The safe working load of a ship's bollard is calculated based on the maximum load that the bollard can safely withstand without failing. Factors such as the material, size, and design of the bollard, as well as environmental conditions and industry standards, are taken into consideration when determining the safe working load.

Many cities use them to line streets to protect pedestrians. You will find them in parking lots protecting utilities and buildings and marking handicap parking spots. They are also often used in industrial facilites to protect equipment and storage racks.
There are two main types:
Embedded, which means the pipe is buried in the ground. Surface mounted, which means they are anchored to the surface.
There are also "rated" security bollards, which are able to withstand certain size and speed vehicle impacts. Also, a new type, the rebounding bollard, which can be hit and gives a little, then rebounds, to reduce damage.

Originally bollards were used on ships, primarily for mooring, i.e. tying lines to dock.
Today they have two general purposes. Bollards are short vertical posts found almost everywhere to protect assets. Sometimes called simply a "guard post", a bollard may protect buildings, utilities, equipment, or pedestrians. Common examples would be to protect a drive-thru lane at a bank, a fire hydrant in a parking lot, or pallet rack in a warehouse. See some applications here: https://www.slowstop.com/resources/applications. In general, this is vehicle access denial. Some applications call for high strength security bollards, such as in front of embassies and other government buildings.
Second, in Europe the word bollard is used to describe a short vertical sign, often found on a median, directing traffic around the island.

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
