Telic Engineering Ltd received an assignment to represent MTU Power as their control and instrumentation engineer to support the start-up of a GE LM5000 gasturbine-compressor following a 4000 hour preventative maintenance service on board the ConocoPhillips Britannia platform located offshore, UK.
The tasks consisted of monitoring the control system for proper sequencing, checks for alarms and indications and ensuring that any occurring alarms are explainable or perform troubleshooting when issues occur. In addition control application changes were requested, implemented and tested to improve the start-up and enhance the protection with regards to vibration monitoring.
The LM5000 is used primarily for co-generation, power generation and mechanical drive applications. It derives from the CF6-50 aircraft engine and is a two-shaft engine with an aerodynamically coupled power turbine.
