Question 1 of 27070

Every U.S. crude oil tankship with a keel laying date on or after 1/1/75, shall be equipped with an inert gas system if the tonnage is more than __________.

🔍 Key Concepts

• 46 CFR requirements for inert gas systems on tankships • Difference between deadweight tonnage (DWT) and other tonnage measures • Pay attention to whether the regulation uses metric tons or long tons

💭 Think About

• Look up the specific 46 CFR section that covers inert gas systems for crude oil tankships built after 1/1/75. What exact threshold tonnage and units are stated there? • Think about how U.S. regulations typically express deadweight tonnage for international trade vessels: do they favor metric tons or long tons in modern rules? • Compare the options: two use 50,000 and two use 100,000, and each pair splits by metric vs long tons. Which combination matches the CFR wording?

✅ Before You Answer

• Confirm the exact numeric threshold in 46 CFR (50,000 or 100,000) • Confirm whether the regulation specifies DWT in metric tons or DWT in long tons • Make sure you are looking at the section that applies specifically to crude oil tankships and to keel laid on or after 1/1/75
