Bollard pull - Wikipedia
Unlike in ground vehicles, the statement of installed horsepower is not sufficient to understand how strong a tug is – this is because the tug operates mainly in very low or zero speeds, thus may not be delivering power (power = force × velocity; so, for zero speeds, the power is also zero), yet still absorbing torque and delivering thrust. Bollard pull values are stated in tonnes-force (written as t or tonnef) or kilonewtons (kN). Estimate… WebHorsepower (hp) is the name of several units of measurement of power, the rate at which work is done. This tool converts horsepower to tons (hp to ton) and vice versa. 1 horsepower ≈ 0.212 tons. The user must fill one of the two fields and the conversion will become automatically. WebBollard pull. marine. The thrust developed at zero ahead speed. Bollard pull is the most commonly used measure of ship-assist tugs performance which have propellers optimized for maximum thrust at close to zero speed. Ships requiring high bollard pull can be fitted with a nozzle, which increases thrust by up to 20-40% compared to open propellers. m\\u0026s logistics nh
