Schottel has unveiled PropControl 4, the latest generation of its propulsion control systems, designed to help operators and crews manage increasingly complex propulsion systems safely, efficiently, and intuitively.
It combines powerful control functions, user-friendly handling, high operational reliability, and digital connectivity within a single platform. Designed for azimuth thrusters, transverse thrusters, and controllable pitch propellers, the system can be modularly adapted to a range of vessel types and propulsion configurations, ensuring the appropriate functions and operating modes for any propulsion configuration.
Alexander Neideck, Product Management Automation and Digital Products, said: “With PropControl 4, we are introducing a new generation of propulsion control that makes complex functions easily accessible and intuitive for operators. Crews benefit from intuitive operation, while operators are provided with a future-ready platform designed to deliver high availability and integrated safety throughout the vessel’s entire lifecycle.”
The growing focus on more efficient vessel and propulsion solutions presents operators with new challenges in terms of control and automation. With PropControl 4, Schottel says it offers a control system for applications that go beyond conventional propeller control. For example, the system supports mechanical-hybrid propulsion concepts, that is, the combination of combustion engines and electric motors through power take-in (PTI) and power take-off (PTO) functions. In addition, a range of operating modes is available for different application requirements, enabling, among other things, straightforward propulsion control of dual-fuel engines, the use of the propulsion system during firefighting operations, and various other applications.
PropControl 4 has been designed around the requirements of day-to-day vessel operation. An interactive user interface combining physical and digital touch elements offers intuitive operation and helps crews use complex functions quickly and safely. A key feature is the newly developed control lever, offering improved ergonomics, haptic feedback, status indication and an integrated push-to-talk interface. Important operating conditions can be felt directly through the lever. In addition, the motorised control levers enable intuitive and safe desk takeover during operation. An integrated status indicator on the lever provides an at-a-glance overview of the propulsion system’s operating status.
PropControl 4 offers operating concepts that can be adapted to the respective application profile. For vessels with multiple propulsion units, such as offshore vessels, a display-based control concept allows key functions to be consolidated and integrated on the bridge in a space-saving manner. Alternatively, a fully haptic operating interface based on proven button panel technology is available. This solution is suited to workboats where crew members frequently operate the system without direct visual contact with the controls, making fully tactile elements the preferred choice. Depending on vessel type, mission profile and customer requirements, both approaches can be combined and weighted differently, enabling a tailor-made operating solution for any application.
For operators and crews, the system’s redundant safety architecture delivers maximum availability. Redundant design of lever electronics, PLCs, and wiring ensures that vessels can continue to be operated via the familiar control lever in the event of a system failure. This preserves the established operating logic in critical situations, reducing crew workload and eliminating the need for additional training for backup operation.
The system complies with current cybersecurity requirements in accordance with IACS UR E27 and IEC 62443-3. Internal communication is based on CAN bus and Ethernet technologies. In addition, PropControl 4 can be connected to the internet, enabling a range of additional digital services and functionalities. The system is based on Schottel’s Smart Thruster platform, a shared technology platform for hardware, software, and processes across Schottel’s automation portfolio. It creates synergies between applications and provides operators with a future-proof foundation for the long-term efficient operation of their vessels. Accordingly, PropControl 4 comes equipped with advanced monitoring, data, and support capabilities. Operational and telemetry data can be collected and transmitted to Schottel MariNet. This provides operators with greater transparency regarding the condition of their propulsion systems and allows maintenance and operational decisions to be based on reliable data. Additional connectivity features enable secure remote access for service and maintenance purposes. Log files and system information can be retrieved, display views can be accessed remotely, and software and parameter updates can be performed without being onboard. This enables faster fault analysis and more efficient planning and execution of service interventions.
