Resistance and Propulsion Articles

Resistance estimation for a vessel is a fundamental exercise in design of the vessel. Resistance is a property that depends on the vessel’s shape and form. A conventional ship-shaped vessel with a bulb will have completely different resistance characteristics compared...

Introduction A keyless propeller, as the name implies, requires no key for fastening the propeller on the cone of the propeller shaft. How is the torque then transferred to the propeller? The torque is transferred by the friction between the propeller and the...

How to use empirical formulas to estimate the resistance of a Ship Resistance estimation holds immense importance in the design stage of a vessel. Based on the results of the resistance estimation of a vessel, the selection of the right propulsion system is done....
