How Dynamic Positioning System works ?

We are not going into technical jargon but in simple terms the Dynamic Positioning Systems consists mainly of 3 systems

1. DYNAMIC POSITIONING REFERENCE SYSTEMS
As the name suggests these system are used for reference of the vessel e.g. Position reference, heading reference, motion reference, magnitude and direction of environmental forces (wind, current etc.), depth and other reference depending on the DP Class and DP Vessel's Operation.


2. DYNAMIC POSITIONING CONTROL SYSTEMS
These are controllers and they use mathematical model of the ship, based on a hydrodynamic and aerodynamic description of DP Vessel characteristics. These use the data from the Reference system, does its own complex calculations as per the required DP Operation and controls the Power and Propulsion System of the DP Vessel.


3. DYNAMIC POSITIONING POWER AND PROPULSION SYSTEMS
Power units and the Propulsion unit of the Dynamic Positioning System consists of the Bow and stern thrusters, water jets, rudders and propellers. These control the Positioning or heading or even precision maneuvering of the DP Vessel. Most of the commands are controlled by the Control Systems. On DP Class 1 vessel the setup is simple but DP Class 2 and 3 DP ships, all computers and reference systems should be powered through a UPS.
