• Low Frequency Excitation and Damping of Four MODUs in Severe Seastates With Current 

      Fonseca, Nuno; Stansberg, Carl Trygve; Larsen, Kjell; Bjørkli, Rune; Vigesdal, Tjerand; Dalane, Oddgeir (ASME digital collection;OMAE2018-77873, Chapter, 2018-06-26)
      Model tests have been performed with four mobile offshore drilling units (MODUs) with the aim of identifying wave drift forces and low frequency damping. The MODUs configuration is different, namely on the number and ...
    • Wave-Current Interaction Effects on Airgap Calculations 

      Hermundstad, Elin Marita; Hoff, Jan Roger; Fonseca, Nuno; Bjørkli, Rune (ASME Proceedings | Offshore Technology;OMAE2017-62548, Chapter, 2017-06-25)
      The importance of wave-current interaction effects on the determination of mean drift forces on floating offshore structures is well documented. Wave-current interaction effects will also influence the first-order motions ...
