🔍 Key Concepts

• Pipe tunnel layout and purpose on cargo and tanker vessels • How pipes are routed between the machinery space and distant compartments • Access for inspection, maintenance, and damage control along pipe runs

💭 Think About

• Look at which option best describes the overall function of a pipe tunnel, not a narrow or specialized purpose like just insulation or segregation. • Ask yourself: on a ship, why would designers want a person to be able to walk along or reach all the fore‑and‑aft piping from the engine room? • Consider which choice matches the idea of centralizing many lines (fuel, ballast, fire main, etc.) into a space where they can be controlled and repaired in an emergency.

✅ Before You Answer

• Which choice talks about multiple pipes running fore and aft from the machinery space? • Which option emphasizes access and control/maintenance instead of only protection or insulation? • Eliminate any option that sounds like it only applies to one pipe or one specific compartment, since pipe tunnels typically serve more than a single line.
