What is the NOx Technical Code?

NOx TECHNICAL CODE (2008) Technical Code on Control of Emission of Nitrogen Oxides from Marine Diesel Engines.

What are the regulation regarding NOx in Reg 13 Annex VI?

The revised Annex VI has also introduced the prospect of retrospective NOx certification, regulation 13.7, in the case of diesel engines of more than 5000 kW power output and a per cylinder displacement of 90 litres and above installed on ships constructed between 1 January 1990 and 31 December 1999.

What is the NOx limit?

The EPA established the statewide NOx budgets using recommendations from OTAG on how to reduce emissions from utilities and other sources of NOx. EPA’s rule is consistent with OTAG’s recommendation for utilities: an emission rate limitation as low as 0.15 lbs/mmBtu or, 85% from sources 1990 emissions rate.

What is NOx in Marine?

Nitrogen Oxides or NOx Pollution The ignition source in the marine engine is the compression stroke of the piston, after which, the combustion begins. As the air mixture is 21 % Oxygen and 78% Nitrogen, nitrogen reacts with oxygen under certain engine operating conditions to form Nitrogen oxides or NOx.

What is IMO Regulation 2020?

Known as “IMO 2020”, the rule limits the sulphur in the fuel oil used on board ships operating outside designated emission control areas to 0.50% m/m (mass by mass) – a significant reduction from the previous limit of 3.5%. Within specific designated emission control areas the limits were already stricter (0.10%).

What is IMO Tier 1?

Under the 2008 Annex VI amendments, Tier I standards become applicable to existing engines installed on ships built between 1st January 1990 to 31st December 1999, with a displacement ≥ 90 liters per cylinder and rated output ≥ 5000 kW, subject to availability of approved engine upgrade kit.

What are IMO requirements?

The new regulations, known as IMO 2020, mandates a maximum sulphur content of 0.5% in marine fuels globally. The driver of this change is the need to reduce the air pollution created in the shipping industry by reducing the Sulphur content of the fuels that ships use.
