Port installs smart bollards with sensors

03 Feb 2021 / Antwerp, Belgium

Port of Antwerp and technology company Zensor are joining forces to increase safety at the quay walls. Zensor developed the Bollard Monitor, a digital sensor that measures the tension on a bollard. The first five Bollard Monitors have been installed at the North Sea Terminal, and five more are planned shortly.

The port of Antwerp has some 120.6km of quay walls and 7,000 mooring posts and bollards. This is where ships attach their ropes when mooring up. This way, ships do not move about during loading and unloading. In windy or stormy conditions, the ropes of large seagoing vessels exert an enormous tractive force on the mooring posts and bollards. Bollards, with their bolt or anchor connections, are more sensitive than mooring masts in this respect. If such a bollard – 650kg of steel – were to come loose, there is a risk that a ship could drift away or that people would be injured. Regular inspection and maintenance are therefore required…

…The Bollard Monitor consists of two built-in sensors, which measure the tension and tension fluctuations on the mounting system. Every 15 minutes, the system sends the information, which is permanently recorded, via a wireless connection and visualises it via a dashboard. This data will help the operational department to optimise the preventative maintenance of the bollards…
