12.1 Fuel manager overview
The fuel manager provides an estimate of fuel remaining, and
the distance and time which can be travelled before the tanks
are empty. In order to calculate these values, you must configure
the total capacity of fuel available to the engines and log each
time you add fuel. The fuel manager also allows you to set a
low fuel warning alarm which is sounded when the vessel's
estimated fuel falls below a specified value.
The fuel manager page provides current calculation estimates
and controls to enable use of the fuel manager feature.

In order to use the fuel manager you must:
• Connect a compatible engine interface to each engine you
wish to monitor (to provide fuel flow rate data to the network).
• Enter the total fuel capacity of the vessel’s fuel tanks.
• Turn on the fuel manager feature.
• Fill the fuel tanks to full.
• Select ‘All tanks full’.
• Log each subsequent fuel fill whether partial or full.
Note:
Fuel manager estimates the amount of fuel onboard, based on
the user logging each time you fill up, the total fuel capacity,
and how much fuel is burned by the engine(s). Any incorrect
entry could dramatically affect the estimated fuel usage and
capacity which could result in a shortage of fuel. This system
is not a substitute for other types of fuel calculations.
Total fuel onboard is an estimate and will be inaccurate if fuel
fills are not entered, or fuel is used by other sources (e.g.
generators etc.). Estimated distance and time to empty will
be based on the fuel remaining calculation and values do not
include weather/tide effects.
You should not rely on the fuel manager calculations for
accurate voyage planning or in emergency and safety critical
situations.

Fuel logging
You must ensure all fuel fills are recorded using the fuel
manager.
From the fuel manager page:
1. When filling the tanks until full select
All tanks full .
The estimated fuel remaining is reset to the value of your
fuel tanks capacity.
2. When only partially filling the tank make a note of the volume
of fuel added to the tank and then select Add partial fill .
3. Enter the value noted earlier this will be added to your current
fuel remaining figure.
Note: It is recommended that you perform an ‘All tanks full’ fill
up as regularly as possible as partial fills will cause a higher
cumulative inaccuracy in the provided calculations.
