Benefits of DF Electrical Propulsion for LNGC
High efficiency over whole speed range
Lower Fuel Consumption
Environmental friendly
Lowest Emissions
Less total installed power.
Use the same power plant for propulsion and cargo handling.
Flexibility in location of equipment
Space saving and optimizing of ship design.
Low pressure Gas Fuel Supply (5-6 bar)
Safety
Variable speed drives
Ensures that full torque is available for the whole speed range and full power for negative RPM => improving maneuverability and crash stop situations.
Redundancy in electrical equipment:
Maintain approx 70-90% of full speed with single failure.
Perform maintenance at normal operation.
Fuel Flexibility fitting with future energy situations

Hydrodynamics with Azipod propulsion
ABB Group February 19, 2014 | Slide 43
Optimum wakefield due to Pulling propeller Lack of shaft line and shaft
brackets etc.
Location of the pod unit
, Due to power plant principle and lack of long shaftlines there is freedom to optimize the hull form
No separate stern thrusters and rudders

( ) Stern First Operation (Double Acting Ship)
ABB Group February 19, 2014 | Slide 44
Propeller suction effect removes ice blocks from the ridge keel and breaks the
ridge by removing the foundation of the ridge
Capable to operate without ramming
Propeller induced water flow lubricates the ice/snow and reduces friction to the
ship hull
- - Possible to optimize stern for icebreaking and bow for open water
In stern first operation bigger clearance between hull and propeller tip
Less need for assisting icebreakers

/ Challenge
( 21,5 ) Two propeller design points that are far away from each other (Bollard and 21.5kn)
, , .. Vessel picks up cargo from very demanding arctic areas where independent operation in ice is necessary -> high Ice class
, / Thus high thrust in icebreaking conditions needed and also high speed in transit in open water conditions
90% , 90% of operation in ice free waters means that fuel economy is very important
: Two design conditions were selected:
15 ( = 0 ) 15MW at bollard pull condition (Vs=0kn)
21.5 (15 ) Trial speed 21.5kn (15MW)

Design process
Initial geometry was created from existing project
Design made for side Azipod
Procal Procal software was used to analyse:
/ Efficiency estimation
Loads
Cavitation
Model tests
Design verification
, Open water only, without ship hull
Propeller design is a generic design and will be updated according to each vessel design
The goal of this project was to design a propeller that can operate succesfully in ice free water with high speed and efficiently in heavy ice conditions
! Goal was reached!

Azipod VI2300L Technical advantages of upgraded Azipod VI2300L
Increased hydrodinamical efficiency
, big propeller, high torque
High torque and power in ice-going mode
max. overtorque is needed for safe and efficient operation in ice
Increased stability in course keeping
long pod and strut
Most of operational possibilities improved
More freedom in optimization of middle propeller
