Delivering A Crushing Blow
Fennica, Finland's latest class of icebreaker, uses a full complement of
advanced equipment to keep winter commerce flowing
23,000 shiploads of cargo in and
out of Finland each year, nearly 40
percent (9,000 ships) carrying
more than 27 million tons of cargo
takes place during the winter
As the waters around Finland
are traditionally frozen for more
than four months per year, the
government has taken several
steps to ensure the safe passage of
ships and crews during these
harsh months. First, it shuts
down 27 of its 50 ports, thus limit-
ing traffic to the 23 indispensible
areas of the most vital conse-
quence. Second, it has built an
impressive fleet of icebreaking ves-
Icebreaking in the Finnish sec-
tion of the Northern Gulf of
Bothnia — just 100 miles from the
Arctic Circle — can never be con-
sidered routine. Strong winds and
the earth's own rotation can cause
ice to stack up in massive piles,
towering nearly 33 ft. (10 m) above
and anchored 66 to 99 ft. (20 to 30
m) below the water
The activity of Finland's fleet of
eight icebreakers, often working in
close cooperation with their
Swedish neighbors' icebreaking
fleet, are integral in ensuring
Finland's vital transport links
remain open, even during the
harshest winters. Of the nearly
