Strainlabs has initiated a pilot project on the Öresund Bridge, introducing a digital solution to monitor particle magnets installed along the railway track. The magnets prevent iron dust buildup caused by trains, helping avoid operational disruptions. This pilot aims to reduce physical inspections through real-time monitoring of bolted joints using Strainlabs Bolts.
Øresundsbro Konsortiet, which manages the bridge, has long focused on digitalizing its maintenance operations. The bridge already utilizes a digital twin for its 16-kilometer connection, capturing real-time data to enable predictive maintenance.
“We aim for the most data-driven and smart maintenance possible. This pilot is an exciting step toward more AI and machine learning-driven routines. The bridge is designed to last 200 years, and we want to ensure that we are already looking ahead,”
Andreas Jälmarstål, technical manager at Øresundsbron, explained.
The pilot will focus on monitoring the particle magnets that prevent iron dust from interfering with track operations. Without this system, physical inspections are resource-intensive, and loosening bolts can cause severe operational issues. Strainlabs’ solution not only tracks the condition of the magnets but also analyzes how preload changes over time, enabling proactive maintenance.
“This collaboration with Øresundsbron is a significant move from theory to practice. Their forward-thinking approach and openness to innovation make this pilot an exciting first step.”
commented Csaba Madru, CEO of Strainlabs
By automating the monitoring process, the project allows for better maintenance planning, preventing disruptions, and offering a more efficient and safer maintenance approach. The pilot will also help explore other potential applications, such as monitoring large structures and bridge bearings exposed to environmental stresses.
With the project underway, both companies are looking forward to assessing the reliability of the data and scaling up the technology for future maintenance needs on the bridge and beyond.
