1) First up draw BODY PLAN for your tug boat with reasonable number of stations..
2) Find the sectional areas (of each station) from the body plan till the required draft...
3) Then using simpson's rule,simpsonize the areas and find the volume...
4) Then find the summation of volume.. this gives the volume of displacement..
5) We can hence find bollard pull using the relation
Bollard pull = ((Displacement * 60)/1,00,000)+ 40
100
anchor handling winch and winch wire is designed based on bollard pull requirement. winch wire breaking strength is 2 to 2.5 times of bollard pull force. anchor winch brake holding is 1.5 time of bollard pull or 80% of wire breaking strength

It can be, meaning a sharp pull, or a tugboat. Tug is also a verb.
A bollard pull test should typically be done annually to ensure that the tug or vessel's towing capability is in accordance with industry standards and regulations. Additionally, it may be required to be done after any major repairs or modifications to the vessel.

The term tug job refers to an employee that works on a tug boat. These jobs daily duties include helping maneuvering larger boat's with the tug boat.
Greetings There are basically two approaches for calculating Required Bollard Pull of a Tug for towing a Barge or a Ship. The first method is to determine the frictional resistance, wave-making resistance, wind resistance, current resistance and towrope resistance for a given tow speed and sum all these up and depending on the units used convert the same to BHP, after taking an efficiency factor. The second method is to determine the total force (which includes wind resistance, wave resistance, current resistance, all at zero tow speed), that is the force required of the Tug to ensure that it can hold the Tow in a given envriornemental criteria. As per IMO Guidelines for Safe Ocean Towing, a 5 metre wave, 40 knot wind and 1 Knot current is taken. Kind regards Tony Fernandez tony.fernandez@braemarfalconer.co.in
Donald's tug boat is in Ostown, but it is sunken in thiner.
