Commissioning sequencing is planned to control thermal gradients, avoid overstressing welds and ensure instrumentation is validated under operating conditions. Procedures detail purge rates, cool-down ramps, pressure equalization, leak checks and operational handover steps. During de-commissioning we emphasize safe evacuation, product recovery into ISO tanks, neutralization of residues and environmental discharge controls where applicable. Both commissioning and de-commissioning are accompanied by risk assessments, permit-to-work regimes and competent person oversight as required by PESO.
We document every step nitrogen purge logs, vent management records, final pressure tests and handover certificates to provide a clear audit trail for regulators and clients. Where tanks are relocated, we provide mechanical stabilization and transport engineering to preserve structural integrity.
