CONCEPT DEVELOPMENT / FEL | UPSTREAM OIL & GAS

Engineering decisions
before FEED.

Study Manager and Senior Concept Engineer focused on FEL1-FEL2, Pre-FEED, brownfield development and multidisciplinary integration - turning complex project constraints into decision-ready concepts.

Project value is often determined long before detailed engineering starts. The critical work is making assumptions visible, integrating disciplines, testing options and creating a decision that can survive the transition into execution.
