Bollard pull trials are conducted in order to determine the static pull that a tug is able  to employ in operating conditions. To enable fair comparison, the trials are not  performed in typical operation conditions (e.g. shallow and confined harbour basin),  but in conditions as close to ideal as possible, i.e. in conditions where the  environmental and external effects are minimised. 
 A “bollard test” or “bollard pull test” is a physical test typically performed by fixing a board to a “bollard” on shore with a hawser and measuring the “pull” with a load cell.

Our  introduces the minimum requirements for trial site, vessel state and  environmental conditions as well as the actual procedures for conducting the trials  and definitions on bollard pull, to be used on tugs.
