Pollution Prevention Regulations (33 CFR Part 155) state that no person may transfer oil or fuel to a vessel of 300 gross tons or more, constructed after June 30,1974, unless each fuel tank vent, overflow, and fill pipe is equipped with a/an __________.
• 33 CFR Part 155 – Oil or Hazardous Material Pollution Prevention Regulations for Vessels • Design features that prevent oil/fuel from spilling out of vents, overflows, or fill pipes during bunkering (fueling) • Difference between fixed/built-in equipment and portable/temporary equipment for pollution prevention
• When a large vessel (300 GT or more) is being fueled, what is the greatest spill risk at the vent, overflow, and fill pipe? What kind of device directly addresses that risk? • Look at each choice: which are permanently installed parts of the vessel’s system, and which are temporary or handheld items used only during fueling? • Which option is specifically designed to automatically stop or control flow when tanks are near full, rather than just ‘catch’ or ‘contain’ a spill after it happens?
• Verify in 33 CFR Part 155 that the requirement applies to vessels 300 gross tons or more, constructed after June 30, 1974 – make sure the condition matches the question. • Check which device must be equipped on each fuel tank vent, overflow, and fill pipe – not just on deck generally or around manifold connections. • Confirm whether the regulation calls for a fixed/installed shutoff or control device versus a portable containment measure that can be moved around.
