HEAD SEAS SLAMMING TESTS ON A FAST SURFACE SHIP HULL FORM SERIES

This paper describes recent head seas slamming tests on four models of the NRC hull form series for fast surface ships. This series has been developed using the Canadian DDE-205 frigate as the 'parent' hull form and is defined by systematic variation of non- dimensional geometric parameters involving ship length, beam, draft, block coefficient, and water plane area coefficient. The series provides a database for preliminary design of high speed ships, and for validation of theoretical hydrodynamic models. The series covers, but is not limited to, contemporary frigate and destroyer hull forms. The test variables include model speed, wave frequency and wave steepness. Most tests were performed in regular waves, but a limited number of irregular wave tests were also performed. Test procedures are reviewed, and an overview of results is presented, including bending moment spectra, impact forces and rise times, impact pressures and rise times, and a comparison of theoretical and calculated form factors.
