Number of vessels required and crew costs

A2V-Shuttle has twice the passenger flow rate of its competitors,
this means that if the distance is large, one A2V-Shuttle can do
the job of two vessels from a passenger flow rate point of view.
This cuts the crew costs by almost two.
For short trips, boarding time have to be taken into account and
will slightly reduce the passenger flow rate .

Maintenance cost

Standard equipment and lower installed power will lead to
slightly lower maintenance costs than conventionnal shuttles.
The higher passenger flow rate tanslates into smaller fleet and
thus lower maintenance costs.

Fuel costs

Fuel consumption per pax per mile is divided by 2.2 compared
with conventionnal closed taxis while travelling faster.
Considering that one A2V-Shuttle is used 320 days a year, 10
hours a day on a 10 nautical mile journey. 10 hours of operation
means 3 hours of boarding and waiting, 7 hours of travel, 350
Nm per day.
Corresponding fuel consumption is 350x12x0.18 = 750 Liters /
day, 240 000 Liters / year.
Same work with two conventionnal closed taxi 350x12x40 =
1680 Liters / day, 540 000 Liters / year
With a fuel cost of 1$/L, fuel economy represent about
300 000 $ per year.
