On January 24, 2024, the kick-off workshop for the initiation of work package 3 was conducted at the University of Leiden. The workshop featured presentations by key contributors, including Arnold Tukker, the leader of work package 3, PhD candidates Faysal Tareq and Laura Bremenkamp, Bouwen met Staal (BmS), Madaster, and the Municipality of Amsterdam. The session concluded with a comprehensive discussion among the participants.
A crucial point of focus during the workshop was the discussion on the scope of the activities undertaken by the two respective PhD candidates. This led to an engaging dialogue on the scale of their endeavors, considering local, national, EU-wide, or global perspectives. Within this context, the role of case studies was jointly examined. Particularly challenging will be the positioning of Laura’s efforts within the jurisdiction of policy and governance for major steel infrastructures. However, insights from industrial partners present at the workshop shed light on what is pertinent in the Dutch steel infrastructure landscape. These partners also shared information on the broader economic structures related to supply and demand within the Dutch steel sector.
For Laura, an additional consideration is the specification of the exact types of steel networks to be analyzed, making the specific scope clearer and the task more manageable. Industry partners extended their assistance to both PhD candidates.
The Municipality of Amsterdam delivered an insightful presentation on potential candidates for case studies in the project. Recognizing the importance of case study selection, especially for Laura, it was collectively agreed that the next step would involve relevant industry partners (Province of South Holland, North Sea Port, Municipality of Amsterdam, and Rijkswaterstaat) providing their top 3 candidates. This approach allows Laura to proceed with scanning and advancing her data collection efforts, aimed at mapping the relational networks influencing the Dutch steel landscape.
"I found great delight in participating in this workshop. It provided valuable insights from both industry and academic partners, shedding light on the contents and scope of work package three. I particularly appreciated the advancements made in the selection of the case study, a crucial step for the further progression of my research".
CT de Boer Showcases SUBLIME Fieldwork at the 2025 M2i Conference
During the 2025 M2i Conference at Papendal, Anton Gorter of Civiele Technieken de Boer presented the progress of SUBLIME’s field monitoring work on the Van Hall Bridge in Amsterdam. His talk, “An on-site measurement campaign – it sounds so simple” highlighted the many practical steps and unforeseen challenges involved in collecting high-quality strain data on a historic movable steel bridge.
Sheet Pile Corrosion Study Begins
The SUBLIME project is taking a major step forward in understanding how steel sheet piles age in real port conditions. In close collaboration with North Sea Port (NSP), TU Delft researcher Prasaanth Ravi Anusuyadevi is preparing the installation of a new field-testing structure that will allow long-term monitoring of corrosion processes on S355 steel.
Following recent discussions between TU Delft and NSP, both partners agreed to install a dedicated sample-carrying structure directly in the port. The design includes three identical frames, each hosting nine steel samples and each intended for different exposure durations: 3 months, 6 months and 1 year. The samples will be positioned at different depths along the waterline to capture how corrosion varies from splash zone to full immersion.
Smarter Cameras from Fewer Views — A Sparse-View Pose Estimation
How do you recreate a 3D scene using just a few pictures from different angles? That’s a challenge many fields face — from drone-based inspections to 3D mapping for remote sensing or structural health monitoring. Qingyu Xian, PhD researcher at the University of Twente, is tackling this challenge head-on in the SUBLIME project with a novel tool that’s already showing strong results: the T-Graph module.
Smarter Testing for Steel Bridges: How Few Tests Can Tell Us More
Many steel bridges across Europe are reaching the end of their intended service lives, raising critical questions about how to assess and extend their safe use. Within the SUBLIME program (“Sustainable and Reliable Macro Steel Infrastructures”), our mission is to ensure that these critical structures remain safe, sustainable, and serviceable for decades to come. One of the program’s key objectives is developing smarter assessment tools that help us better understand the condition of ageing steel — particularly when data is limited. That’s where the work of Elena Zancato, PhD researcher at Eindhoven University of Technology (TU/e), comes into focus.
WP3 Progress Meeting and Workshop on Sustainable and Reliable Steel Infrastructure
On 11 September 2025, the SUBLIME consortium convened at Leiden University for the WP3 progress meeting and workshop on sustainable and reliable steel infrastructure. Presentations by PhD researcher Faysal Tareq (Leiden University, CML) and Mic Barendsz (Bouwen met Staal) addressed material flows, carbon emissions, and circular design strategies. In the afternoon, Dr. Mohammad Hamida (TU Delft) led an interactive workshop exploring technical, environmental, economic, legal, and social challenges, and identifying possible solutions. The event highlighted the importance of combining material analysis, design practice, and governance perspectives to guide the transition toward circular and climate-resilient steel infrastructures.
Ali Sabzi to Present SUBLIME Research at IEEE SmartNets 2025 in Istanbul
On March 21, 2025, the SUBLIME project consortium gathered for its 2nd Annual User Committee Meeting. Hosted by North Sea Port (NSP) at its Vlissingen premises, the meeting brought together over 30 representatives from research institutions, industry partners, government bodies, and funding agencies to reflect on progress, share research outcomes and explore pathways for future collaboration.
The day featured presentations from PhD and EngD researchers, discussions on key user cases and a site-specific boat tour through the North Sea Port, highlighting the real-world relevance of the project’s themes—fatigue, corrosion, digital monitoring and infrastructure sustainability.
