Ramming the Ice: Icebreaker Propulsion

, , , , , , , ,
This beast bares TWO nuclear reactors, with over 60 MW of propulsive power driving through anything in its path! Discover why we need so much power for an icebreaker.

Breaking the Ice: Icebreakers

, , , ,
How do icebreakers crack through the ice and come out undamaged? We still use the same techniques from over 50 years ago. Why do they work so well?
Propulsion Classification

How Propulsion Works: Classifying Ship Propulsion

, , ,
No doubt, the math of propulsion devices is complicated. But it is all the same physics. By dividing each of these devices into their essential tasks, we find new opportunities. New methods of propulsion from different combinations of old tricks. Insight into this continuum allows us to better classify marine propulsion and dissect past successes to search for new combinations.
