Engineering change approval workflow

This engineering change approval workflow gives plant teams a visible route from a change request through impact assessment, safety review, operating approval, implementation, and closeout. It distinguishes work that has a safety impact from routine changes and also separates outage work from changes that can be completed while equipment remains available.

Preguntas frecuentes

Preguntas habituales

What is an engineering change package?

It normally includes the proposed design, impact assessment, drawings, and implementation plan.
