3.5.1 3 DOF Horizontal Motion<br />
The horizontal motion <strong>of</strong> a ship or<br />
semi-submersible is described by<br />
the motion components in surge,<br />
sway, and yaw.<br />
u, v, r n,e, <br />
This implies that the dynamics<br />
associated with the motion in heave,<br />
roll, and pitch are neglected, that is<br />
w=p=q=0.<br />
Low-speed applications-i.e., dynamically positioned ships where U≈0,<br />
and maneuvering at high speed will now be treated separately.<br />
