FM services include which combination?

• A. Ballasting/compensation and drainage
• B. Seawater cooling system only
• C. Ballasting/compensation, drainage system, seawater cooling system
• D. Fuel oil heaters

Answer: (C)

FM services on a ship cover the essential service systems that keep the vessel alive and comfortable in operation: ballast/compensation, drainage, and seawater cooling. Ballasting/compensation manages ballast water to keep the ship stable and properly trimmed as load and conditions change. The drainage system removes leaked or wastewater so spaces stay dry and safe. The seawater cooling system uses seawater to remove heat from engines and other machinery, preventing overheating. Together, these three systems provide the full set of services included under FM services. Leaving out any one of them breaks the coverage, and systems like fuel oil heaters belong to the fuel/fuel-air side of the plant rather than FM services.
