Kongsberg MP7900 w/LAN/CAN Operator Station CPU

Description:

The Kongsberg MP7900 w/LAN/CAN is a discontinued remote workstation computer specifically designed for the Kongsberg K-Chief 500 marine automation system. The Kongsberg MP7900 is a rugged, marine-grade Operator Station CPU (Central Processing Unit) used as the primary computer for various Kongsberg Maritime systems.1 It is the “brain” of the Human-Machine Interface (HMI), processing data from sensors and translating it into the visual graphics seen on the control room monitors.

Technically, the MP7900 is often a customized version of the HP Compaq dc7900 Small Form Factor (SFF) PC, specially adapted and certified for maritime use.2

Core Applications

The MP7900 is found across almost all major Kongsberg maritime platforms:

K-Chief 600 / 700: Acts as the Operator Station (OS) for marine automation and engine monitoring.3

K-Pos Dynamic Positioning: Serves as the processing unit for DP control systems.4

Power Management Systems (PMS): Handles logic for load sharing and generator control.

K-Bridge: Used in Integrated Bridge Systems (IBS) for navigation and conning displays.5

Maintenance & Troubleshooting

Redundancy: In many K-Chief or DP setups, MP7900 units are installed in pairs. If one fails, the system should automatically switch to the standby station.

Environmental Protection: These units are designed to withstand the vibration, humidity, and temperature fluctuations of a ship’s bridge or engine control room.6

Backup/Restore: Maintenance manual 328925J (often provided with the vessel’s technical documentation) details the procedure for using a USB recovery stick to restore the system image if the hard drive fails.
