Towing Force Calculator, Formula, TF Calculation

Towing Force Calculator

Enter the values of bollard pull force, BF_(kN) and engine efficiency factor, EF to determine the value of Towing Force, TF_(kN).

Towing Force Formula

Towing force is crucial in determining the total force applied when pulling a vessel or vehicle, considering the bollard pull force and the efficiency of the towing system or propulsion.

Towing Force, TF_(kN) in kiloNewtons is calculated by multiplying the bollard pull force, BF_(kN) in kiloNewtons, with the engine efficiency factor, EF (dimensionless).

Towing Force, TF_(kN) = BF_(kN) * EF

TF_(kN) = towing Forcein kiloNewtons, kN.

BF_(kN) = bollard pull force in kiloNewtons, kN.

EF = efficiency factor.

Towing Force Calculation:

1. The bollard pull force of the tugboat is 30 kN, and the efficiency factor of the towing setup is 0.85.

Given: BF_(kN) = 30kN, EF = 0.85.

Towing Force, TF_(kN) = BF_(kN) * EF

TF_(kN) = 30 * 0.85

TF_(kN) = 25.5kN.

2. The bollard pull force is estimated at 10 kN, and the towing force is 9kN, find efficiency factor due to various conditions.

Given: BF_(kN) = 10kN, TF_(kN) = 9kN.

Towing Force, TF_(kN) = BF_(kN) * EF

EF = TF_(kN) / BF_(kN)

EF = 9 / 10

EF = 0.9.
