Icebreaker technology has undergone significant advances over the last 25 years. This development has led to building of new generation icebreaking fleet - both icebreakers and ice-capable cargo vessels. This presentation will concentrate on various design aspects in selection of optimum propulsion system for icebreaker vessels:
  • Podded propulsion - Podded systems deliver excellent fuel economy, superior maneuverability, greater flexibility of design, and lower maintenance in a smaller footprint compared to conventional driveshaft propulsion systems.
  • Double-acting ship (DAS) hull design - The DAS with podded propulsion provides better capability than legacy designs while requiring less equipment allowing for smaller, lighter ships which cost less to construct.
  • Onboard power systems - Power distribution systems designed to operate at variable frequency allow diesel generators to run at optimal levels improving fuel efficiency and reducing emissions

The speaker will present recent case projects with modern icebreaker propulsion system e.g. Port Icebreaker equipped with four ice classed Azipod propulsion units and Onboard DC Grid system for power distribution.
