Bollard Pull

The 'Bollard Pull' is the main criteria of a tug and displays the pulling force expressed in tons. A 'Bollard Pull Test' is carried out under supervision of a classification society. The tug is moored in a port basin with a certain waterdepth, no current and a defined distance to the quay. The tug is connected with his towline to a special bollard ashore. A metering device, which displays the actual pulling-force is interlinked between towline and shore bollard.
