The winner of the 'Safe Bollards' challenge is announced

Friday 12 02 2021

In 2020, Port of Antwerp launched a call to devise a digital solution to improve the safety of bollards. The competition winner, Zensor, designed a sensor that detects when bollards are overloaded.

A bollard under too much tension can be a risk. If the bollard and mooring rope come loose, a ship can drift, and the huge tractive force can damage quay walls or tear bollards loose.

 

Bollard Monitor

To prevent this, the Brussels-based technology company Zensor devised the "Bollard Monitor". A sensor on the bollard continuously records and transmits information.  An online alarm signal sounds in the event of overload. The data collected will make preventative maintenance planning more efficient. In early 2021, Port of Antwerp fitted five bollards with sensors, and five additional bollards on the North Sea Terminal will follow shortly.

Bollard or mooring mast? 

The port has about 7000 mooring masts and bollards. But do you know the difference? A mooring mast is made of concrete. A bollard is made of steel and has an anchor or bolt connection, making it more vulnerable to the large tractive force of a seagoing vessel.
