Which statement best describes the PMS in relation to the 3-M system?

• A. It is a separate system not part of 3-M.
• B. It is optional for ships to use.
• C. It only tracks inventory.
• D. It provides a standardized method for implementing all preventative maintenance performed by the Ship's Force.

Answer: (D)

The main idea is that the Planned Maintenance System (PMS) is the standardized way the 3-M system gets preventive maintenance done by the ship’s crew. It sets the uniform procedures, intervals, and documentation for every PM task, so all maintenance is performed consistently and traceably. This makes sure tasks are completed on schedule, using the correct instructions, and that results are recorded for accountability. It isn’t a separate system or an optional add-on, and it’s broader than just tracking inventory—PMS actively guides the execution of all preventive maintenance by the Ship’s Force.
