  1. Presenting the next generation in podded propulsion The Compact Azipod propulsion system Ulstein Verft AS 12 – 13.06.01

  2. Compact Azipod system • The Compact Azipod system is the solution which meets the market requirements for the propulsion power range from 400 to 5000 kW. • The target markets are: • ferries • river vessels • offshore vessels • fishing vessels

  3. Compact Azipod system • What’s new • A standardised product series enabling: • series production and cost effectiveness • short delivery time C A D B

  4. Compact Azipod system Electric power transmission and steering gear module • What’s new? • Extremely compact and modular design enabling: • efficient production • shorter assembly time using the “plug and play” principle Strut module Motor module Propeller

  5. Compact Azipod system • Power< 5 MW • Designed for: • Drive Efficiency • Hydrodynamic Efficiency • Serviceability • Short Delivery Time • Quick Installation • Competitive Price Achieved Through: • Modular Design • Low No. of Components • Permanent Magnet Motor • Water-Cooled, PWM DTC Drive • Electric Steering Machinery

  16. Compact Azipod system • Azimuthing thruster superior vs.conventional propulsion • Diesel-electric superior vs. mechanical power transmission • Modular Azipod superior vs. mechanical azimuthing thruster Why Modular Azipod Concept?

  17. Compact Azipod system Why azimuthing thruster superior vs.conventional propulsion? • Manoeuvrability • reduced vessel turning radius • shorter crash stop distance • improved harbour and low speed manoeuvring • Operational safety • No need for separate rudder • less vessel resistance • faster and simplified installation • Improved overall economy

  18. Compact Azipod system • Freedom in overall vessel design • no need for long shaft lines • less structural borne vibration and noise • better power generation redundancy • Improved safety and comfort • Optimal engine loading • reduced exhaust emissions • less maintenance • smaller operating costs • More environmental friendly and better economy Why diesel-electric superior vs. mechanical power transmission?

  19. Simpler concept less parts, less spares less vibration and noise better propulsion redundancy Improved safety, economy and comfort Modular design faster spare part service competitive price less down time in case of grounding Better use of capital Compact Azipod system Why modular Azipod superior vs. mechanical azimuthing thruster?

  20. Compact Azipod system Why modular Azipod superior vs. mechanical azimuthing thruster? • Large Z-drive features: • Sequence start up • cold to full power 1.5 h • warm to full power 0.5 h • stand-by to full power 2 min • Mechanical complexity • > 15 bearings • > 10 oil filters • > 10 oil pumps • large oil quantities (up to 10 m3) • Control complexity • > 20 measuring points

  21. Compact Azipod system • Low exhaust emissions thanks to constant speed diesel generators that always run close to optimum operating point • No oil leaking shaft seals thanks to water and grease lubricated combination seal • Easily adaptable to new energy sources such as fuel cells Environmental Aspects

  22. Compact Azipod system Control system Frequency converters Azipod units Main switchboard Diesel generator sets

  23. Compact Azipod system Generator sets Automation Main switchboards Propulsion transformers Propulsion motors Frequency converters Control Power Distribution

  24. Compact Azipod system Future vision: • Electric propulsion systems will be increasingly applied also in smaller vessels. • The driving forces are: • Environmental Clean power production • Shipyard processes Modularity • Market fluctuations Adaptability and flexibility • Operational Easy to use standard packages

  25. Compact Azipod system Future vision: The introduction of a competitive electric propulsion solution to a market typically dominated by mechanical propulsion will expand the available market. The volume of electric podded propulsion market in the power range below 5 MW will exceed 300 units in 2005.

  26. Compact Azipod system Compact Azipod Benefits - Summary • Saves on service expenses and work • Saves on fuel expenses • Excellent performance in varying conditions • Cuts down exhaust emissions • Does not leak oil into the sea • Pays itself back in the long run

  27. Compact Azipod system Reasons for selecting the Power Plant Concept: • Flexibility in Different Powering situations • Simplifies the service routines • Freedom for the designers to locate the machinery • Low Exhaust Emissions Power Plant Concept Advantages
