🔍 Key Concepts

• Cargo piping terminology on tank vessels • Difference between common lines (serving multiple tanks) and dedicated lines (serving one tank) • How cargo is routed from the manifold to individual tanks

💭 Think About

• Which term best describes a line that is dedicated to a single tank, not shared? • Think about where the line physically goes: from the manifold down into one tank—what do mariners commonly call that vertical or direct run? • Which of these terms is most often associated with branching off a main header versus being the actual drop into the tank?

✅ Before You Answer

• Identify which option clearly means it serves only one tank instead of several tanks • Ask yourself which term is commonly used for the vertical run from deck level into the tank on cargo systems • Eliminate any choice that usually refers to a section off a main line that could serve multiple tanks rather than a single dedicated run
