🔍 Key Concepts

• Cargo piping systems on tankers and how oil moves from the manifold into the main underdeck system • Difference between main lines, branch lines, and drops/fills in a cargo system • Where the manifold is located and what its purpose is during cargo transfer

💭 Think About

• Visualize the cargo system: starting at the shore connection/manifold, what is the very first section of piping that leads into the ship’s underdeck lines? • Think about the word parts in each option (e.g., does it sound like a main run of pipe, a smaller offshoot, or a vertical connection?). • On a typical tanker line diagram, what is the name of the piece of piping that connects the manifold directly to the underdeck piping before it splits off to individual tanks?

✅ Before You Answer

• Be clear on what the manifold is and where it is located on deck. • Identify which term usually refers to the main connection between the manifold and the underdeck piping, not the smaller offshoots. • Eliminate any option that sounds more like a connection into a single tank rather than into the main underdeck system.
