I work in the control and automation discipline. There are basically three systems on the oil and gas platforms that I concentrate on. The first detects fire or gas escapes and has closed circuit cameras - that kind of thing. Next are mechanisms that trip safety interventions at the first sign of an unexpected rise in temperature. And then there are conventional meters and gauges that monitor flow rate, temperature and pressure. In the old days, Instrument Engineers walked around the platform with clipboards, checking the gauges one by one. Technology has now moved on. We now have sensor technology and a control centre located onshore at Bintulu, Sarawak, with a big computer at the heart of things. In the design of a new platform, I am involved from the start - in the same way that we do early environmental impact and qualitative risk assessments. I also get involved in the upgrade the systems of existing platforms. Right now I'm doing both tasks because I have to tie in the control systems of a new satellite platform around an older hub.
