1. At anchor, at anchorage number 10, Louis powers up the bubbler.
CCGS Louis S. St-Laurent has sent the day in Bedford Basin doing ice bubbler trials.
With plus 12 degrees C (record high) temperatures in Halifax, there is no ice to bubble, but the ship is more comfortable doing the trials than it would be out at sea with gusts of up to 100 kph.
The system, consisting of a 2,000 hp thruster forces water up on either side of the vessel reducing friction and to prevent ice from adhering to the ship, increasing its efficiency through heavy ice.
2. The ship then upped anchor, moved to anchorage number 8, anchored again, and powered up the bubbler once more.
