RETROFITTING AN ICEBREAKER

When the CCGS LOUIS S. ST. LAURENT was commissioned in 1969, she was then the largest and most powerful conventionally powered icebreaker. Because she no longer met the requirements for icebreaking and fuel economy, it was decided to refit her in order to extend her service life to another 15 years. The major changes implemented were: a new bow and reinforced structure for improved icebreaking; replacement of the propulsion plant for a 40% reduction of running costs; and a new air bubbler system, helicopter hangar, and crane. The modifications are expected to be completed by the end of 1990.
