WebJul 13, 2024 · A ship’s hull is basically made up of bent plates welded together. If these plates are not stiffened, the bending moments on the plates due to the loads may exceed the value of stress that can be withstood by the material, and hence cause failure. So, the plates are stiffened (or their section modulus is increased) by adding stiffeners to them. 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.

Hogging is the tension that a ship’s hull or keel bears, causing the center or keel to bow upward. Hogging, often known as “hog,” is a semi-permanent bend in the keel created over time by the ship’s center being more buoyant than the bow or stern. therrien homesWebFeb 6, 2024 · I was in the process of throwing out the table mount when I noticed a few parts that may be useful for plank bending.
