Frame 9E Maintenance Considerations

Key Maintenance Recommendations

Boroscope / Inspection: Annual / 8000 hrs.

Hot Gas Path Inspections: Start of Contract and

Every 24,000 hrs.

Major Overhauls: Start of Contract and

Every 48,000 hrs.

Warranty: Available with WG

LTSA / O&M

Outage Planning: Developed through

integrated LTSA /

O&M Contract

Parts / Inventory: Analysis performed

and

recommendations

made by WG to

achieve maximum

availability at lowest

Long Term Service Agreements (LTSA)

Key Features

• Levelized Maintenance Fees = Predictable Costs

-Fired hour / monthly fees

-No “spike” in fees during major maintenance

-Simplified maintenance budgeting

• Outage Flexibility = More Revenue

-Routine maintenance by contracted service partner (WG)

-Ongoing record keeping and monitoring

-Extended maintenance intervals based on condition

-Parts and repair options

• Outage Planning = Lower Owner’s Risk

-Scheduled and unscheduled maintenance included

-Maintenance planning, parts sourcing by WG

-Maintenance planned around scheduled plant outages

Operations and Maintenance (O&M)

Key Features
