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
What is bollard pull cpacity for anchor handling tug is it same as winch line pull?
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

What is formula for calculating the Bollard pull of a ship?
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
What mathematical formula do architectural engineers use in calculating the bollard pull of a tug boat?
Engineers use almost all mathematical formulas that exist, since engineering covers the entire range of science. Normally we use a simple formula if tug has amain engines and standard 4:1 gear box : we use formula of 1/ 10 if you bhp is 900 , you get Normal 9 bollard pull how ever if you have Kort nozzles & K type propeller you can multiply by 1.3 henf 9 x 1.3 = 11.7 approx 12 you have to do Bolard pul test wiht Steel wire rope as it has no Give and use a standard length of 120 meters sea condition has ot be "CALM " or Still normally one hour after high tide angle of rope has to not over 2 - 5 degrees over 120 meter never do Bollard pull test with Nylon ropes or length below 120 meters the test is then invalid you can get very high bollard pul if you increase Reduction gear by say 16 : 1 and use large Pitch and Diameter propllers wiht slow speed engines max 100 rpm - 120 rpm call me if you need advice
