🔍 Key Concepts

• MARPOL Annex VI – Regulation 13 (NOx) applicability criteria • The power rating threshold (in kW) at which NOx rules start to apply • Specific exemptions for engines used only in emergencies or for lifesaving appliances

💭 Think About

• First, decide whether the NOx rules are triggered by engines above or below a certain kW rating. Which side of 130 kW is covered? • Next, think about why the regulations might treat emergency and lifesaving engines differently from normal propulsion or generator engines. • Ask yourself: Among the listed options, which engines are meant for routine operation versus only during emergencies or drills?

✅ Before You Answer

• Verify the exact kW threshold in MARPOL Annex VI Reg. 13 for diesel engines subject to NOx limits. • Check whether emergency diesel-generator engines are fully subject to the NOx limits or explicitly exempted. • Check whether lifeboat engines are covered by MARPOL Annex VI NOx rules or specifically exempt as lifesaving appliances.
