Colin Weil has been involved in heat transfer since the early 1970's working for design houses such as Powergas (aka Davy), Badger and then Marathon Oil. He started out as a vessel engineer before getting involved in the thermal and mechanical design of (unfired) heat transfer equipment, progressing to what is euphemistically called a generalist. He became an independent consultant in 1996 and after a few years trouble shooting of broken or misbehaving heat exchangers become a programme manager for various research projects covering such diverse topics as multiphase flow, severe fires, 2-phase pressure relief sizing and tube failure in high pressure heat exchangers. In the background he was sucked into the world of drafting industry standards. He has worked for such organisations as the Energy Institute, Imperial College, and API. In recent years he has reduced his workload but is still directly involved in the drafting of API and ISO standards. He is chair of the BSI shadow sub-committee with responsibility for the ISO sub-committee that covers oil and gas equipment such as heat transfer, rotating equipment, piping, HVAC, pressure relief and topside safety systems.

In Colin's spare time he has been the Honorary Secretary for the Heat Transfer Society for more years than he should and has looked after the nuts and bolts for the annual dinner since there were trolley buses in London.
