![]() ![]() Modern ships are, almost without exception, built of steel. However, they provide a detailed starting point for analyzing a given ship's structure and whether it meets industry common standards or not. Almost always those methods will give conservative, or stronger than precisely required, strength values. These methods often give a quick and dirty way to estimate strength requirements for any given ship. Ship classification societies such as Det Norske Veritas, American Bureau of Shipping, and Lloyd's Register have established standard calculation forms for hull loads, strength requirements, the thickness of hull plating and reinforcing stiffeners, girders, and other structures. The typical test case for quick calculations is the middle of a hull bottom plate section between stiffeners, close to or at the midsection of the ship, somewhere midways between the keel and the side of the ship. ![]() The total load on a particular section of a ship's hull is the sum total of all primary, secondary, and tertiary loads imposed on it from all factors. This diagram shows the key structural elements of a ship's main hull (excluding the bow, stern, and deckhouse).
