A new implementation of strip theory is proposed based on the strip theory by Salvesen, et al. [1] and early work by Westlake and Wilson [2]. Compared with traditional strip theory, the main difference is that the calculation is carried out in the time domain. This makes it possible to cope with relatively large-amplitude motions and non-constant forward speed problems.
At each time step, the exact underwater sections are extracted; the velocity potential is required to satisfythis instantaneous body boundary condition, therefore the added mass, damping coefficients and exciting forces are timevariant, which produce a non-linearity. The diffraction force is added to work ofWestlake and Wilson, and the results show the effect of diffraction force is significant.
