The purpose of Model Seakeeping Experiments Presented in the Time-Domain to Facilitate Validation of Computational Tools has been to put together a well-arranged bank of model measurements, useful as a reference material in the validation procedure of real-time simulation models.

The work reports on seakeeping experiments on a model of an 11300 tonne ro-ro vessel. All information is at hand: hull geometry, model condition, test set-up, procedures and time series of the measured quantities.

The time series, together with the hull geometry, is stored on CD-ROM. The printed part of the work reports on the test set-up, procedures and post-processing, and gives a catalogue with overall data on each test. Experiments were performed in regular, irregular and short-crested waves at two speeds, corresponding to five and 15 knots, with relative heading varied around the clock. The wave systems were modelled by regular waves with amplitude corresponding to one-three metre and of irregular waves with significant wave height of five metre. For each test, the waves are described by an analytical expression. Those wave equations describing the wave elevation in time and space, can be used as sea environment when comparing the measurements with time-domain simulations.

The recorded data are from measurements of wave elevation, global and local motion, velocity and acceleration. Each of the 110 tests are described by time series recorded from 18 measurement channels.

Thanks to the generality of the tests and the accessibility of hull geometry and time series, the work should be useful not only as reference in cases of validation, but also to illustrate the dynamic behaviour of ships in the education of naval architects.
