VIRGINIA BEACH, Va. (NNS) -- The Naval Surface Warfare Center (NSWC) Port Hueneme Division's Remote Support Coordinator presented a technical white paper, “E-Prognostics” Sept. 18 at the American Society for Naval Engineers (ASNE) Fleet Maintenance Symposium 2007.

The 11th annual symposium, sponsored by ASNE's Tidewater Section, featured senior military decision makers, equipment operators, designers, suppliers, and ship and craft repairers and maintainers of the Navy, Coast Guard, Army, and Military Sealift Command vessels.

Joel Timm spoke about the importance of e-prognostic, defined as a diagnostic and predictive analysis and its application to surface ships.

“E-prognostics is used to determine the remaining operational ability of a system, sub-system or component, and these technologies are being sought after through partnerships with industry and academia for predicting the failure of combat and weapon systems and components,” said Timm.

One of the benefits of predicting the remaining life of components, explained Timm, is that it allows for a better use of logistics, such as pre-ordering parts, and avoids complete system failure and the resulting urgency.

Other benefits to the fleet include: reduction in repair time; reduced equipment downtime; reduced manning; increased safety; increased reliability, and increased performance trending capability.

“NSWC Port Hueneme is investigating tools and methods used by the NASA Jet Propulsion Laboratory unmanned spacecraft programs,” said Timm.

E-prognostics can be applied to legacy, current and future ship systems design.

The overall goal for future combatants is to minimize manning and minimize maintenance while maximizing the operational effectiveness of the fleet systems.
