Abstract
The first results obtained using two seakeeping computation codes developed at Ecole Centrale de Nantes (Aquaplus) and at the LEA-Poitiers (Poseidon) are presented. Both use the diffraction-radiation with forward speed Green function, but with two different formulations, in a panel code in the frequ ency domain. Results obtained with both codes are in good agreement and als o retrieve test measurements or other calculations available. However irreg ular frequencies and their links with the waterline integral are made evide nt. (C) 2001 Academie des sciences/Editions scientifiques et medicales Else vier SAS.
