Q

(1.2.15-9) On US flag steam propulsion vessels, the main reason for having a low suction line on the fuel oil service or settling tanks is to accomplish which of the following?

🔍 Key Concepts

• Fuel oil service tanks vs settling tanks and what each is designed to do • Behavior and location of water and sludge in fuel tanks compared to usable fuel • How suction line height affects what actually gets drawn into the system

💭 Think About

• In a settling or service tank, where does water and sludge naturally collect, and how would the height of the suction affect whether you pick it up? • If you lower the suction line, which of the answer choices would be helped, and which might actually be made worse? • Think about rough weather: would a lower suction help keep suction, or increase the risk of pulling unwanted contaminants?

✅ Before You Answer

• Be clear on the primary purpose of a settling tank (what is it supposed to remove or separate?). • Visualize a cross‑section of the tank: fuel on top, water/sludge at the bottom – where would you ideally want the suction relative to that interface? • Check which option best matches standard good engineering practice for protecting the fuel system and burners from contamination.
