INCENTIVIZED SHIPBOARD
ENERGYCONSERVATION
(a new approach to save energy)
BY
NAVAL SEA SYSTEMS COMMAND
INCENTIVIZED ENCON• CNO Approved Incentivized ENCON in FY 94
• CPF Pilot ENCON in FY 95-96 - Good results
• CLF approved ENCON - FY 98
• Opportunities exist to save 10-15%
• Ships received awards quarterly as augmentedOPTAR fund
• All hands receive benefits: coveralls, special tools,computers, consumable matls, etc.
• No additional reporting burden to ships - usingexisting monthly NEURS
AWARD CALCULATION
• Baseline: NEURS 3 years avg (FY96-98) fuelrates in bbls/hr for UW and NUW
• Actual Usage: Quarterly fuel rates frommonthly NEURS report
• Fuel Saved (bbls): [Baseline - Actual Usage] xQtr Hrs
• Awards: 50% Fuel Saving (bbls) x Fuel Cost ($)
NOTE: Awards depend on the overall CLF ships fuel performance and awardfunding availability
ENCON TASKS
• Program materials to ships (NAVSEA)
• In-port ship briefings (NAVSEA)
• Fund and schedule underway training (CLF)
• Underway training (NAVSEA)
• NEURS data/reports (CLF)
• Quarterly Analysis, Report &Recommendations (NAVSEA)
• Quarterly awards to Ships (CLF)
SECAT UNDERWAYTRAINING
• Ship must have Fuel Meters.
• MACHALT 370A - Contact ISIC/Port Engineer
• NAVSEA provides ship training per ISIC request andfunding
• SECAT needs 3 days underway (2-3 hrs a day)
- Bridge yields temp. shaft control to Engrg.
• SECAT is on non-interference basis
• Use Energy Conservation Assist Program (SECAP), a
self-help program, until team visit. Download SECAPfrom web site below:

ENCON Tips (All Ship Types)
• Use the Guide for Energy Conservation (Fuel Economy)Shipboard Application (SL101-AA-GYD-010)
• Establish aggressive awareness training program
• Promote ship energy awareness• Establish active focal point as ship energy manager
• Fuel and water usage in POD or on 1 MC
• Recognize achievements
• Conduct zone inspections
• Steam and water leaks
• Lagging
• A/C boundaries
• Lighting
ENCON Tips (All Ship Types cont’d)
• Energy conservation an all hands evolution• Planning ship’s movements
• Conducting operations
• Standing watch
• Support required from Higher Authority• Allow ships to use most economical speeds for transits
• Allow for ships not having “old-style” redundancy
• Reward ships for fuel savings
ENCON Tips (All Ship Types cont’d)
• Use fuel consumption curves• Not just a drill
• Powerful analysis tool to:• Alert operators to adverse trends
• ID performance differences in major components
• Determine effects of different machinery alignments
• Provide a check point to assure that the most energyefficient machinery alignment is being used
Gas Turbine Ships Tips
• Trail shaft
• Split plant
• Drift (if feasible)
• No Prairie/ Masker bleed (operationalconsiderations allowing)
• Minimize excessive speed changes
• Minimize unnecessary rudder angle and coursechanges
Gas Turbine Ships Tips (cont’d)
• One GTG
• Keep propeller and hull clean
• Water wash main engines
• Keep air filters clean
• Balance horsepower between shafts
• Keep propulsion plant well maintained
Gas Turbine Ships Tips (cont’d)
• Keep Ship’s Force involved• A/C boundaries
• Lights off
• Don’t waste hot water
• 100 kW=7.5 GPH
• Regularly collect, review and act on data
Steam Ships Tips
• Single boiler cross connect
• Trim excess combustion air
• Use electric auxiliaries
• Minimize redundant auxiliaries
• Secure Main Circ Pump ASAP
• Use minimum SSTGs
Steam Ships Tips (cont’d)
• Ensure no simultaneous Auxiliary Exhaustmake up and dump
• Keep propulsion plant well maintained• Watch valve maintenance
• Keep Ship’s Force involved• A/ C boundaries
• Lights off
Steam Ships Tips (cont’d)
• Keep propeller and hull clean
• Use acceleration/ deceleration tables
• Minimize unnecessary rudder angle and coursechanges
• Regularly collect, review and act on data
Diesel Ships Tips
• Single engine/ trail shaft
• Operate engines within efficiency range of 60-90% tobenefit from best compromise between fuel economyand engine performance
• Keep propeller and hull clean
• Use minimum SSDGs
• Keep propulsion plant well maintained
• Keep Ship’s Force involved
• Lights off
• A/C boundaries
Diesel Ships Tips (cont’d)
• Use fewer engines at higher loads
• Monitor engine performance; take appropriate action
• Keep intake filters clean
• Maintain blowers/ turbochargers
• Maintain proper fuel quality
• Keep waste heat system clean
• Keep lube oil clean
MAJOR MILESTONES
• Updated energy guide
• Provided SECAP software on internet forships to do curves
• Prepared quarterly reports to CPF and CLF
• Briefed ships in port
• Prepared NEURS reports for CLF, CPF,Reserve and MSC ships
• Supported SWOS instruction
ACTIONS (to improve results)
• FUEL OIL METERS (CNSL/FTCLANT)– Ship force needs display of fuel consumption rates to monitor and
improve performance
– Installation (only few ships had MACHALT installed in FY 98)
– MACHALT Program must receive a high priority of CLF
• UW SECAT TRAINING(CNSL/NAVSEA)– Only 5 ships had UW training. Only 2 ships so far this FY.
– CNSL to schedule more ships (we have fund for 10 ships)
• INCENTIVES (CLF)– Continue with 50% incentive
• IN-PORT BRIEFINGS (NAVSEA)– Complete all ships in-port briefings
ACTIONS (Cont’d)
• ENCON SEMINARS/WORKSHOPS (CNSL/CLF/NAVSEA)– Conduct during Scheduling Conference (2 a year)
– 2 per year so that 6th flt & 2nd flt ships have opportunity to attend
– Good initiative because of continued crew change over.
• ENCON POCKET GUIDE (NAVSEA)
• ENCON WEB SITE (NAVSEA)
• ENCON VIDEO (NAVSEA)
• ENCON BILLBOARD AT NAVAL BASE GATES (NAVSEA)
• INSTALL STERN FLAP (CNSL)
CONCLUSIONS
• INCENTIVE ENCON SEEMS TO HAVE POSITIVE EFFECT ONSHIP’S BEHAVIORS IN CONSERVING FUEL
• OVERALL FLEET CONSUMPTION RATES WILL BE LOWEREDBECAUSE OF THE FOLLOWING:– More ships added in FY 99
– Continued in-port & underway training
– Incentives
– Quarterly messages (well done messages)
– ACTIONS (to improve results)
CONCLUSIONS (continued)
• LOWER OVERALL FLEET FUEL CONSUMPTION RATES WILLDECRESE HYDROCARBONS IN THE ATMOSPHERECONTRIBUTING TO:– Reduced air pollution
– Reduced Global Warming
– Conservation of Natural Resources
