I close the gap between what engineering assumed and what the field actually looks like. 4 years on marine and offshore projects across Malaysia, Indonesia, and France - in shipyards, on barges, on-site. Not in an office. I've seen what happens when that gap isn't managed early enough: delays, rework, and structural issues that should have been caught two months prior. My work sits at the intersection of Installation Readiness, Yard Supervision, and Client Representation. I make sure complex assets get built to spec, mobilized on time, and that the client isn't blindsided by what shows up offshore. **What that's looked like in practice:** → Managed Installation Readiness for a $25M GRP nearshore structure in Malaysia - offshore spread of 4 barges, 5 tugs, 5 multi-disciplinary vendor streams. Technical readiness and just-in-time availability across the board. → Identified structural cracks from a design/field tolerance mismatch (±3mm) before installation. Escalated to engineering, led field implementation of the revised solution. Avoided structural failure and schedule impact. → Rebuilt a failing recirculation system on a naval damage control simulator (gravity-based → pump-based) under operational constraints. Managed SAT, delivered, trained naval personnel. I work through Thalen Maritime, my independent consultancy based in Bangkok (HK entity). Available for field-based and remote missions. ASEAN priority, international mobility.
