Seeing above the waves: A modular sensing framework for data acquisition at sea
Jonathan E. Schmidt, Julius Wirbel, P. Nicholas Hansen +4
Advancing autonomy for surface vessels requires systematic evaluation of their sensing and perception subsystems. Yet, maritime environments impose unique challenges: sensor instal…
Exploring LLM Capabilities for Situational Understanding and COLREG compliance on real-world maritime navigation scenarios
Julius Wirbel, P. Nicholas Hansen, Line K. H. Clemmensen +1
Recently, Large Language Models (LLMs) have shown considerable capability for situational understanding, reasoning, and decision making in different domains, most notable in the au…
Seabed-to-Sky Mapping of Maritime Environments with a Dual Orthogonal SONAR and LiDAR Sensor Suite
Christian Westerdahl, Jonas Poulsen, Daniel Holmelund +3
Critical maritime infrastructure increasingly demands situational awareness both above and below the surface, yet existing ''seabed-to-sky'' mapping pipelines either rely on GNSS (…
Codification of Good Seamanship in Complex and Congested Waterways
Yaqub Aris Prabowo, Peter Nicholas Hansen, Dimitrios Papageorgiou +1
This paper presents a novel method to quantify seafarers' good seamanship during navigation scenarios with multi-vessel encounters -- in open and confined waters --, and to compute…
Stochastic COLREGs Evaluation for Safe Navigation under Uncertainty
Peter Nicholas Hansen, Dimitrios Papageorgiou, Roberto Galeazzi +1
The encounter situation between marine vessels determines how they should navigate to obey COLREGs, but time-varying and stochastic uncertainty in estimation of angles of encounter…
Autonomous Navigation in Confined Waters -- A COLREGs Rule 9 Compliant Framework
Peter Nicholas Hansen, Thomas T. Enevoldsen, Dimitrios Papageorgiou +1
Fully or partial autonomous marine vessels are actively being developed by many industry actors. In many cases, the autonomous vessels will be operating close to shore, and within…
