Describes the 9 Sept 1969 difficulties of the SS Manhattan in 6-ft thick ice and later in 8-9 ft flat ice and 15-20 ft thick ridges in Viscount Melville Sound. At a speed of 6 knots, the tanker has the capability to break through 40-50 ft thick ice ridges, but breakthrough from a standing stop was impossible without aid from the icebreaker Sir John A. Macdonald. It is anticipated that five icebreakers at strategic points will be required for commercial operations in the Northwest Passage and others in the Beaufort Sea.
