A Fully Nonlinear, Dynamically Consistent Numerical Model for Ship Maneuvering in a Seaway

Figure 1

The numerical driving and restoring forces (moments) for heave (a), pitch (b), and roll (c) from the original DiSSEL. The ship hull is EHF, with a rudder angle 𝛿=15^∘ and the Froude number 𝐹_𝑟=0.266. The incident wave height is 𝑤ℎ=1.496 m, and its wavelength normalized by ship length is 𝜆=1.0 (Case 1). The superscripts “𝑝” and “𝑞” represent the driving forces (moments) and restore forces (moments) which associated with (4c), (4d), and (5c), and (5d).
