Which of the following statements is correct...

🔍 Key Concepts

• ABS rules for diesel fuel oil systems – what they generally require for safety and fire protection • Typical requirements for remote fuel oil shutoff valves at service tanks on diesel vessels • General engineering practice for high‑pressure fuel injection lines (pipe type and where strainers are/are not placed)

💭 Think About

• Which options describe features that improve fire safety and allow fuel to be shut off quickly in an emergency? • For very high‑pressure fuel injection lines, is it more common to use seamless or seamed pipe, and why? • Would putting a cleanable strainer directly in a high‑pressure injection pump discharge line while the engine is running be considered safe and typical practice?

✅ Before You Answer

• Verify in ABS rules where remote‑operated shutoff (cut‑out) valves must be located and from which deck or platform they must be operable • Check whether ABS allows seamed pipe on high‑pressure injection lines, or if seamless is the norm • Confirm whether ABS requires or even permits strainers in the injection pump discharge line, especially ones cleaned while the engine operates

Which of the following statements is correct concerning ABS rules for fuel oil injection systems as found on diesel propelled vessels?

Check valves are to be located at the service tank and be so arranged as to be operable from the uppermost platform of the engine compartment.

Cut-out valves are to be located at the service tanks and be so arranged as to be operable from the engine room floor plates.

Strainers are to be provided in the fuel oil injection pump discharge line and shall be capable of being cleaned while the engine is in operation.

The injection line is to be of seamed drawn pipe and fittings are to be extra heavy.
