PART 3Control of emissions from ships
Ozone-depleting substances
20.—(1) The deliberate emission of an ozone-depleting substance from a ship is prohibited.
(2) For the purposes of this regulation “deliberate emission” includes an emission occurring in the course of maintaining, servicing, repairing or disposing of systems or equipment, but does not include minimal releases associated with the recapture or recycling of an ozone-depleting substance.
(3) New installations which involve the introduction on a ship, other than a United Kingdom ship, of an ozone-depleting substance are prohibited.
(4) Prior to 1st January 2020, paragraph (3) has effect as if after “substance” there were inserted “other than hydrochlorofluorocarbons”.
Nitrogen oxides
21.—[F1(1) Subject to paragraph (2), this regulation applies to every diesel engine with a power output of more than 130 kW which is installed on a ship (a “regulated engine”).]
[F2(2) This regulation does not apply to any engine referred to in paragraph 1 of Schedule 2 and paragraph (4D) does not apply to any engine referred to in paragraph 1A of that Schedule.]
(3) Where a [F3regulated] engine is installed on a United Kingdom ship engaged solely in voyages to ports or offshore terminals within United Kingdom waters, and—
(a)that ship was constructed; or
(b)the engine underwent a major conversion,
before 19th May 2005, the Secretary of State may on application by the owner of the ship direct that this regulation does not apply to that engine.
(4) Subject to paragraph (7), [F4for the purpose of the emission standard set out in paragraph 3 (Tier I) of regulation 13 (nitrogen oxides) of Annex VI,] the operation of a [F5regulated engine to which this paragraph applies] is prohibited, except where the emission of nitrogen oxide (calculated as the total weighted emission of NO2) from the engine is no more than—
(a)17.0 g/kWh when n is less than 130 rpm;
(b)45.0 x n -0.2 g/kWh when n is 130 or more but less than 2000 rpm;
(c)9.8 g/kWh when n is 2000 rpm or more,
where n = rated engine speed (crankshaft revolutions per minute).

(b)was constructed on or after 1st January 2000 and before 1st January 2011; or
(c)underwent a major conversion on or after 1st January 2000 and before 1st January 2011.
(4B) Subject to paragraph (7), for the purpose of the emission standard set out in paragraph 4 (Tier II) of regulation 13 (nitrogen oxides) of Annex VI, the operation of a regulated engine to which this paragraph applies is prohibited, except where the emission of nitrogen oxide (calculated as the total weighted emission of NO2) from the engine is no more than—
(a)14.4 g/kWh when n is less than 130 rpm;
(b)44.0 x n-0.23 g/kWh when n is 130 or more but less than 2000 rpm;
(c)7.7 g/kWh when n is 2000 rpm or more,
where n = rated engine speed (crankshaft revolutions per minute).
(4C) Unless paragraph (4D) applies, paragraph (4B) applies to every regulated engine which is installed on a ship which—
(a)is or was constructed on or after 1st January 2011; or
(b)undergoes or has undergone a major conversion on or after that date.
(4D) Subject to paragraph (7) and Schedule 2ZA, for the purpose of the emission standard set out in paragraph 5 (Tier III) of regulation 13 (nitrogen oxides) of Annex VI (“the Tier III Standard”), the operation of a regulated engine to which this paragraph applies is prohibited, except where the emission of nitrogen oxide (calculated as the total weighted emission of NO2) from the engine is no more than—
(a)3.4 g/kWh when n is less than 130 rpm;
(b)9.0 x n-0.2 g/kWh when n is 130 or more but less than 2000 rpm;
(c)2.0 g/kWh when n is 2000 rpm or more,
where n = rated engine speed (crankshaft revolutions per minute).
(4E) Paragraph (4D) applies to every regulated engine which is installed on a ship which—
(a)is operating in the North American emission control area or the United States Caribbean emission control area and—
(i)is or was constructed on or after 1st January 2016; or
(ii)undergoes or has undergone a major conversion on or after that date;
(b)is operating in the Baltic Sea emission control area or the North Sea emission control area and which—
(i)is constructed on or after 1st January 2021; or
(ii)undergoes a major conversion on or after that date;
(c)is operating in any other emission control area designated by the Marine Environment Protection Committee of the IMO for the purpose of the Tier III Standard and which is constructed or which undergoes a major conversion on or after—
(i)the date of designation of that area; or
(ii)such later date as may be specified in a Merchant Shipping Notice.]
(5) When assessing under paragraph (4) [F7, (4B) or (4D)] the emission of nitrogen oxide from a [F8regulated] engine using fuel composed of blends of hydrocarbons derived from petroleum refining, the test procedure and measurement methods must be in accordance with the NOx Technical Code.
(6) The owner of a ship must ensure that the emission of nitrogen oxide from a [F9regulated] engine that is installed on that ship and that has undergone a major conversion is recorded in accordance with the NOx Technical Code and approved by the Certifying Authority.
(7) Notwithstanding [F10paragraphs (4), (4B) and (4D)], the operation of a [F11regulated] engine is permitted when either an exhaust gas cleaning system or any other equivalent method, approved in accordance with [F12the Merchant Shipping (Marine Equipment) Regulations 2016], is applied to [F13the engine in question to meet the applicable emission standard in paragraph (4), (4B) or (4D), respectively].
