Bollard Pull Analysis BS22
Understanding the Bollard Pull of their vessel is essential for planning and executing towing operations safely and efficiently. It ensures that the vessel can handle the required loads and perform the necessary maneuvers without risking damage or accidents. PT. Simsar Reka Gemilang was requested by Client to make a report regarding Bollard Pull calculation.
Bollard Pull is a measure of the pulling or towing power of a vessel, typically used for tugboats and other maritime vessels. It represents the maximum force a vessel can exert when its propulsion system is at full power, but the vessel itself is stationary. This force is measured in tonnes or kilonewtons (kN).
The calculation involves measuring the force exerted by the vessel on a shore bollard (a sturdy post on a dock) through a towline. The formula used is:
![\[ \boxed{Bollard Pull (tonnes) = \frac{Engine Power (kW) \ast Propeller Efficiency \ast 0.101972}{9.81}} \]](https://simsargemilang.com/wp-content/ql-cache/quicklatex.com-07a7c318e6ed17abee20ad7929c87c8c_l3.png "Rendered by QuickLaTeX.com")
Why is Bollard Pull Important? Yes, it is for towing operations which the capability of a tugboat to tow other vessels determined, such as ships, oil rigs, or barges. Besides that, it is for port maneuvering, to ensures that tugboats can safely guide larger vessels into and out of ports. Other is for offshore operations as it is crucial for positioning and moving floating structures like oil platforms. The last is for Safety reason to get accurate Bollard Pull calculations help prevent maritime accidents by ensuring vessels are used within their safe towing capacity.
