This work examines alternative bulbous bow designs, aiming an advantageous deformation behavior in case of a collision. Thus penetration shall be blunted and critical collision energy level shall significantly be increased. This effect was examined with a test rig especially erected for collision tests with bulbous bows to be driven against ship side structures in a model scale of about 1:3. Examination of the true scale situation was carried out subsequently by using simulations that have been validated with the experimental data. Dimensioning of Bulbous bows with intentionally deformation capability was also carried out with respect to operational loads.
