L10 - Regulation 13 - NOx Flashcards
What is Regulation 13 of MARPOL Annex VI?
MARPOL Annex VI, Regulation 13, specifically addresses the control of nitrogen oxides (NOx) emissions from marine diesel engines. This regulation sets limits on NOx emissions to reduce air pollution from ships. The limits and conditions under Regulation 13 are categorized based on the engine’s rated speed and the date of installation or major conversion of the engine.
What engines is Regulation 13 of MARPOL Annex VI applicable to?
- Marine diesel engines with a power output more than 130 kW, installed on a ship constructed on or after 1 January 2000.
- Marine diesel engines with a power output more than 130 kW, which undergo a major conversion on or after 1 January 2000.
- Marine diesel engines with an Approved Method, Installed on a ship constructed on or 1 Jan 1990 to 31 Dec 1999.
What engines is Regulation 13 of MARPOL Annex VI not applicable to?
- Emergency marine diesel engines
- Marine diesel engines installed on lifeboats
- Any device or equipment intended to be used solely in case of emergency
- Engines on ships only engaged in domestic voyages can be made subject to alternative NOx control measure or exempted if pre-19 May 2005
What are the Tier limits for NOx?
- Tier I limits apply to engines installed on ships constructed between January 1, 2000, and January 1, 2011.
- Tier II limits apply to engines installed on ships constructed between January 1, 2011, and January 1, 2016.
- Tier III limits apply to engines installed on ships constructed on or after January 1, 2016, but only within NOx ECAs. Outside, Tier II limits apply.
Where are the NOX E.C.As?
- North America ECA + US Caribbean ECA for ships constructed on or after 1 January 2016
- Baltic Sea and North Sea ECAs for ships constructed on or after 1 January 2021.
How to certify and certificates and other regulatory documents?
- Test Bed Exhaust Emission Measurement - Measures engine emissions in the factory.
What is the NOx Technical File?
The NOx Technical File is a comprehensive document required for marine diesel engines to demonstrate compliance with the NOx emission standards set by MARPOL Annex VI.
Information on components, settings,
operating values & adjustments to maintain NOx emissions within allowable limits
If engine is compliant, what is issued?
Engine International Air Pollution Prevention (EIAPP) Certificate
Issued for applicable engines
* Valid for the engines life (unless major
conversion)
What are the methods for onboard NOx compliance?
Engine Parameter Check: Inspecting the engine to make sure it matches its original specifications.
Simplified Measurement: Measuring NOx emissions with samples (rarely used due to complexity).
Direct Measurement and Monitoring: Continuously monitoring NOx emissions (rarely used due to complexity).
What are the list of certificates that have to be kept onboard according to MARPOL VI, to show compliance?
- EIAPP (Engine International Air
Pollution Presentation) Certificate - NOx Technical File
- The above separately for each engine
- Record book of engine maintenance
and changes. - In case of use of SCR (Selective Catalytic Reduction), additional regulatory documents will need to be on-board.
Explain in general terms how IMO regulates NOx from marine diesel
engines.
NOx limits applies to what type of marine diesel engines?
Name the NOx Tiers and their applicability domain.
Tier I limit - engines installed on ships constructed between 01.01.00 and 01.01.11
Tier II - 01.01.11 and 01.01.16
Tier II - on or after 01.01.16 (only the US E.C.A, otherwise TIER II apply
A ship is constructed in 2018. What Tier of NOx will apply to this ship when it is in USA waters? What about the same ship when it is in the
Baltic sea?
Tier III and Tier II
Name the certificates and other documents that a ship should carry in
order to demonstrate that its engines comply with NOx regulations?
