1. Condition & Performance Monitoring Department

• Responsible for decreasing exploitation costs & increasing operational profit

• 18 People (militair, change every 2 – 3 years)

• Based in Den Helder

Ministerie van Defensie5

2. Maintenance concept (throughout the years)

Maintenance concepts:

• Corrective maintenance - run to failure

• Preventive maintenance - running hours - calender data - OEM advise

• Condition Based Maintenance (CBM)
