Calls and Field Visits - Engines• Operations can be automated but still requiresignificant operator attention• Siloxane cleaning dropped maintenance costs• Preventative maintenance is labor intensiveand could be done in house or contracted out• “Top Ends” and Major Overhauls every 3-5years– Contracted out– Takes ~1 month• Availability can be good but is highly dependenton proper maintenance by owner
Calls and Field Visits – Steam Turbine• Operation is automated and requires lessoperator attention• Responds well to changing loads• Preventative maintenance is done in house andconsists of minor procedures and monitoring• Major Rotor Overhauls every 5-7 years– Contracted out– Takes ~1 month• Availability is very high and major O&M issues are rare• SWRP boiler feed water system needs upgrading
