If static force is applied to a sheet of ice it will flex slightly before suffering a catastrophic failure. Since the ice will bend slightly when any capable vehicle travels on ice-covered water, it follows that travelling at some critical speed may impose sufficient flexing of the ice sheet to cause resonance, and this may result in positive feedback effectively amplifying the oscillation ...
Petroleum exploitation companies operate a fleet of Ice Breaking Emergency Evacuation Vessels (IBEEV) on the Caspian Sea, to service the extensive oil fields there. [2] [3] [4] The vessels are designed to evacuate up to 338 individuals per trip. They are designed to function using compressed air to power their engines, if they are passing ...
