SCHOTTEL unveils PropControl 4 propulsion control system

# What PropControl 4 is SCHOTTEL's PropControl 4 is the next generation of its propulsion control systems. It is a modular platform that brings control functions, user-focused handling, operational reliability and digital connectivity into a single solution. The system targets a broad range of propulsion hardware: azimuth thrusters, transverse thrusters and controllable-pitch propellers.

# Why operators would choose it Vessel operators face more complex propulsion layouts and mixed powertrains. PropControl 4 is presented as a control system that goes beyond basic propeller control to manage modern configurations, including mechanical-hybrid arrangements that combine internal combustion engines and electric motors using Power Take-In (PTI) and Power Take-Off (PTO).

The system also offers a variety of operating modes to fit mission needs — examples called out include straightforward control for dual-fuel engines and specific modes for firefighting operations.

# Operator interface and hardware changes SCHOTTEL redesigned the human interface around day-to-day bridge operations. Key hardware and usability elements:

• A newly developed control lever with improved ergonomics, haptic feedback, integrated status indication and a push-to-talk interface.
• Motorized control levers that support safe desk takeover during operation and give tactile information about operating conditions.
• A user interface that mixes physical and digital touch elements so crews can access complex functions quickly and safely.

For different vessel types and missions, PropControl 4 can use a display-based bridge concept that consolidates functions for multi-propulsion units or a fully haptic button-panel layout where tactile operation without direct visual contact is preferred. Those approaches can be combined and weighted according to customer needs.

# Connectivity, monitoring and maintenance PropControl 4 is built to connect across the vessel lifecycle:

• Internal communication uses CAN bus and Ethernet.
• The system meets cybersecurity requirements cited as IACS UR E27 and IEC 62443-3.
• Internet connectivity enables digital services through the SCHOTTEL Smart Thruster Platform, a shared technology base across SCHOTTEL automation products.
• Operational and telemetry data can be sent to SCHOTTEL MariNet, providing transparency on propulsion condition for maintenance and operational decision-making.
• Secure remote access supports service tasks: retrieving log files, accessing display views remotely, and performing software and parameter updates without being onboard, which shortens fault analysis and improves service planning.

# How PropControl 4 fits fleet needs The product is positioned for vessel owners and operators who need a single, adaptable control platform that handles complex propulsion arrangements and hybridization while giving crews an intuitive interface. The connectivity and monitoring stack is aimed at reducing time-to-fault diagnosis and enabling condition-based maintenance through remote support and telemetry.

# Bottom line PropControl 4 combines modular control logic for varied propulsion assets, operator-focused hardware and interfaces, hybrid propulsion support, and integrated connectivity for lifecycle monitoring and remote servicing. It is presented as a configurable solution that can be tailored to vessel type, mission profile and customer preference.
