... on the repeatability of phase resolved seaways, the spatial variability of wave parameters throughout the basin, and the stationarity of the wavefield over the span of 2 hours. Two different wave spectra were run repeatedly over a two week test window covering 21 discrete locations with one fixed array of sensors...

... an experimental methodology to get the maximum wave impact pressure due to the slamming occurrence on a floating structure. This was demanded in a model test in the wave basin of LabOceano, COPPE/ UFRJ. The pressure instrumentation was based on a sensor’s grid measurement system. This allowed covering a larger...

... Division, a directional wave array was employed using five ultrasonic level sensors in an array to quantify wave direction in the Maneuvering and Seakeeping basin (MASK). Two methods were then used to calculate wave direction, a phase/path/time difference method of Esteva which yields a mean direction...
