Which of the following statements is true concerning the instrumentation or alarms provided at the main control station for an automated main propulsion plant?
• 46 CFR requirements for automation of main propulsion plant • Purpose of testing alarms and indicating lights on control systems • Difference between vital and nonvital alarms in machinery spaces
• Ask yourself which options describe safety‑critical good practice for ANY automated propulsion plant, regardless of specific vessel type. • Consider whether alarms and circuits should ever be intentionally disabled during normal operation of an automated plant. • Think about whether regulations tend to require the ability to TEST alarms, or just to have them installed.
• Verify which items are explicitly required in 46 CFR for automated propulsion control systems. • Check whether regulations require separation of vital and nonvital alarms or just recognizable distinction between them. • Confirm if there is a requirement that all alarm circuits be active whenever the system is in service.
