Knowledge Products:


  • Specifications & Standards:One of the primary transition products resulting from technology development, these documents are the primary enablers for ship and system designers to incorporate and procure products and provide them to the Fleet. In partnership with SEA 05, Program Executive Office Integrated Warfare Systems (PEO IWS), and NSWCPD, ESO is working to develop new DC electric interface standards. The Command is currently reviewing and updating many military specifications, standards, and handbooks, and employing commercial standards and specifications in an effort to reduce cost while maintaining military effectiveness. Specifications and standards play a vital role in realizing next generation integrated power and energy systems.
  • Power System Modeling & Simulation: Working together with NSWCPD Code 32, ESO has developed and maintains a library of validated component and system models for design and analysis of power and energy systems. ESO is leveraging significant Office of Naval Research (ONR) investment at FSU CAPS in order to obtain early insight into the effects of high power and energy mission systems on ships electric power systems. This low-cost approach to testing is referred to as Power Hardware In the Loop (PHIL). PHIL includes development of component computer models that simulate and emulate actual operating machinery components and shipboard power and energy systems. PHIL testing replaces component models with hardware once hardware development is complete. PHIL testing costs less than full-scale hardware system testing, shortens development time, and affords the opportunity to identify and mitigate risks in a deliberate fashion from specification development to computer model development to hardware development resulting in a more affordable and robust end product.


  • Naval Power & Energy Systems (NPES) Technology Development Roadmap (TDR): - ESO developments are aligned with the Navy's 30 year shipbuilding plan via the Naval Power and Energy Systems Technology Development Roadmap, which outlines the way ahead for future developments and provides a basis for coordinated planning and investment by the Navy and private industry. The NPES TDR responds to the emerging needs of the Navy and, while specific in its recommendations, it is inherently flexible enough to adapt to changing requirements. The TDR is updated biennially.

  • Ship Operating Profiles: Ship design and program management professionals within corporate NAVSEA use notional ship operating profiles for design and other purposes. PMS 320, in performing various propulsion plant alternative studies, determined that ship operating profiles with greater detail and based on actual, in service fleet data would have greatly enhanced study results and be more applicable to the operational Fleet. To date, ship operating profiles for DDG 51, LPD 17, LHA 1, LHA 8, and LSD 41 have been developed.
  • Uninterruptable Power Supply (UPS): Studies are underway to explore the potential advantages of reducing the proliferation of Uninterruptible Power Supplies (UPS) aboard Navy ships. A study is currently underway investigating UPS consolidation on an existing amphibious warfare ship. Potential benefits include reductions in total ownership cost by reducing costs associated with UPS acquisition and maintenance while providing acceptable continuity of power and meeting survivability requirements.
