| Part of a series on vessels'
Ice frames are additional frames, between framespaces, of an ice-classed vessel. These frames are used throughout the ice belt to decrease the panel size of unstiffened/unsupported plate, allowing for a reduction in plate thickness while providing the strength needed to deal with ice pressures. Ice frames can be run longitudinally, however they are almost universally transverse. Classification societies generally require one end of the frame to terminate on a deep stringer outside of the ice belt.
