What does the rig look like today, compared with the model?
- Data
- A large archive of oil rig photographs that had never been analysed, plus the digital models of the structure.
- Built
- A comparison of the actual condition in the images against the digital models, flagging ongoing change such as rust and unexpected issues such as missing extinguishers.
- Result
- Missing features in the real environment mapped, and misplaced items highlighted.
The question
The operator held a large set of rig images that nobody had used beyond the inspection they were taken for. The question was whether that archive could say anything about how the structure was changing between visits.
What we did
We analysed the images against the digital models of the rig, so each change could be located on the structure rather than described in a report. The analysis picked up the expected wear, such as rust, and also issues nobody had been looking for, such as extinguishers missing from their positions.
What it changed
The results made a case for keeping an as-built model up to date, so safety and operational changes can be tracked against it over time.
