3. ELECTRIC PROPULSION DIESEL
Auxilia is a RTN brand that identifies two types
of marine electric propulsion systems: auxiliary
propulsion system and main electric propul-
sion system.
For the commercial vessels, Auxilia offers an
auxiliary propulsion system consisting of e-
motors, drivers, PMS (Power Management Sy-
stems) gensets and control levers. Furthermore
Auxilia could supply all components of the pro-
pulsion system in a complete package (reduc-
tion gearboxes, shafts and propellers or POD
systems).
The electric motor, up to 200 kW, is solid
mounted with the diesel engine housing (direct
mounted). For the versions over 200 kW only
the clutch is coupled to the diesel engine but
the e-motor is connected to the main engine
through a shaft and installed on rigid mountings
(remote mounted). Both versions act on the
same shaft and on the same propeller; the
clutch between the e-motor and the diesel en-
gine permit to disengage the main engine from
the propulsion system when the e-motor is on.
Auxilia can be used in alternative to the main
diesel engine. With the clutch disengaged, the
e-motor can take the ship from the harbour out
into the open sea (shutdown of main engines,
power from gensets or batteries) and cruising
at 6-10 knots with excellent fuel economy, low
emissions, faster accelerations.
If the captain then decides to go at full throttle,
he will deploy the full power of his diesel engi-
nes. The clutch will engage and the combustion
engines take over the ship’s propulsion. During
this phase the e-motor can works in two pro-
pulsion modes: as a generator recharging the
batteries or producing electricity for the ship
load or in booster mode to increase the speed/
acceleration.
For long distances when cruising at moderate
speed, in order to save fuel (and CO2 emissions)
the captain may shut down one diesel engine
and drive the second propeller using the electric
motor (e-shaft mode with two shaft line).

4. • redundancy of propulsion
• longer engines service life and
consequently reduction of
maintenance costs
• easy installation
• possible retrofit
• universal connection with all
gearboxes (V-drive, Inline,
freestanding) and propulsion
systems (POD, CPP,WJ)
• sea water cooling (easy piping)
• change of the propellers sense of
rotation without load pick on the
e-motor

CONSUMPTIONS
• cruising until 10 knots with
excellent fuel economy
• economic navigation with “e-shaft
mode” (two propellers with only
one engine running).
EMISSIONS
• significantly CO2 and NOx
reduction
• maneuvering in harbour without
emissions.
• minimal emissions with gensets
LOW SPEED
• easy dynamic position mode (DP)
especially with FPP
• patrolling at low and very low
speed (below idle engine speed)
with excellent fuel economy
COMFORT
• low noise and vibrations
• night cruising in full comfort
