It is a "bollard." The hawser (rope) is attached to the bollard to anchor a ship in position at a pier or wharf.
To calculate the safe working load of a ship's bollard, you need the working stress and the force applied. These two will help you compute the safe working load.
The Bollard was created in 2005.
Alan Bollard was born in 1951.
A bollard is a short vertical post used to block vehicles, to prevent travel in an area or to avoid damage to something behind the bollard. Bollard covers protect the bollard from superficial damage and weathering, and are not a particularly new technology.

Safety bollards are found throughout industrial plants and warehouses protecting loading dock doors and wall, equipment, pallet rack, and employees.
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
According to Wikipedia, a bollard is a sturdy, short, vertical post. The term originally referred to a post on a ship or quay used principally for mooring boats.
