MEASURED SEAKEEPING ON AN AUSTRALIAN OFFSHORE PATROL BOAT

Motions of a patrol boat in directional sea and swells are described using interim results of instrumented sea trials in August 1992 on 230t patrol boat HMAS WARNAMBOOL in Bass Strait, Victoria, Australia. The trial data shows the effects of combined sea and sell on motion levels and frequency spectra of small ships in realistic confused seas. A new technique for analysing wavebuoy signal spectra successfully separated the individual wind sea and sell spectra, while aerial photography identified their directions and frequencies. Measured results are compared with theoretical predictions. Aspects of theory needing development for accurate data analysis are discussed.
