When sacks of grain begin arriving last year at Canadian National's Newfoundland Drydock, some observers wondered whether the company was running a repair yard or a feed lot. Actually, the grain served a useful overhaul function. From past experience with electrically propelled ships in CN's ferry fleet, the yard has found that the best way to clean hard-to-get-at electrical motors is by corn-blasting. The corn has a sufficiently abrasive quality to clean away carbon and other grime, and it is absorbent enough to soak up unwanted oil. The yard used the corn blasting procedure to overhaul 33 propulsion motors on the Sedco 445 offshore oil drilling rig. It was the first time that Sedco Inc. had used Newfoundland Drydock's facilities. In a letter to the yard, it said it was intrigued and highly impressed by the method and the professional way the work had been performed. The yard is still interested in attracting overhaul and repair work from the Soviet fishing fleet. Indeed, it was actively pursuing such a contract last year before action by Canada closed Newfoundland's ports to the Soviets because of repeated violations of international fishing agreements.
