In looking back through my files I note a significant tug arrival in Halifax on December 7, 1982. It was a different scene 40 years ago - large tugs were still used to tow ships and oil rigs, and the arrival of the German tug Oceanic towing the semi-submersible ODR John Shaw was not particulary unsual.
When built in 1969 the Oceanic and its sister tug the Arctic were rated at 14,640 ihp (12,800 bhp) and were the most powerful tugs in the world. They were certainly among the most impressive, as everything sbout them spoke of power and sea-keeping ability. They were built for double duty as salvage tugs and as long distance ocean towing tugs. Their great power could also propel them at 20 knots in order to rush to the scene of an emergency.
