Ice navigation vessel

It may also include adaptations for functioning in freezing conditions, equipment necessary for navigation in ice and anti-icing system for the hull.

The common characteristics of these vessels are the presence of an ice belt or a double hull with its geometry similar to that of icebreakers.

Also, the hull is made of durable materials and is smooth and free of protruding fasteners to reduce friction.

The water intake is designed so that the engine is not clogged with ice, the ship's rudder and propeller are protected from external damage.

[11] And since specialized icebreakers are also actively used for transport purposes within their capabilities, the term “icebreaker-transport vessel” is often applied to them too.

[10] Compared to conventional icebreakers, vessels of this class can overcome ice hummocks more efficiently due to their greater mass.
