      Autonomous underwater vehicles (AUVs) are efficient sensor-carrying platforms for mapping and monitoring undersea ice. However, under-ice operations impose demanding requirements to the system, as it must deal with uncertain ...
    • Bayesian Estimation of Non-Stationary Ship Response Spectra 

      Møgster, Christian (Master thesis, 2015)
      The main topic of this master thesis is to obtain spectral information of non-stationary ship responses, with the motive of facilitating improvement of sea state estimation methods, that are using the wave buoy analogy. ...
    • A Bayesian network risk model for predicting ship besetting in ice during convoy operations along the Northern Sea Route 

      Xu, Sheng; Kim, Ekaterina; Haugen, Stein; Zhang, Mingyang (Journal article; Peer reviewed, 2022)
      To facilitate shipping in ice and to meet the increasing requirements of icebreaker services, convoy operations are the most effective alternative. However, convoy operations are among the most dangerous operations as they ...
    • A benchmarking exercise for environmental contours
