Which equipment is listed as LOQM weekly tested equipment? (Choose the correct grouping)

• A. Air compressors
• B. MRG, LSB, Steam Turbines
• C. Pumps
• D. Generators

Answer: (A)

Weekly LOQM tested equipment are those whose ready status must be verified frequently because a failure would immediately impact many ship systems. Air compressors fit this because they supply the pneumatic power for instrument air, safety interlocks, valve operation, and starting air. They typically operate under varying loads and are sensitive to moisture, contaminants, and filter condition, so regular weekly checks help ensure they stay within specification and catch issues early. The other items listed—main reduction gear and related machinery, steam turbines, pumps, and generators—are larger, more complex systems that generally require longer maintenance cycles and more in-depth inspections, so they aren’t grouped for weekly LOQM testing.
