Abstract:

The highest loads on bottoms of fast craft are due to slamming, or hydrodynamic impact. A 9 meter long steelcomposite hybrid slamming load test facility has been employed for the purpose of furthering understanding of the slamming phenomenon. This craft is heavily instrumented with strain gages, accelerometers, cameras, an inertial navigation system and more. It has been subjected to tests in a lab environment, in calm seas, and in rough seas. Slamming tests were performed in the Atlantic Ocean at places such as off the coast of Barnegat Light, NJ. During these tests the boat was operated in sea state 3 at speeds of roughly 25 ms. The data collected have been used to compare the behavior of the different bottom panels of the hull. In particular the response of starboard and port panels with different structural properties were compared, using time response, frequency spectra, peak counting, etc.
