SYNTHETIC DEMO — Alder Bank Alpha is a fictional offshore installation and every record here is invented for an AI benchmark. This is a decision aid, not approved operational software: it cannot approve continued operation, deviations, permits (PTW), isolations, fitness-for-service or a schedule, and it makes no predictive-maintenance claim. Approvals rest with authorised humans under the live systems described in the synthetic basis (OIM, Technical Authorities, Production Coordinator). PTW and isolations are authorised at the worksite only.
