The Dynamic position vessel
The Dynamic position vessel have a computer controlled system to automatically maintain position and heading by using its own propellers and thrusters. Position reference sensors, combined with wind sensors, motion sensors and gyro compasses, provide information to the computer pertaining to the vessel’s position and the magnitude and direction of environmental forces affecting its position.
The computer program contains a mathematical model of the vessel that includes information pertaining to the wind and current drag of the vessel and the location of the thrusters. The information obtained by the Dynamic Position Vessel allows the computer to calculate the required steering angle and thruster output for each thruster. This allows operations at sea where mooring or anchoring is not feasible due to deep water, congestion on the sea bottom or other problems.
Examples of vessel types that employ DP include, but are not limited to, ships and semi-submersible Mobile Offshore Drilling Units (MODU) and Oceanographic Research Vessels.
