IACS UR G3 - Polar Class Power
IACS UR G3 minimum propulsion power for Polar Class (PC1 through PC7) vessels - replaces FSICR for Polar Code compliance.
Minimum propulsion power
641kW
Formula, assumptions, and limits
Simplified screening. Full G3 accounts for hull form, bollard pull in ice, and the IACS PC Unified Requirements ice-load distribution. PC1-PC3 needs icebreaker-class hull + full G3/G4 compliance.
