System overview The KONGSBERG K-Thrust TC concept combines autono- mous control systems for each propulsion and thruster unit into one system for mode selection and command responsi- bility transfer. A Thruster Controller is the main unit of each control system. This cabinet is often located near the propulsion unit or its motor controller. From the Thruster Controller, a communication bus links operator panels on the bridge and in the ECR (where applicable) to the controller. The bus based communication between intelligent components sim- plifies installation and reduces overall cost....

K-Thrust TC general features Command responsibility transfer between bridge positions and between bridge and engine room is handled by synchro- nisation of the individual thruster controllers. Command transfer within the bridge is common to all units, while transfer to/from the ECR can be individual to each unit. Bumpless transfer between locations is either by manual alignment of the thruster levers following the guidance given on the panel, or automatically by the "electric shaft" Command responsibility transfer between control systems is handled from mode selection panels that...

The Thruster Controller unit contains the control system processor(s). It interfaces the operator panel communication bus and serves as field interface to the servo actuators, servo controllers (applies to pitch and azimuth control), feedback units Thruster Controllers receive commands from other control systems (e.g. DP controller) via a local area network or by direct wiring. Commands from the operator are read via the panel bus. Both the local area network and the panel bus are installed in a star topology ensuring that a single malfunction in communication does not affect more than a...
