Case Study 1: A Major Cruise Line

A major cruise line has agreed to engage in fuel trials utilizing EcoEmissions once a mutually accepted SAE test protocol has been established. Vessels in this size class can require over 2,475 gallons of diesel fuel (HFO) per hour and usually operate 3,500 hours a year.

Per Ship

Fuel Consumption: 8.6 million gallons
Estimated Fuel Cost: $12,740,000 per year ($455/M3)
Estimated Fuel Savings @ 3%: $ 382,000 per year

With a fleet of 10 ships, the estimated fuel saving can very quickly approach $4 million and CO2 emissions can be reduced by over 32 thousand tons per year.

The proper catalyst rate for Heavy Fuel Oil is currently being developed and is expected to show a reduction in fuel consumption in the 3 – 5% range. Other vessels operating on lighter fuel oils have already achieved reduced fuel consumption results in the 6 – 8% range.

Case Study 2: CRUISE WEST

Cruise West engaged Eco Emissions for fuel trials on the cruise ship Endeavour. These trials were recently completed successfully.

Per Boat

Fuel Consumption: 300,000 Gallons per year
Fuel Cost: $780,000 per year (ULSD Fuel @ 2.60)
Estimated Fuel Savings @ 8%: $ 62,400 per year
Results: 9.3% in fuel savings; a reduction of 348 Tons of CO₂ from the exhaust from this ship alone

EcoEmissions is currently in the process of outfitting Cruise West’s fleet of 21 vessels.

Projected Annual Net Savings for Cruise West fleet: $823,200

Case Study 3: WESTERN TOWBOAT

Western Towboat is a family owned business that specializes in container barge transportation. Their primary work is moving freight to Alaska for Alaska Marine Lines. Each towboat burns 140 gallons of diesel per hour and operates 5,000 hours a year.

Per Boat

Fuel Consumption: 700,000+ gallons per year
Fuel Savings: 45,500 gallons per year
Estimated Fuel Savings: $102,375 per year

Western Towboat owns 17 ships, which would provide them with annual fuel savings of $1,740,375.

The annual CO₂ reduction for this vessel would be over 509 tons per year. Across their entire fleet, this would represent a reduction of 8,657 tons of CO₂ .

Case Study 4: VICTORIA STAR 2

This medium-sized passenger ferry operates between Bellingham, Washington and Victoria, British Columbia. It has three older 12V71 Detroit Diesel engines that are noted for dirty black smoke exhaust. This boat uses 23 gallons of fuel per hour and operates 1,200 hours per year.

Fuel Consumption: 83,000 gallons per year
Fuel Savings @ 9.3%: 7,905 gallons per year
Estimated Fuel Savings: $23,100 per year

This system will eliminate 81 tons of CO₂ exhaust each year.

Case Study 5: MILES SAND AND GRAVEL

Miles Sand and Gravel is well known and respected in the Pacific Northwest. They operate approximately 50 Caterpillar 988G front-end loaders with 3456 engines.

Per Loader

Fuel Consumption: 32,500 gallons per year
Fuel Savings @ 9.0%: 2,925 Gallons per year
Estimated Fuel Savings: $7,020 per year

This system will eliminate 32.7 tons CO₂ exhaust per Front End Loader and with 50 loaders that is 1,635 tons of CO₂ eliminated each year.

Case Study 6: A LARGE MINING COMPANY

This Utah-based company operates 61 haul trucks ranging from 240 to 320 ton. These trucks operate approximately 7,000 hours per year and the average fuel burn is 60 gallons per hour each.

Per Truck

Fuel Consumption: 420,000 gallons per year
Fuel Cost @$2.40 per gallon: $1,008,000 per year
Estimated Fuel Savings @ 8.0%: $80,640 per year

This system will eliminate 376 tons of CO₂ exhaust per truck, and with 61 trucks that is 22,293 tons eliminated annually from just one mine.
