    • Estimating waves via measured ship responses 

      Nielsen, Ulrik Dam; Bingham, Harry B.; Brodtkorb, Astrid H.; Iseki, Toshio; Jensen, Jørgen Juncher; Mittendorf, Malte; Mounet, Raphaël Emile Gilbert; Shao, Yanlin; Storhaug, Gaute; Sørensen, Asgeir Johan; Takami, Tomoki (Peer reviewed; Journal article, 2023)
      Optimisation of energy efficiency and operational performance as well as assessment of safety levels and emissions of marine operations require detailed information about the acting wave system. It is possible—with an ...

    • Estimation of autocorrelation function and spectrum density of wave-induced responses using prolate spheroidal wave functions 

      Takami, Tomoki; Nielsen, Ulrik Dam; Jensen, Jørgen Juncher (Peer reviewed; Journal article, 2021)
      Predicting the wave-induced response in the near-future is of importance to ensure safety of ships. To achieve this target, a possible method for deterministic and conditional prediction of future responses utilizing ...

    • Estimation of Extreme Roll Motion Using the First Order Reliability Method 

      choi, ju-hyuck; Jensen, Jørgen Juncher; Nielsen, Ulrik Dam (Chapter, 2021)
      Extreme value statistics can often be based on the assumption that exceedance events of a high threshold level are statistically independent and identically distributed (i.i.d. process), which further implies the Poisson ...

    • Real-time deterministic prediction of wave-induced ship responses based on short-time measurements 

      Takami, Tomoki; Nielsen, Ulrik Dam; Jensen, Jørgen Juncher (Peer reviewed; Journal article, 2021)
      This paper studies real-time deterministic prediction of wave-induced ship motions using the autocorrelation functions (ACFs) from short-time measurements, namely the instantaneous ACFs. The Prolate Spheroidal Wave Functions ...

    • Reducing uncertainty of Monte Carlo estimated fatigue damage in offshore wind turbines using FORM 

      Horn, Jan-Tore H.; Jensen, Jørgen Juncher (Chapter, 2016)
      Uncertainties related to fatigue damage estimation of non-linear systems are highly dependent on the tail behaviour and extreme values of the stress range distribution. By using a combination of the First Order Reliability ...

    • Response predictions using the observed autocorrelation function 

      Nielsen, Ulrik Dam; Brodtkorb, Astrid H.; Jensen, Jørgen Juncher (Journal article; Peer reviewed, 2018)
      This article studies a procedure that facilitates short-time, deterministic predictions of the waveinduced motion of a marine vessel, where it is understood that the future motion of the vessel is calculated ahead of time. ...
