Dual Redundant Dynamic Positioning system, K-Pos D
The K-Pos DP-21/22 dynamic positioning - DP system consists of a dual DP controller unit and operator stations. The controller unit and the operator station communicate via a dual high-speed data network.
K-Pos DP-21 dynamic positioning system
The DP-21 provides a direct interface to the propellers, thrusters and rudders, and includes the necessary interfaces to power plants, position-reference systems and sensors.
K-Pos DP-22 dynamic positioning system
The DP-22 is designed for integration with K-Chief (marine automation system) and K-Thrust (thruster control system) via a dual Ethernet LAN. Dual redundancy is also built into the interface units for connection of sensors and position reference systems.
Integrating all the functions for monitoring and control of a vessel provides a real benefit both technically and economically. Functions are integrated to reduce the overall need for hardware and software functions and to reduce interfacing requirements. This leads to less demand for special software, cabling and testing. Furthermore, integrated systems offer a far greater degree of redundancy, and therefore increased system availability and operational performance.
Dual redundancy advantages
No single point failure. The system is designed to avoid total system failure if a single failure occurs.
If one system component fails, the other components will not be affected.
Detection of failure
The working part of the dynamic positioning system will detect a failure, allowing corrective actions to be taken.
Switch-over to hot standby
If the on-line computer in the system fails, a successful switch-over to the hot standby computer occurs automatically.
DP class notation
The K-Pos DP-21 and 22 dynamic positioning systems meet the Equipment Class notation for Class 2 DP systems. The flexible nature of K-Pos systems allow them to be upgraded to Equipment Class 3 if/when required.

Dynamic positioning operator interface
The operator interface is designed to allow efficient and safe operation of the dynamic positioning system by assisting the operator in making optimum operational decisions.
