What kind of discharge is used in basic?

• A. In-discharge
• B. Overboard discharge
• C. Internal discharge
• D. External discharge

Answer: (A)

The concept being tested is how discharge is handled within shipboard systems during basic training. In-discharge refers to routing waste or fluids into the ship’s own internal sanitary or bilge systems rather than releasing anything over the side or to the external environment. This keeps operations compliant with environmental rules and safety protocols while in port or under training conditions. Releasing overboard or externally would violate those rules, so those options aren’t used in basic. Internal discharge describes discharge within the ship’s spaces or systems, but the term used in this context emphasizes keeping the discharge contained in the vessel’s own infrastructure.
