of Blowdown events on Edvard Grieg

A plant blowdown is a safety critical operation that makes sure the facility pressures are reduced to safe levels in an emergency or when the plant is shut down*. Blowdowns are fast events that rely on a hundred or more valves opening and closing at the right time. A facility is divided into different “blowdown segments” and checking that everything worked correctly for each of these segments can take an engineer a week or more. Yet most of this time is spent gathering the right information and visualising it for each segment. Using a Knowledge Graph combined with Event Detection and a simple Python script, all part of the Eigen Analytics Platform, Eigen were able to automate this process to let Lundin’s engineers spend more time on adding value.
