      Modern design for marine and coastal activities places increasing focus on numerical simulations. Several numerical wave models have been developed in the past few decades with various techniques and assumptions. Those ...

    • Effect of modelling inhomogeneous wave conditions on structural responses of a very long floating bridge 

      Dai, Jian; Stefanakos, Christos; Leira, Bernt Johan; Alsos, Hagbart Skage (Peer reviewed; Journal article, 2021)
      Floating bridges are suitable for connecting land parcels separated by wide and deep waterbodies. However, when the span of the crossing becomes very long, the water environment exhibits inhomogeneities which introduce ...

    • Experimental and Numerical Study of Pre-Swirl Stators PSS 

      Koushan, Kourosh; Krasilnikov, Vladimir; Nataletti, Marco; Sileo, Lucia; Spence, Silas John Byron (Journal article; Peer reviewed, 2020-01-16)
      Energy saving within shipping is gaining more attention due to environmental awareness, financial incentives, and, most importantly, new regional and international rules, which limit the acceptable emission from the ships ...

    • Fatigue Analysis of Inter-Array Power Cables between Two Floating Offshore Wind Turbines Including a Simplified Method to Estimate Stress Factors 

      Beier, Dennis; Schnepf, Anja; Van Steel, Sean; Ye, Naiquan; Ong, Muk Chen (Journal article; Peer reviewed, 2023)
      The use of floating offshore wind farms for electrical energy supply is expected to rise significantly over the coming years. Suspended inter-array power cables are a new design to connect floating offshore wind turbines ...

    • Free Surface Reconstruction for Phase Accurate Irregular Wave Generation 

      Aggarwal, Ankit; Pakozdi, Csaba; Bihs, Hans; Myrhaug, Dag; Alagan Chella, Mayilvahanan (Journal article; Peer reviewed, 2018-09-29)
      The experimental wave paddle signal is unknown to the numerical modellers in many cases. This makes it quite challenging to numerically reproduce the time history of free surface elevation for irregular waves. In the present ...

    • Global wind and wave climate based on two reanalysis databases: ECMWF ERA5 and NCEP CFSR 

      Stefanakos, Christos (Peer reviewed; Journal article, 2021)
      In the present work, the global wind and wave climate is studied on the basis of two well-known reanalysis products, namely ERA5 and CFSR-W (WW3 hereafter). Several statistical features of the datasets are assessed, such ...

    • Modelling of Synthetic Fibre Rope Mooring for Floating Offshore Wind Turbines 

      Sørum, Stian Høegh; Fonseca, Nuno; Kent, Michael; Faria, Rui Pedro (Journal article; Peer reviewed, 2023)
      Fibre ropes offer beneficial properties for mooring of floating offshore wind turbines (FOWTs). However, the mooring line’s stiffness is both load-history and load-rate dependent. A quasi-static stiffness is observed for ...
