About
I'm a Chartered Engineer with more than fifteen years leading safety-critical energy and infrastructure delivery, from hands-on control system design through to engineering authority for £450m or more of green hydrogen capital programmes. I've directed a £320m four-project portfolio at the same time, holding one technical standard across every project rather than letting quality drift between them, and I report at Board, investor and regulator level. The foundation underneath that is unusually broad.
Six years delivering capital projects for Diageo's distilleries and maltings, end to end from malt intake to spirit tanker loading. Fiscal metering and safety systems for the UK's Oil Fuel Depots on behalf of the MoD, Thanckes, Garelochhead and Loch Striven among them. Three years inside the Ministry of Defence holding enterprise engineering authority for a major armoured vehicle programme under statutory governance.
Functional safety, IEC 61508 and 61511, and OT cybersecurity run through all of it, built into the baseline from day one rather than retrofitted once something goes wrong.
