Why is controller redundancy necessary?
The most common cause of breakdowns on ships is mechanical damage. Therefore, it is extremely important for container ships, tankers, bulk carriers and cruise ships to have reliable systems on board. The current rules of classification societies like DNV GL and ABS require sufficient redundancy for so-called “essential functions.”
Redundant controllers can help previous system failures. Specialists and spare parts are often lacking on scholarships – a back-up controller immediately takes over the control tasks. This prevents downtime and the resulting costs.
Benefits of Controller Redundancy
Increases availability in the automation system
Reduces/prevents failures and their effects
Significantly improves operational reliability
