• Comparison study of umbilicals' curvature based on full scale tests and numerical models 

      Dai, Tianjiao; Sævik, Svein; Ye, Naiquan (Journal article; Peer reviewed, 2016)
      A full scale test was carried out for a dynamic steel tube umbilical under combination of tensile and bending loads. The purpose of the test was to investigate the behavior of the dynamic bending under complex loading ...
    • Design Study of a Hybrid Power System for a Ferry Using Open Simulation Platform 

      Yum, Kevin Koosup; Ludvigsen, Kristine Bruun (Peer reviewed; Journal article, 2021)
      In a hybrid power system, an energy storage device unlocks the possibility of optimizing the design and operation. Only a properly tuned control strategy with correctly sized machinery under specific operation profiles ...
    • Dynamic response of a top-tensioned riser under vessel motion 

      Yin, Decao; Passano, Elisabeth; Lie, Halvor; Grytøyr, Guttorm; Aronsen, Kristoffer; Tognarelli, Michael; Kebadze, Elizbar Buba (Journal article; Peer reviewed, 2018-07)
      Model tests of a top-tensioned riser model were carried out as a part of a joint industry project, with the purpose of verifying the calculations of the riser analysis program RIFLEX. Sinusoidal motion in one direction was ...
    • Intercomparison of Wave Reanalysis based on ERA5 and WW3 Databases 

      Stefanakos, Christos (Journal article; Peer reviewed, 2019-06)
      In this work an intercomparison of two wave reanalysis products, namely ERA5 and CFSR-W (WW3 hereafter), is presented. The datasets are assessed by means of several statistical features, such as seasonal variability, ...
    • Nonstationary prediction of wind and waves in the pacific ocean using fuzzy inference systems 

      Stefanakos, Christos (Journal article; Peer reviewed, 2016-06)
      In the present paper, ten-year long three-hourly time series of wind and wave data, based on hindcasts of WAVEWATCH III model, are analyzed and modelled as nonstationary stochastic processes. The study area covers the ...
