Great Lakes Winter Navigation. Technical and Economic Analyses. Volume V. Ice Strengthening of Ship Hulls Using Steel, Ferrocement or Reinforced Concrete.

摘要

Extension of the navigation season on the Great Lakes necessitated finding the added weight and cost of ice strengthening the hull of existing or proposed ships. Using the American Bureau of Shipping rules Section 29, 'Strengthening for Navigation in Ice,' a design method is developed and a computer program prepared that calculates and compares the added weights and costs of reinforcement along a ship using steel,ferrocement or reinforced concrete for different ice classes and various other parameters.
