Case Study
“Since installing the FloScan equipment I estimate the vessel has seen an average reduction in fuel consumption in the range of 6-percent. The Point Sur burns approximately 35,000 gallons of fuel annually which equals a savings of 2,100 gallons per year.”
—Barrett Carpenter
Chief Engineer, R/V Point Sur
operated the engines and pitch settings on the propellers. From the gallons per hour feature on the FloScan display we have been able to fine tune the ratio between RPM, pitch, and load on the engines. Utilizing this data we have found the “sweet spots” where fuel economy and speed are maximized. Second, we have seen a reduction in the amount fuel ordered and therefore purchased because of a more accurate knowledge of how much fuel is on the vessel. We often order fuel while out at sea and load it from a fuel tanker truck. Traditional soundings of our storage tanks are not precise while the ship is rolling around in a sea way. After totalizing the numbers displayed on our FloScan fuel computers, we can accurately see how much fuel has been consumed since our last set of correct soundings. This in turn allows us to order fuel more strategically based on current price and how much we need to get us to our next port of call. Since installing the FloScan equipment I estimate the vessel has seen an average reduction in fuel consumption in the range of 6-percent. The Point Sur burns approximately 35,000 gallons of fuel annually which equals a savings of 2,100 gallons per year.”

 

Future Use Of FloScan Systems

“We are in the process of putting together a budget to upgrade the FloScan Fuel Computers on our main engines to include both generator engines,” said Carpenter. “We hope to install the FloNET DataLog peripherals to our system so that real time fuel usage data can be displayed in the wheelhouse to better maintain fuel efficiency under various sea conditions and to automatically log all fuel data for future review. This would allow our mates on watch to further improve efficiency while making adjustments to RPM and pitch.”

Conclusion

Over the past 3½ years the Point Sur has employed FloScan’s most basic system with analog gauge readouts and has used it to monitor only the main propulsion system of the vessel. Since the installation the system the vessel has achieved an average fuel saving of 6% per year in addition to reducing the cost of the fuel purchased during long excursions by helping the crew better track overall fuel consumption and fuel on board. This function allowed them to schedule refueling at ports with the most advantageous fuel prices. With the addition of sensors on the vessel’s generators and upgrading to FloNET networking capabilities with GPS link and DataLog software they will benefit from even more accurate monitoring of real–time fuel consumption to fine–tune engine RPM and propeller pitch settings to match prevailing sea states achieving even greater reductions in fuel usage. The ability to review historic operational data via DataLog software will allow even more flexibility in refueling schedules, review of the operating parameters of monitored engines and generators and provide the ability to generate detailed reports for trips or trip segments with a few mouse clicks.
