Question 20 TK02 - Tank Vessel Assistant - Liquefied Gas

The Correct Answer is A **Explanation for Option A (crossover):** The term "crossover" in tank vessel piping refers specifically to the pipe or arrangement of piping that allows fluid (such as cargo) to be moved from one main piping system or manifold (typically the port side) to another main piping system or manifold (typically the starboard side), effectively connecting two separate systems. This is essential for flexibility in loading, discharging, or transferring cargo between tanks or systems. **Explanation for Option B (connection):** "Connection" is a generic term describing where any two items join. While a crossover is a type of connection, it is not the specific, technical name for the piping arrangement that joins the main port and starboard systems on a tank vessel. **Explanation for Option C (junction):** "Junction" generally means a point where paths meet or divide (like a 'T' or 'Y' branch). While part of a crossover system may include junctions, "junction" does not describe the entire system designed to bridge the two main port and starboard lines. **Explanation for Option D (transfer):** "Transfer" is an action (the movement of fluid from one place to another). While the crossover pipe is used to facilitate a transfer of cargo, it is not the name of the pipe itself. The pipe is the crossover.
