Marex OS VBR for Voith-Schneider propellers

Content
Schulpengat VSPTexel
 

Passenger ships and work boats navigate safely with this control. Developed in close cooperation with Voith Turbo, the Marex OS VBR is perfectly suitable for Voith-Schneider propellers, controllable pitch and rudder propellers, new or retrofit.


Advantages

  • System availability at all times ensures extreme safety in operation: A redundancy concept covers all functions from the control stations' electronics to the hydraulic cylinders and actuator shaft.
  • Economic efficiency: Resource-economizing navigation profiles can be defined to save fuel.
  • Durability: All components of the drive chain are attuned to each other which reduces the wear of material.
  • Certified quality: On request, the system is type-approved by Germanischer Lloyd, Bureau Veritas, Det Norske Veritas, American Bureau of Shipping, Rina, LLoyd's Register.


Technology

The control converts the operator's control commands into CAN-bus signals. Redundant systems are provided with an additional potentiometer. The commands which are entered by means of the keys and the feedback to the lamps are transmitted intelligently to both systems. The signals are processed according to the time and pitch curves in store and transmitted to automatic proportional valves or actuators. Alternatively, the signals can be transmitted to the PLC which will then actuate the shaft adjustment.


Features

  • 2-chain-control with the option of "hot"redundancy
  • Control of up to 10 parallel propulsion chains or 5 redundant propulsion chains
  • Operation of up to 6 control stations
  • Engine interface including clutch control (combustion or electric engines)
  • Interfaces to auto pilot and DP-systems (DP0 to DP3)
  • Standard module for I/O extension
  • Interface for roll stabilization with VSP
  • Extended functions realized by integrated PLC
  • Up to 6 different navigation profiles (combinator, constant speed) can be realized.
  • Electro-mechanical control of the VSP with integrated hydraulics
  • Electro-hydraulic control of VSP (EC type)
  • Extention by a PLC-based controller for the shaft control

The components

  • At the control stations: joysticks, Azimut controllers or control heads with steering wheel corresponding to the number of drives to be controlled, providing redundancy on request.
  • At the VSP drive: control cabinet with system controller (redundancy on request)
