Optimal undertook a Failure Mode driven maintenance and spares strategy review for the main power generation gas turbines on two offshore platforms with the aim to increase availability of the turbines from 92% to 98%. Although there was redundant generative capacity there was still a high potential for power interruption during load shedding and run ups on switch over which caused production problems.
In total, there were 5 turbines (3 x PGT25 and 2 x LM2500 Dual Fuel Aeroderivative turbines) with differing age and manufacturing origins, and as a result maintenance and spares had to be developed for each turbine system. For this scope, Optimal carried out a holistic Reliability Centred Maintenance (RCM) derivation study (including vendor support tasks) for the whole of the power generation systems including:
