Question 623General Subjects - Assistant Engineer
70% to passIn accordance with the international MARPOL Annex VI regulations, the sulfur content of any fuel oil used onboard ships shall not exceed what percentage by weight?
A1.5%
B3.0%
C4.5%
D6.0%
AI Explanation
The correct answer is C) 4.5%. The international MARPOL Annex VI regulations limit the sulfur content of fuel oil used onboard ships to not exceed 4.5% by weight. This is the global sulfur cap set by MARPOL Annex VI to reduce air pollution from ships and protect the environment. The other answer choices are incorrect because 1.5% is the lower sulfur limit for Emission Control Areas (ECAs), 3.0% is not a valid global sulfur limit under MARPOL, and 6.0% would exceed the current 4.5% global sulfur cap.
