Commissioning, FAT & SAT

We develop FAT and SAT plans that define objective test steps, pass criteria, evidence capture and defect management processes. FAT usually covers I/O simulation, sequence verification, alarm checks, fail-safe behaviour and operator workflows before equipment leaves the workshop. SAT confirms installed performance, field wiring integrity, process interactions and operational readiness on site. We use structured punch lists with ownership and due dates so issues are visible and closed in a controlled way. This approach helps stakeholders make informed go-live decisions rather than relying on assumptions. It is particularly useful on multi-contractor projects where responsibilities can become unclear under schedule pressure. With disciplined testing documentation, clients gain confidence that system behaviour matches design intent and that unresolved risk is understood before production starts.

Successful commissioning needs technical leadership and disciplined coordination. Our engineers manage workfront planning, permit interfaces, shift handovers, daily issue review and stakeholder communication through to stable operation. We track key readiness metrics such as open defects, test completion, training status and spare part availability so decisions are based on current facts. For upgrades, we prepare cutover windows, rollback plans and post-start support rosters to protect uptime. For greenfield projects, we sequence subsystem energisation and integrated trials to reduce conflict between disciplines. Handover includes as-built records, backup sets, outstanding actions and support contacts. This service gives project teams a clear path from mechanical completion to reliable production, with fewer surprises and better accountability across all involved parties.
