The SSTG condensers are part of which seawater circulating system?

• A. Auxiliary seawater circulating system
• B. Main seawater circulating system
• C. Emergency seawater system
• D. Fuel oil cooling system

Answer: (A)

SSTG condensers are cooled by the auxiliary seawater circulating system because the Steam Turbine Generator is an auxiliary piece of equipment, and its condenser needs a dedicated cooling loop separate from the main propulsion plant. The auxiliary seawater system provides cooling for auxiliary machinery, including the SSTG, while the main seawater system serves the propulsion plant condensers. The emergency seawater system is a backup, not the normal cooling path for SSTGs, and the fuel oil cooling system uses seawater to cool oil heaters, not to condense the SSTG exhaust. So the SSTG condenser belongs to the auxiliary seawater circulating system.
