ARCTIC STAR OPERATING MANUAL
NW Explorations | 29
Arctic
Star’s cruising range is 350 to 400 nautical miles running at 10 knots with a 10% reserve.
There will be no need to fuel up on a one-week charter until your return to the harbor.
6.2.1
Fuel Manifold
The fuel manifold is located at the aft end of the
engine room under the generator and is used to direct
the flow of diesel fuel from the tanks, through the
filters and to the engines. The engines do not use all
the fuel that is supplied to it, some of the fuel is
returned to the fuel tanks. The fuel manifold also
directs the return flow. For simplicity, we keep all the
fuel valves open. This allows the fuel to be supplied
from both tanks, and to be returned to both tanks and,
for fuel in both tanks to remain at equal level. Please
be sure that all valves are open on the fuel manifold.
6.2.2
Fuel Level
Every few days you may wish to check the fuel tank
level; to do this, open the valves at the top and
bottom of the fuel sight glass and the level of the fuel
in the tube will equalize with the level of fuel in the
tank. On Arctic Star, the valves are push button valves
and a little sticky. This procedure takes two hands,
one at the top and one at the bottom.
At 10 knots your cruising range will be 350 to 400
nautical miles so, if you are taking a 1-to-2-week
charter, you will not likely need to refuel until the
end of your charter.
Note:
NW Explorations can fill the fuel tanks and empty the waste tank at the end of your
charter. Let the charter manager know if you choose this service prior to the end of your trip.
This convenience will save you time at the end of the charter. You will be charged for the fuel
plus a service fee.
All valves on the fuel manifold should be
kept in the open position as shown above.
The 300-gallon fuel tanks have a sight-tube
that indicates the level of fuel. You need to
push in the valves at the top and bottom
get an accurate reading.
