🔍 Key Concepts

• High-pressure fuel oil systems on diesel engines and their fire risk • Regulatory limits for pressure pulsations in fuel return piping • Requirements for shielding, routing, and relieving fuel oil return lines

💭 Think About

• Compare which options deal with preventing fuel spray or mist from reaching hot surfaces versus just routing fuel back to tanks. • Think about whether regulations usually allow high-pressure fuel to return directly into day/settling tanks, or if there are special safety requirements first. • Consider what happens if a high-pressure return line fails near an engine—what is the main hazard the regulation is trying to control?

✅ Before You Answer

• Identify which choice specifically addresses fuel mist / spray and ignition sources, not just tank arrangements. • Check whether any option conflicts with typical rules against putting valves or restrictions in fuel return lines that could increase pressure. • Verify which option matches common SOLAS/USCG language about shielding or protecting fuel lines from spraying on hot surfaces.

Question 1 of 20

If the peak to peak pressure pulsation in the diesel engine fuel injection return piping exceeds 285 psi what special provision is to be provided?

The piping shall be shielded and secured to prevent fuel or fuel mist from reaching a source of ignition on the engine or its surroundings.

The piping shall be directed to the fuel oil day tank, in addition it shall enter below the normal operating level of the tank.

Most diesel injection systems do not develop high pressures in their return lines due to regulations prohibiting installation of valves in these lines.

Return piping is required to be protected by relief valves which relieve to the diesel oil settling tank.
