Rexroth has adapted and optimised its world-renowned Marex OS remote control for use with Voith-Schneider's ship propulsion systems.
In collaboration with Voith Turbo Marine, Rexroth has adapted and optimised its world-renowned Marex OS remote control for use with Voith-Schneider's ship propulsion systems.
Building on 40 years of experience in the design and development of remote controls for ship propulsion systems, the new and innovative Marex OS for VSP (Voith-Schneider Propellers) and VCR (Voith-Schneider Cycloidal Rudders) systems from Rexroth has opened up a tranche of new possibilities for the UK marine retrofit market.
Due to its modular design, Rexroth's Marex OS remote control can be adapted easily to almost any type of ship and propulsion system.
The CANbus serial network design provides the "Open System" backbone of this product from Rexroth, offering excellent security as well as the ultimate flexibility in installation, programming and adjustment of marine controls.
What's more, reliability of operation is ensured by a redundant bus layout and redundant hardware design.
Of particular interest to UK boat builders and shipyards is that existing Voith-Schneider propulsion systems can be retrofitted with Rexroth's Marex OS control system.
As a result, the incumbent propulsion system, which is often heavy and complex in nature as well as being inflexible, can be installed and commissioned cost-effectively with a prefabricated modular system.
What's more interesting is that during the retrofit additional control auxiliaries can be integrated to upgrade and enhance the vessel's handling capability.
Once connected to a GPS system for instance, dynamic positioning is viable.
Dynamic positioning control maintains a ship's position and heading automatically, enabling operations at sea where mooring or anchoring is not feasible - a safety tug monitoring an oil rig or offshore wind farm is a typical example.
Roll stabilisation, overload control and autopilot functions, are also possible.
By installing Rexroth's Marex OS optimised for VSP and VCR systems, the new and improved control and handling capabilities are a very attractive prospect for the UK retrofit market, particularly for upgrading tug boats and pleasure craft.
Rexroth has a team of experienced marine engineers available for consultation, whether it's simply for guidance and advice on an application, or to drive a particular control project from beginning to end - concept, design, project planning, classification, installation and commissioning.
