What is Bollard Pull? Everything You Wanted To Know

The Bollard Pull Test of Vessels & Barges, also known as the tractive force of a tug expressed in metric tonnes (T) or KN, is a trial used to assess the static pull or zero-speed tugging that a tug can deploy in working conditions. To estimate the maximum tractive force of the tug engaged in the towing for optimal planning and safe operation, the bollard pull calculation is crucial and one of the most often used tests in marine towing operations.

To reduce any potential outside influences that could alter the test outcome, the Bollard Pull test is often carried out in perfect climatic conditions, or as close to ideal as possible. Because such conditions won’t yield consistent findings, the test is often not carried out in typical operating circumstances such as shallow water, severe seas, high winds, or tight harbor basins.

The static force exerted by a tug at zero speed on a fixed line is known as bollard pull. Almost invariably, a test is attaching a line to a shore-based bollard, which is a brief vertical post, and increasing the engine’s RPMs to full throttle, usually in both ahead and astern situations.
