Posters
Come meet the poster presenters to ask them questions and discuss their work
We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics, and will give delegates an opportunity to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in industry and the academic community.
On 9 April at 17:15, we’ll also hold the main poster session and distinguish the 7 best posters of this year’s edition with our traditional Poster Awards Ceremony. Join us at the poster area to cheer and meet the laureates, and enjoy some drinks with all poster presenters!
We look forward to seeing you there!
PO187: Improving EM-based submarine cable tracking: Mitigating the effects of seawater, nearby cables, and infrastructure
Tobias Stolz, Lead Developer, Seekable
Abstract
In offshore wind farms, maintaining the integrity and security of export and inter-array cables is crucial. These cables, buried at typically depths of 1.5 to 3 meters, face risks from fishing activities, anchoring, sabotage, and natural hazards. Accurate monitoring of the Depth of Burial (DoB) is essential for ensuring these critical infrastructure assets' safety and reliability. This presentation explores advanced techniques for cable tracking using the electromagnetic (EM) method. Traditional cable tracking models, assuming a static straight wire in air, often fall short in real-world scenarios, leading to inaccuracies in cable position and depth estimates. This study highlights the limitations of these simple models and introduces enhanced approaches to address them. The research specifically focuses on three key factors affecting accuracy: the conductive medium of seawater, the presence of nearby cables, and magnetic noise from surrounding infrastructure. Through simulated and real data, we demonstrate how seawater's conductive properties cause increased attenuation of the magnetic field, resulting in underestimated cable positions. We also show that nearby cables introduce magnetic field distortions, leading to biased position estimates. Additionally, magnetic noise from infrastructure in congested areas further complicates accurate tracking. Our findings emphasize the importance of updating cable tracking models to account for these environmental and structural factors. Enhanced models that incorporate seawater conductivity, proximity effects, and magnetic noise can significantly improve the accuracy of cable position measurements. This paper aims to restore confidence in EM cable tracking systems by demonstrating the effectiveness of comprehensive modeling techniques in overcoming common tracking challenges.
