Tugboat towing a large container ship on sea.
What is a Bollard Pull Test?
A Bollard Pull Test is the standard method used to determine the maximum pulling force a tugboat or marine vessel can produce. During the test, the vessel is securely connected to a fixed bollard onshore through a calibrated load cell, which accurately measures the pulling force generated by the vessel.
This test is widely used for:
- Tugboat performance verification
- Marine vessel acceptance testing
- Shipyard inspections
- Offshore vessel commissioning
- Regulatory compliance
- Equipment performance validation
Without an accurate force measurement system, the results cannot be trusted, leading to failed certifications, repeated testing, and increased operational costs.
How a Load Cell Works in Bollard Pull Testing
The load cell is the heart of every bollard pull test. It converts the mechanical pulling force generated by the vessel into an accurate electrical signal that can be recorded, analyzed, and reported.
Typical Testing Process
- The tugboat is connected to a fixed bollard using a towing line.
- The load cell is installed between the bollard and the towing line.
- The vessel gradually increases engine power.
- The load cell continuously measures the pulling force.
- Data is transmitted to a display or data logger.
- Engineers analyze the recorded force to verify vessel performance.
The accuracy of this process depends entirely on the quality and calibration of the load cell.
