The newly launched Bollard Load Test system is a fully calibrated, easy to use solution to safely test the strength of marine mooring bollards.
Bollards come in many shapes, sizes, capacities and materials and throughout their life will suffer corrosion, fatigue and other effects.
The forces exerted on a bollard are considerable, in excess of 2000kN, which can weaken the bollard and its fixings to the point that the bollard fails to withstand such forces. Should this happen, it can cause damage to dockside equipment and the quayside, as well as serious or fatal accidents. It is therefore prudent to test dockside bollards at regular intervals.
The BLT system (patent pending) replaces the traditional method of a tug pulling against the bollard, a method that has previously caused damage to vessels and can be dangerous to the people involved in the test.
The breakthrough technology uses a powerful hydraulic cylinder and custom designed dyneema to recreate conditions that are equivalent to 120 metric tonnes of ‘pull’.
The system allows for standardised testing of bollards by replicating the various forces and movements which they may experience when used to moor a vessel. The strength of the bollard is measured using a pressure transducer fitted to the hydraulic cylinder to relay pressure back to a digital gauge in a remote location. The BLT can simulate spring lines at various angles up to 20 degrees thus giving a great deal of confidence in the bollard and surrounding structures.
BLT: how safe are your bollards?
An often overlooked area when it comes to the safe mooring of vessels in ports, shipyards and harbours is testing the safe working load (SWL) of bollards. With the size of vessels ever-increasing, the time has come to focus and raise the issues that have been experienced with bollard failure, as well as the challenges faced in testing the SWL of bollards.
