Abstract

A purpose-built device was designed to obtain high-quality experimental fluid dynamics (EFD) data of ship roll decay motions initially. Then, a model experiment was conducted for a slender ship using the proposed device with an accurate optical fibre gyroscope. A few important remarks on EFD were derived through analyses of the measured data. Furthermore, unsteady Reynolds-averaged Navier–Stokes computational fluid dynamics (CFD) simulations of the ship roll decay were performed and compared with the results of EFD. Based on the comparisons, a few remarks on the requirements for CFD were derived, those should be considered in the development of guidelines annexed to the Second-Generation Intact Stability Criteria (SGISC) discussed at International Maritime Organization. •A purpose-built device was designed to obtain high-quality EFD data of ship roll decay.•A few important remarks on EFD procedure and EFD analysis of ship roll decay were derived.•Unsteady RaNS CFD simulations of ship roll decay were performed and compared with EFD results.•A few important remarks on requirements for CFD simulation of ship roll decay were derived.
