Totem Plus IMACS – Integrated Monitoring, Alarm and Control System

The Totem Plus IMACS (Integrated Monitoring, Alarm and Control System) is a highly advanced and comprehensive system designed for engines and machinery on board ships. This system combines Siemens PLC units, PC computers, and powerful software to provide a range of integrated features for efficient operation. One of the key highlights of the Totem Plus IMACS is its use of Commercial-Off-The-Shelf (COTS) hardware. This eliminates the need for specialized and expensive marine spare parts, making service and repairs much easier and accessible worldwide. Fault finding and maintenance are simplified with the SIMATIC-S7 PLC Push-Pull modules that can be quickly replaced if needed. The system operates on a common network, connecting all workstations, and allowing each station to take control of the entire system independently, even in the event of failure in other stations. Additionally, other computers on the ship’s LAN can log into the system for monitoring purposes, enhancing flexibility and accessibility.

The Totem Plus IMACS offers a wide range of functionalities beyond the standard engine monitoring and automation features. It integrates Power Management System, Tank Level indication, Anti Heeling, and Loading program, providing a comprehensive solution for ship operations. The system also includes a shore-side “Office” version that enables offline data analysis and fault diagnostics. With full redundancy of CPU and BUS, the system ensures automatic takeover in case of PLC failure, enhancing reliability and system continuity. Furthermore, its open architecture allows for easy adaptation and fitting to any type of vessel.
