2. Submarine Energy
Powered by an alternative energy source (nuclear), submarines are participating ships of the 2016 Great Green Fleet deployment
Submarine fuel use is closely tracked to meet or exceed planned life expectancy
In port energy use is minimized by powering down systems not needed for habitability and safety
Los Angeles class submarines were built with 30-year cores. Virginia Class submarines are outfitted with life-of-ship cores. Fuel use during deployments, operations, and exercises are all planned and tracked to maximize fuel conservation.
Nuclear reactors are shut down while in port. Regardless, even while pierside, submarines are operated in strict accordance with established operating procedures.

3. Current Practices & Efficiencies
In port, major systems are de-energized or operated at reduced load
Secured: Radar, Sonar, Atmosphere Control, Fire Control, Lube Oil Systems, Laundry
Reduced: A/C system reduced to ½ capacity
Regular heat exchanger cleaning
Hull cleaning at every drydocking
Ship transits are planned at most energy efficient speeds
VIRGINIA Class and follow-on classes have life-of-ship cores
Adherence to regularly scheduled maintenance and written operating procedures automatically classify submarines as energy efficient.
LED battle lantern and bunk lights are being installed during availabilities. LED battle lantern install is complete for a CSL units. LED bunk light install is ongoing.

5. Discretionary Trade-Space = 1.4 kWh
In-port Submarine Electrical Trade-Space
Submarines have little discretionary energy use as measured in <1% of total usage. Habitability and environmental controls are adjusted according to manning and posture. Energy use for engineering and combat/network systems are relatively constant throughout a submarine’s in port period.
Typical Discretionary Loads (120V receptacles)
Crew Televisions/DVD/etc : Wh
Personal Electronic Equipment: Wh
Misc Electronic Equipment: Wh
Discretionary Trade-Space = 1.4 kWh

6. Submarine In-port Energy
Energy Utility Reports
Meters installed at Norfolk and Kings Bay submarine piers
Norfolk-receiving reports
Kings Bay-NAVFAC installing communication software
Distributed by TYCOM to unit COs via Squadron
Provides awareness of energy usage and cost
In port submarine energy usage is visible throughout the entire chain of command. SUBLANT receives monthly in port submarine energy usage reports from NAVFAC , analyzes the data, and pushes the reports, analysis, and requests for information (when applicable) to the squadron. Squadron sends the information to each submarine ensuring that every CO is aware of his energy usage.

7. Submarine In-port Energy
This is a chart of actual in port submarine electricity usage. Note that usage above the maximum expected variance is investigated by TYCOM and Squadron. Analysis of CY 13 & 14 data shows that an average SSN submarine utilizes 22,500 kWh of electricity in a month and all excursions above the maximum expected variance were justified by operational requirements. Virginia Class submarines use slightly more electricity than Los Angeles due to technology differences.

8. Future Practices & Efficiencies
Metering at Groton submarine base
Biofuel substitute for emergency diesel engines
Low impact antifoul coating on SSGN topside surfaces
Reduces drag
Reduces in-port hull cleaning
Groton, Kings Bay, and Norfolk are the three submarines bases on the Atlantic coast. Data analysis and communication between TYCOM, Squadron, and submarine will be similar to Norfolk once metering begins in Groton.
NAVSEA has developed and is currently testing biofuel use for submarine emergency diesel engines.
NAVSEA, BUMED, and TYCOM are jointly evaluating the use of non-copper containing antifouling paint on the topside of SSGN submarines. We anticipate that application of this paint will reduce energy and fuel use by decreasing hull cleaning frequency and improving hydrodynamics.

environments
While it is obvious that submarines are different than surface vessels, most important is the difference between operating environments. Once submerged, submarines disappear, becoming silent and operating independent of outside communication. Because submarines contain a nuclear power plant and operate beneath surface, there is little margin for error when it comes to safety of ship and crew. Requirements for every operation and equipment use is detailed in written procedures.

17. Procedural compliance is the key to Submarine Force’s success
Submarine Culture
Procedural compliance is the key to Submarine Force’s success
A culture of rigorous adherence to procedural compliance allows submarines to operate most efficiently and safely per design
From the first day of submarine training, all Submariners are taught the importance of strict procedural compliance. Reinforcement of this imperative continues throughout their careers.
Manufacturers, technical warrant holders, and other experts develop and provide equipment operating procedures that maximize utility, safety, and efficiency. Submariners are required to follow those procedures.
