Scope
A ship can be considered to have six degrees of freedom in its motion, i.e., it can move in any of six axes.
Three of these involve translation:
- surge (forward/astern)
- sway (starboard/port)
- heave (up/down)
and the other three rotation:
- pitch (rotation about surge axis)
- roll (rotation about sway axis)
- yaw (rotation about heave axis)
Dynamic positioning is concerned primarily with control of the ship in the horizontal plane, i.e., the three axis surge, sway and yaw.
