Brownfield expansion of an existing refinery, adding a new crude distillation unit and associated utilities. Full HAZOP compliance and ATEX-rated electrical installation.
Working inside a live refinery with continuous hydrocarbon processing meant all hot-work and electrical isolation had to comply with a daily PTW (Permit to Work) regime, with simultaneous operations requiring deep contractor coordination.
We established a dedicated simultaneous operations (SIMOPS) team, implemented an electronic PTW system integrated with the refinery's DCS, and pre-fabricated 80% of the CDU structural steel off-site to minimise live-area exposure.
Crude distillation unit commissioned on time with zero hydrocarbon releases during construction. ATEX electrical installation passed third-party Area Classification Verification. Refinery throughput increased by 28%.
