For a ship in motion, additional bending moment is added to that value to account for waves it may encounter. Standard formulas for wave height and length are used, which take ship size into account. The worst possible waves are, as noted above, where either a wave crest or trough is located exactly amidships. See more The strength of ships is a topic of key interest to naval architects and shipbuilders. Ships which are built too strong are heavy, slow, and cost extra money to build and operate since they weigh more, whilst ships which are built … See more The hulls of ships are subjected to a number of loads. • Even when sitting at dockside or at anchor, the pressure … See more Modern ships are, almost without exception, built of steel. Generally this is fairly standard steel with yield strength of around 32,000 to … See more • Naval architecture • Shipbuilding • Bulkhead (partition) • Double bottom See more Ship classification societies such as Det Norske Veritas, American Bureau of Shipping, and Lloyd's Register of shipping have established standard calculation forms for hull loads, … See more While it is possible to develop fairly accurate analyses of ship loads and responses by hand or using minimal computer aids such … See more • Ship Structure Committee See more WebFig. 6.3 Hull girder stresses over a ship section of a twin decker general cargo ship due to a sagging bending moment For the sagging bending moment M V, the hull girder stress at the deck is compressive and at the bottom is tensile. The magnitude of the deck and bottom stresses depend on the magnitude of the section modulus at the deck and bottom
