Marine Fuel-Consumption Indicator: FUELNAVI
The marine fuel-consumption indicator FUELNAVI (trademark registration pending) enables the ship's crew on the bridge to monitor the fuel consumption of the main engine.
Summary
Conventionally, the fuel consumption of the ship's main engine has been monitored by the chief engineer, who calculates and adjusts it by factoring in other data that affect the volume. He reports the results to the captain or the officer on duty at least once a day. But introducing the marine fuel-consumption indicator FUELNAVI would enable real-time monitoring of the main engine's fuel consumption from the bridge.
The indicator indicates fuel consumption, such as fuel-tons consumed per mile of voyage, from the main engine's flow meter (fuel-flow-rate counter) and the ground-speed figure from the GPS*.
It can also indicate the CO2 tons/mile (CO2 emissions per mile of voyage), which is an environmental-load indicator.
FUELNAVI is also able to analyze the impacts of environmental conditions such as winds and ocean currents by utilizing data on wind direction, velocity, and such.
This marine fuel-consumption indicator is expected to facilitate eco-friendly voyage planning and maneuvering by taking into account the ship's performance features and appropriately setting the main engine revolutions in bad weather conditions.
*GPS (Global Positioning System) is a system that receives radio waves from satellites, measures the longitude and the latitude, and indicates on a map the ship's current position.
Features
FUELNAVI provides the following fuel-consumption indicators:
- Miles/ton (voyage distance in miles per ton of fuel)
- Tons/mile (tons of fuel consumed per mile)
- Miles/kl (voyage distance in miles per kiloliter of fuel)
- Tons/day (tons of fuel consumed per day)
- CO2 tons/mile (tons of CO2 emissions per mile of voyage (estimate value based on the fuel-consumption volume))
Typical Cases
Although there have been no official cases of the indicator being used aboard vessels, it has been installed on a trial basis aboard a containership, car carrier, ore carrier, and crude oil carrier operated by Nippon Yusen Kaisha Ltd. (NYK) in fiscal 2008 to verify the effectiveness of FUELNAVI. After verification of its efficiency, we will increase the number of FUELNAVI-equipped vessels, mainly consisting of vessels operated by NYK or companies in the NYK Group, and modify the indicator as necessary to keep accurate track of ship performance at sea.
