15+ Years Exp.

With a comprehensive career bridging major oil & gas operators, tier-one EPCIC contractors, and specialized engineering consultancies in Vietnam, Singapore, and Malaysia, I specialize in navigating process designs from feasibility conceptual study through offshore commissioning.

My engineering expertise centers on FPSO topsides separation trains, high-ratio multi-stage centrifugal gas compression, vapor recovery units (VRU), sour gas treating (amine/membrane), dehydration (TEG/mol-sieve), and gas-gas eductors for low-pressure flare recovery.
