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
