Gaskets and bolting — why most flange leaks are assembly, not hardware
How a bolted joint actually seals, reading a spiral wound gasket by its colours, choosing stud and nut materials, and the bolt-up sequence that decides whether any of it works.
Risk-based inspection — deciding what to inspect, and how often
Why nobody inspects everything equally, how likelihood and consequence combine into an inspection plan, why naming the damage mechanism is the whole job, and the ways an RBI programme quietly goes wrong.
Lighting and small power — the systems people only notice when they fail
How lighting levels are set and why uniformity matters more than average lux, the three tiers of emergency lighting, and why a socket outlet in a hazardous area is not a simple thing.
Ex installation and inspection — where compliance is actually won or lost
Certified equipment is the easy part. Glands, unused entries, flame paths, IS segregation and the inspection regime are where hazardous area compliance is genuinely decided.
Inspecting and repairing structures — the other forty years
Construction is a small part of a plant's life. What degrades, why the worst mechanisms are the hidden ones, how risk-based inspection decides where to look, and why structures quietly become overloaded.
Analysers and sampling systems — where the real problem usually is
What an analyser measures that a transmitter cannot, why the sample system causes most of the failures, how transport lag limits what you can control, and why the take-off point decides everything.
Permit to work — how a plant decides a job is safe to start
What a permit actually is and what it is not, why proving an isolation matters more than making one, why confined spaces kill rescuers, and the ways a permit system quietly becomes paperwork.
