There was very little pre-existing data available for constructing or validating MOBEDIC. This lack became increasingly evident as the project progressed, and it was decided to gather some additional data by carrying out a mustering exercise offshore.

This exercise was carried out on Texaco's Tartan Alpha platform during February 1993. It was based on a torch fire in one of the production modules, which eventually resulted in part of the platform becoming untenable. Data on movements and response times were collected in addition to information about the routes taken. The incident was then simulated using the EGRESS model.

The results were encouraging: people did respond to alarms, and their response times did vary with their activities. Personnel reacted differently depending on their specific characteristics and on the environment and their overall behaviour was similar to what would be expected in a real situation.
