Main reduction gears are inspected by NAVSEA at what interval?

Main reduction gears are inspected by NAVSEA at what interval?

• A. Every five years
• B. Every ten years or when conditions warrant
• C. Every year
• D. Every three years

Answer: (B)

Main reduction gears are critical components in a ship's propulsion system, and their inspection is governed by specific maintenance guidelines established by NAVSEA (Naval Sea Systems Command). The directive states that these gears should be inspected every ten years, or when conditions warrant, such as after significant operational stress or in response to specific technical issues that may arise. This interval is based on the understanding that the gears undergo wear and tear over time, and routine inspections help ensure that any potential problems are identified and addressed before they lead to operational failures. Regular inspections are essential to maintain the functionality of the gear system while extending its service life. The ten-year interval also reflects a balance between ensuring operational readiness and managing maintenance resources effectively.
