The K-Pos DP-31 and DP-32 are triple-redundant DP control systems comprising a triple-redundant dynamic positioning system controller unit and three identical operator stations. The controller unit and the operator stations communicate via a dual high-speed data network. Both systems satisfy the requirements of IMO Equipment Class 2 and corresponding class notations.
The DP31 provides a direct interface to the propellers, thrusters and rudders, and includes the necessary interfaces to power plants, position-reference systems and sensors.
The DP-32 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.
Purpose of voting
Detect local interface errors in each controller
Detect sensor errors such as compass drift and sensor breakdown
Ensure that all three computers use the same data as a basis for calculations of command signals and that the command signals are equal from the computers
