Finland is heavily dependent on its ice breaker fleet. Finland is one of a very few countries whose ports are all ice bound in a normal winter. The fleet of 9 ice breakers keep more than half of Finland's ports open all winter long. Six of those ice breakers were in port for summer repair and maintenance. The other three are multi-purpose vessels that work for hire in other parts of the ocean for the summer.
