Bollard Pull Meaning and Tug Power

The conventional measure of the pulling (or towing) power of a watercraft, usually a tugboat. Measured in tonnes (TBP).

Quick answer: what is bollard pull?

Bollard pull is the measured static pulling force of a tug or workboat, normally reported in tonnes. It helps compare tug power for towing, escorting, berthing and unberthing jobs.

  • The test is made with the vessel secured and pulling against a fixed bollard or certified load cell.
  • Higher bollard pull does not remove the need to check wind, current, displacement and towline geometry.
  • Use certified TBP figures for planning rather than engine horsepower alone.
