Life Cycle Approach to Maintenance Engineering & Planning

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

Date Deployed: May 3, 1975 Unit Cost: About $4.5 billion Propulsion: Two nuclear reactors, four shafts. Length: 1,092 feet Displacement: 97,000 tons Speed: 30+ knots Crew: Ship's Company: 3,200 -Air Wing: 2,480. Armament: Multiple NATO Sea Sparrow, Phalanx CIWS, and (RAM) mounts. Aircraft: 60+

4Plan is to maintain the USS NIMITZ for 50 years.

The Challenge: Complexity

NIMITZ Class will support several new variations of aircraft over the 50 years of service.

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.
