🔍 Key Concepts

• Emission Control Area (ECA) fuel sulphur limits under MARPOL Annex VI / local ECA rules • The difference between the time of arrival/crossing the line and the time required for fuel system flushing and changeover • What it means to be in compliance at the moment you enter the ECA

💭 Think About

• Think about whether the regulation cares about when you start the changeover, or about the sulphur content actually being burned once you are inside the ECA. • On a slow-speed diesel, does the fuel system instantly switch to compliant sulphur levels at the line, or does it take time to flush previous fuel from lines, pumps, and heaters? • Which option best reflects the need to be fully compliant right at or before the moment of entry, considering the time needed for the physical changeover process?

✅ Before You Answer

• Verify that the vessel must already be burning compliant fuel at the point of entry into the ECA, not just have started changing over. • Consider how long it takes to flush the fuel system so that the fuel at the engine actually meets the sulphur requirement. • Check which option focuses on ensuring compliance in practice, rather than naming a specific fixed time like “one hour” or “at arrival”.

Question 1 of 20

When entering a ECA, when should you begin the changeover to low sulphur fuel on a slow-speed diesel vessel?

At Arrival.

An hour before crossing the demarcation line for low sulphur fuel.

In sufficient time to ensure the engine is burning a fuel mixture of sufficiently low sulphur to meet the regulatory requirement.

When the vessel crosses the demarcation line.
