Bollard pull is the maximum pulling force of a vessel and is important for determining its capabilities. It is calculated by multiplying BHP by propeller efficiency and dividing by propeller speed.
Factors that can affect bollard pull include vessel size and weight, propeller design and efficiency, and external factors.
In ship design and operations, bollard pull is used to determine engine and propulsion requirements and to plan and execute tasks such as towing and mooring.
