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?
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
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?
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?
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
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
