Similar to the gas turbine, the generator set, heat recovery steam generator, steam turbine generator, fuel compressor and black start diesel all require only very light preventive maintenance. To per- form the infrequent corrective actions, ship technical staff needs only minimal training. The table on the previous page illustrates the requirements and frequen- cy for the on-ship maintenance routine of the COGES system.
To meet the needs of customers across the globe, GE maintains a robust inven- tory of spare engines and parts. An exten- sive network of GE authorized service providers ensures world-class support of
GE engines for decades to come. When overhaul is required — on average, af- ter 50,000 operating hours — rather than service in place as is the norm for diesels, the gas turbine is removed to a land-based facility for overhaul. The re- moved asset is replaced with a spare en- gine, all within 24 hours, so that the ship is quickly returned to revenue service.
The installed gas turbine is immediately ready for unrestricted service since no break-in period is required. Gas turbine removal is easily timed to coincide with scheduled ship maintenance. Thus GE’s maintenance philosophy, combined with high reliability and a compact, easy-to- remove design, yields increased ship availability.

The two dual-fuel powered LM2500 gas turbines (LNG and liquid) propel the world’s fastest commercial ship to more than 50 knots. A CSA tailored expressly for Francisco includes both scheduled
