According to 33 CFR Part 155, a 1500 gross ton freight vessel, with a keel laid in 1969, must have a fuel oil discharge containment for the fuel tank vents. This containment must consist of __________.
• 33 CFR Part 155 requirements for fuel oil tank vent containment on existing freight vessels • How capacity is specified for fixed containment systems (barrels vs. gallons vs. height) • Differences between drainage devices, portable containers, and permanently installed containment
• Which options describe permanent, fixed containment designed to catch and hold an overflow from fuel tank vents? • For a 1500 GT freight vessel with keel laid in 1969, would the regulation more likely specify a dimension/volume standard or just a general device type (like scuppers)? • Look at which option directly states a required capacity linked to the number/size of vents rather than just a general feature.
• Verify in 33 CFR Part 155 the exact wording of the fuel oil discharge containment requirement for tank vents on existing freight vessels of this size and age. • Check which answer choice mentions a specific minimum volume related to vent size (inside diameter in inches) rather than just a physical feature (like coamings or drains). • Confirm that the chosen option clearly functions as spill containment for vent overflows, not just general deck drainage or protection.
