Podded Propulsion System Currently Preferred
• Direct drive diesels are hard• Direct drive diesels are hard to fit into a ship with a large moon pool – electric plant provides flexibilityprovides flexibility
• Diesel generators can be “floated” on isolation mounts for low noise/vibration
• Twin azimuthal propulsors give greater maneuverability in ice and open water stationin ice and open water station keeping

S C t ISome Current Issues
Some Current IssuesProcurement• Evaluate “Lease” versus “Buy” Alternative • Assess competitiveness and risks associated with different types of vessel
procurements (performance based/design based/other technical specifications)
Science• Define national needs and opportunities to use suitable international
platforms for future science missionsp• Specify acceptable acoustic criteria
Vessel• Validate the suitability of podded propulsion systems (electro-magnetic
interference and noise)• Determine level of acoustic treatment• Examine methods to reduce emissions from the incinerator (oily waste,
paper, food, plastic, other waste)
