TWO SHIFT WORKING AT PULROSE POWER STATION ON THE ISLE OF MAN
In common with many power stations built in the early 2000s, Pulrose CCGT plant was designed as a base load plant. Subsequently the commercial environment forced the operations team to two shift half the plant. Whilst there were a number of engineering problems that had to be addressed initially, some problems emerged after many years of operating the plant in two shifted mode. One of these problems was that the main steam stop valve and non-return steam valves were wearing and leaking allowing steam to leak into the off line boiler, causing condensation and stress corrosion cracking. This damage to the boiler resulted in a £1M repair.
