The Brief Will Cover
• The Challenge of Ship Lifecycle Maintenance.
• How the Ship Maintenance Requirement is developed
• How the Ship Maintenance is tracked.
2Focused on meeting the mission.
Surface Ship Life Cycle Mandate
• To meet mission of the Navy, requires attainment of 313 ships by 2020.
• Attaining 313 requires 240 of today’s hulls to remain in service
• Maintenance strategy must be aligned in support of: – Individual ship Current Readiness – Fleet Response Plan (FRP) Ao – Expected Service Life (ESL)
Life Cycle Plan to support Current Readiness, FRP and ESL 3
NIMITZ Class

Class Maintenance Plans
• Class Maintenance Plans (CMP) are the “maintenance manual” of the ship class. Specifically included are:– Maintenance Delivery Plan including
required dry-docking intervals – Engineered maintenance
requirements such as equipment overhauls, shaft replacements, and corrosion protection
– System certification requirements (nuclear, subsafe, flight deck)
• CMPs are continuously updated based on class maintenance history
Class Maintenance Plans (CMP) = “Automobile’s Maintenance Manual”

Summary
• Ship maintenance is a complex challenge that requires overall system integration.
• Maintainability requirements developed from the system requirement and at the individual equipment level are incorporated into the CMP.
• Ship maintenance is tracked at the equipment level and lessons learned used to improve future readiness.
