Dynamic Positioning

Dynamic Positioning is a method to keep a ship, platform or subsea vehicle stationary over a fixed spot on the seafloor. Such station keeping is desirable for many tasks including coring, drilling, lifting, sampling, and diver support. DP systems use thrusters in the bow and stern to maintain position. A computer is used to direct power to each thruster when necessary based upon input from GPS, compass, motion sensors, wind sensors, current meters, acoustic navigation equipment and other systems.
