1. Purpose. To establish policy for the Surface Ship
Engineered Operating Cycle Program.
2. Scope. The Surface Ship Engineered Operating Cycle Program
applies to all Navy battle force surface ships and patrol craft
(PC) under cognizance of Director, Expeditionary Warfare (OPNAV
N95) and Director, Surface Warfare (OPNAV N96). It does not
apply to Military Sealift Command ships, leased vessels, boats
and craft other than PCs.
3. Background. The Surface Ship Engineered Operating Cycle
Program addresses the identification, documentation, tracking,
and execution of the minimum assessment and maintenance tasks
necessary for a ship to achieve expected service life (ESL),
including actions required when exceeding established
periodicities for these tasks. The class maintenance plan
identifies all maintenance tasks, with periodicities, for a
given class. Class maintenance plan tasks determined necessary
for compliance with this instruction are identified as Surface
Ship Engineered Operating Cycle tasks. The engineered operating
cycle is the disciplined assignment of class maintenance plan
tasks throughout a ship’s life cycle.
4. Discussion
a. An engineered timely approach to adequately accomplish
the minimum maintenance tasks necessary for achieving a ship’s
ESL will reduce costs to execute those tasks in future years;
minimize excessive and unplanned costs to correct any resulting
deficiencies; and provide pressure on modernization and new
construction budgets to rectify these maintenance shortfalls.
