Adapted from THE WORLD ICEBREAKER AND ICEBREAKING SUPPLY VESSEL FLEET
for Baltic Icebreaking Management
by Prof. Kaj Riska from ILS Oy.
September, 2008

The list has been done considering each country in itself. This division into countries has been done based on the operational area - not necessarily based on the nationality of the owner. The owner of the vessel is sometimes not clear and sometimes instead of the owner, the operator is mentioned in the list. This uncertainty is evident in the case of Russian icebreaking fleet. The ship length and beam are those at the waterline but some information does not mention whether the data is referring to waterline or length overall. The bollard pull is also mentioned in the list. The bollard pull characterises the ship's ability to break ice - naturally together with a hull form suitable for ice breaking. The bollard pull information can also be related to the force required to keep an AFRAMAX tanker stationary in a storm - at least 100 t bollard pull is required. An AFRAMAX tanker requires two icebreakers to escort her in more severe ice conditions. The bollard pull is usually estimated from the data on power and propellers, and sometimes checked with some other public data. Overall, some caution is necessary concerning the ice breaking capability.
