Which equipment is tested weekly under LOQM?

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

Answer: (A)

Weekly LOQM testing targets equipment whose readiness can be verified quickly and whose failure would immediately affect many systems. Air compressors fit that role because they provide essential starting air and power for numerous pneumatic functions across the ship. A quick weekly check can confirm the compressor starts reliably, reaches the required discharge pressure, maintains pressure, and that safety interlocks and controls are functioning. While you can also inspect oil levels, filters, belts, and look for leaks in a short session, the goal is a rapid, repeatable readiness test that covers the most commonly used pneumatic services.

In contrast, while steam turbines, large gear assemblies, and pumps are critical, they require more extensive, specialized maintenance and longer testing cycles due to their complexity, safety considerations, and the need for detailed lubrication and performance checks. That’s why they aren’t typically scheduled on a weekly LOQM cadence.
