Question 1 of 31093

Q

What material is allowed in construction of the hull of a vessel with an integral diesel fuel tank?

🔍 Key Concepts

• 46 CFR regulations for diesel fuel tanks and fuel systems on small passenger and inspected vessels • Requirements for integral fuel tanks (tanks that are part of the hull structure) versus independent tanks • Which hull materials are commonly accepted for fuel tank boundaries in contact with diesel fuel

💭 Think About

• Look at which materials are typically used for the hull structure of inspected vessels and can safely form one side of a diesel fuel tank. • Consider whether any materials listed might react poorly with diesel fuel or be structurally unsuitable as a tank boundary. • Ask yourself: if the hull plating is also the tank wall, which of these options is most consistent with standard shipbuilding practice and USCG regulations?

✅ Before You Answer

• Verify in 46 CFR what materials are specifically mentioned as acceptable for integral diesel fuel tanks that are part of the hull. • Check whether non-metallic sandwich constructions with soft cores are permitted as fuel tank boundaries in contact with diesel. • Confirm whether copper-based alloys are normally used as primary hull plating material on inspected vessels.
