Outline • Navy Environmental Systems Acquisition
Strategy• Commercial Standards in Navy Designs
– Benefits– Risks
• Where are the gaps?

Navy Environmental Systems Acquisition • Historical Approach
– Specific Navy designs were required to meet unique space and weight limitations, as well as safety, shock, and vibration requirements
– Military specifications and standards– Custom Navy designs

Navy Environmental Systems Acquisition • Historical Approach
– Small market drove higher costsSpecific materials for Navy useShock, vibration and EMI qualificationsSpace, weight, safety requirements
![Page 5: Importance of Commercial Standards in Navy Environmental System Acquisition](https://reader036.vdocument.in/reader036/viewer/2022062501/56816847550346895dde2bc3/html5/thumbnails/5.jpg)
Navy Environmental Systems Acquisition • Acquisition Reform
– Open competition– Performance-based specifications– Problem: Design yards often make hardware selections
with acquisition cost as principal driverLittle regard for Total Ownership Costs
– Range of commercial systems and components across ship classesOWS, OCMMarine Sanitation Devices (MSD)Pumps, valves
– Logistics, training, maintenance burdens and escalating costs associated with multiple designs

Navy Environmental Systems Acquisition • Desire for Commonality
– “Pendulum must swing back” to reasonable, middle ground
– First step: develop strong set of commercial standards including performance, maintainability and reliability, as well as Navy unique requirements
– Invoke commercial standards in new ship specifications
– Commercial industry responds with products ready for Navy applicationMust have competitive market from which to choose

Navy Environmental Systems Acquisition • Desire for Commonality
– Navy uses Technology Identification and Assessment Process (TIAP) to evaluate alternatives and choose best option for new ships
Primary goal is to have specifications and standards in place that meet long term Navy needs

Benefits of Common Systems
• Reduce number of system designs in fleet, simplifying– logistics– training– operations– maintenance
• Reduce total ownership costs
![Page 9: Importance of Commercial Standards in Navy Environmental System Acquisition](https://reader036.vdocument.in/reader036/viewer/2022062501/56816847550346895dde2bc3/html5/thumbnails/9.jpg)
Benefits – Solid Waste Pulper Example
• National Defense Authorization Act for FY1997 required processing of paper, cardboard and food waste from ships beyond 3 nm– Large and/or Small Navy Pulpers installed on
every ship by Dec 2000• Produces non-floating seawater slurry that
can be discharged overboard• Easy to use, rugged, made with CRES
materials• Common logistics, training, O&M
throughout fleet reduces costs to Navy

Risks
• Navy’s unique mission makes many commercial standards insufficient by themselves– limited space for equipment footprint,
operational and maintenance envelopes– weight, center-of-gravity (CG) restrictions– shock, vibration, noise, EMI– unpredictable operating profile– varied skill level of average operator

Risks
• Intense pressure from ship design offices to not deviate from baseline design– control acquisition costs– expired military specs and standards have
been selected over active commercial standards in some new designs

Where are the gaps?
• Oil pollution abatement– F 2283-04: incorporate comments
• Marine sanitation devices– F 2363-06: requires major modification
• Thermal destruction/incineration– F 1322-90, F 1323-01 in place
• Ballast water treatment• Engine air emissions, alternative fuels• Seawater piping anti-fouling?• Solid waste processing?• Hull cleaning?
