Atlantic Willow has its line up near the bow, and Spitfire III is tucked in astern for tethered escort as Dalian Express transits the Narrows. The tug is about to go into a hard move to the ships starboard side and exert about 90 tonnes of pull to swing the stern.
The Cape Sharp Tidal Power project, developed jointly by Open Hydro Ltd and Emera Inc was positioned in the Minas Basin last year, but now needs adjustment and is to be raised off the seabed and barged to Saint John on its own specially built Scotia Barge assisted by the tugs Atlantic Hemlock, Atlantic Bear and Atlantic Fir. There is about a one week window of favourable tides to do the work, so Atlantic Fir may be away from Halifax for some time.
Pull completed, the tug swings back in line with the ship. Note the escort winch is covered to protect it from winter conditions.
In the meantime the more than capable Spitfire III will perform ship docking and escort services in Halifax. Today it assisted the 1000,006 dwt tonne Dalian Express transit the Narrows in a stiff breeze, then turn the ship when it reached Bedford Basin.
Spitfire III leans into the line as it assists in turning the ship in Bedford Basin.
Unique among Atlantic Towing tugs, Spitfire III and its sisters (Atlantic Bear and Atlantic Beaver) are not named for trees. However it is indirectly. During World War II, one of the J.D.Irving businesses made specialty aircraft plywood, used to build Mosquito and Spitfire aircraft among others. K.C.Irving, himself was a World War I member of the Royal Flying Corps and was a keen pilot in peacetime, once landing his own float plane on Halifax harbour.
