3D sonar sensors are bringing a vision of automated navigation for inland shipping closer to realisation.
A project by UAntwerp (University of Antwerp) and the Port of Antwerp has seen the development of a 3D sonar sensor with 32 sophisticated waterproof microphones. The project is called eRTIS, which stands for 'embedded Real Time Imaging Sonar'.
Prof. Jan Steckel at CoSys-Lab, a research group in UAntwerp's Faculty of Applied Engineering, explained: “The information is transmitted in real time, because if there are any delays, the ship could crash into something. The 'Imaging Sonar' part refers to reflected sound waves hitting the sensors to create a picture of the surroundings.”
Test vessel success
In the last weeks of 2020, the technology was successfully tested on the Tuimelaar, one of the Port of Antwerp's test vessels. In 2021, there will be a follow-up project: as part of the Smart Docking Innovation Challenge, the Port of Antwerp has given the green light to Prof. Jan Steckel's 3D Sonar and Lidar for Vessel Monitoring project.
Prof. Jan Steckel develops advanced sensor systems that can withstand harsh conditions. He said that sonar sensors remain fully functional in poor visibility due to dust, water sprays, mud, smoke or fog, unlike cameras. Sonar sensors can provide a reliable picture of the ship's surroundings at a low cost.
“In 2019, over 42% of all goods entered or left the port of Antwerp via inland waterways,” said port alderman Annick De Ridder. “In other words, inland shipping is crucial if we want to ensure the accessibility of our city and our port. By focusing on technology such as unmanned navigation, we want to further increase both the market share and the competitiveness of inland shipping.”
Svetlana Samsonova, coordinator of the partnership between UAntwerpen and Port of Antwerp, stressed that unmanned vessels can help save costs, reduce traffic congestion and provide a solution to the rising costs of road transport.
