Cyber-Secure Engine Supervision Systems for Modern Marine Propulsion

The InteliDrive 700 Marine serves as a dedicated Engine Supervision System (ESS) designed to interface with electronic and mechanical engines. This technology facilitates the management of power units up to 10 MW, supporting fixed and variable speed configurations. By integrating this system into the automotive data ecosystem of a vessel, operators can manage propulsion, auxiliary, emergency, and harbor engines through a unified hardware architecture.

Technical Integration and Connectivity Standards
Integration into the digital supply chain of maritime operations is achieved through an open architecture that prioritizes standardized communication protocols. The system utilizes Ethernet with Modbus Master communication and multiple CAN bus interfaces. These interfaces support J1939 protocols for Engine Control Unit (ECU), Remote Protection Unit (RPU), and I/O integration.

The hardware supports two plug-in expansion modules, allowing for the addition of GPS tracking, three-phase voltage measurement, and extended binary I/O. When paired with the InteliGen 1000 Marine power management system, the ESS enables synchronized on-board communication, ensuring that engine performance data and power distribution metrics are processed within a single cohesive environment.

Safety Protocols and Cybersecurity Compliance
To address the increasing requirements for maritime cybersecurity, the system incorporates user access management and secure communication layers. Safety is managed through the Inteli RPU G2, a dedicated safety shutdown module that operates independently of the primary control logic to ensure fail-safe performance.

The system provides comprehensive alarm monitoring and an extensive history log to facilitate diagnostic analysis. These technical measures are designed to maintain maximum engine uptime in commercial operations by allowing for rapid troubleshooting and preventing unauthorized configuration changes.

Application and Customization
While the system includes preprogrammed logic for standard marine applications, it features an integrated Programmable Logic Controller (PLC). This allows technical teams to customize control sequences to meet specific vessel requirements without replacing the core hardware.

The ecosystem is supported by a range of human-machine interfaces, including the InteliVision 5.2, 1050, and 1550 Marine displays. These units provide multi-controller support, allowing operators to monitor several engine parameters from a centralized location. To streamline panel production, the I-RB8 G2 relay board is utilized to organize control wiring, reducing the physical footprint of the installation.
