GB 15097-2016Limits and measurement methods for exhaust pollutants from marine engines (China I, II) (English PDF)

1 Scope

GB 15097 is the emission standard for marine engines at the China I and II stages, and it is the document that brought inland and coastal shipping into China's emission control regime. It covers the type test and the information the manufacturer must disclose, the technical requirements and tests, the control of sulphur oxides from ships, production conformity, the engine label, the definition of an engine family and the choice of its parent engine, and the implementation timetable, with ten annexes carrying the test procedures and the rules for inspection, conformity and rebuilding. At 35,000 words it is a certification manual rather than a specification. Issued on 23 December 2016, in force since 1 July 2018; first edition. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the edition it replaces are taken from there. The clause text, the tables and the numeric limits are not reproduced on this page - they are in the document itself, which is delivered in full in English translation.

This standard specifies the emission limits and measurement methods for the exhaust pollutants of compression ignition engines and ignition gas fuel (including diesel and natural gas dual fuel) engines (hereinafter referred to as. marine engines) used for ships. This standard is applicable to the type test, production consistency inspection, durability requirements of category 1 and category 2 marine engines (including main engines and auxiliary engines) which have a rated net power greater than 37 kW for inland vessels, coastal vessels, river-sea ships, channel ships and fishing ships. This standard also stipulates the emission requirements for ships and marine engines after rebuilding. This standard does not apply to emergency marine engines used for ships, marine engines installed on lifeboats, marine engines on any equipment or devices used only in emergency situations. Category 3 marine engines implement the requirements of GD 01. Marine engines which have a rated net power not exceeding 37 kW implement the GB 20891 standard.

3 Terms and definitions

The following terms and definitions apply to this standard.

3.1 Inland vessel Vessels sailing on rivers and lakes.

3.2 Coaster vessel Vessels sailing between coastal ports.

3.3 River-sea ship Ship sailing in coastal waters and river channels.

3.4 Channel ship A ship sailing in the waters across the channels or between islands.

3.5 Fishing ship Refers to ships engaged in fishing production and ships belonging to the aquaculture system serving fishing production, including. fishing ships, breeding vessels, aquatic transportation and sales vessels, refrigerated processing vessels, fishing oil vessels, fishing supply vessels, fishing guidance vessels, fisheries scientific research survey vessels, fisheries teaching practice ship, fishing port engineering ship, fishing tug, fishing transportation ship, fishing barge, fishing administration ship, fishing supervision ship, etc.

3.6 Category 1 marine engine Marine engines which have a rated net power greater than or equal to 37 kW and a single cylinder displacement of less than 5 L.

4 Type test and test information disclosure

4.1 Type of marine engine within the scope of application of this standard shall be subject to type test in accordance with the requirements of this standard.

5 Technical requirements and tests

5.1 General The manufacturer shall take technical measures to ensure that the marine engine's emission control system operates normally under the normal working conditions and within the specified service life; the pollutant emission meets the requirements of this standard.

6 Provisions on the control of sulfur oxide emissions from ships

6.1 Inland vessels, river-sea ships and fishing ships operating in inland rivers shall use diesel fuel that complies with GB 252.

6.2 For coastal vessels, channel ships and fishing ships operating in offshore areas, if marine fuel oil is required for the design of marine engine, it shall use the low-sulfur marine fuel oil complying with national standards and regulations; for ships with pollution control devices, if its sulfur dioxide (SO2) emissions do not exceed the use of low-sulfur marine fuels, it may use other fuels and the ship shall be clearly marked.

6.3 For the ships covered by this standard, if the design of the installed marine engine requires the use of other fuels (such as NG fuel and mixed fuel, etc.), it shall use the commercial fuels that meet the standard.

7 Production consistency inspection

Manufacturers shall take measures in accordance with the requirements of Appendix G, to ensure production consistency. The measured values of engine's gaseous pollutants and particulate matter in the production consistency inspection shall be corrected according to the actual deterioration coefficient (or deterioration correction value).

8 Marine engine's label

8.1 The marine engine manufacturer shall fix a label to each marine engine during production. The label shall meet the following requirements.

8.4 For marine engines that are exempted from type test in accordance with clause 4.3, in addition to meeting the requirements of clauses 8.1 ~ 8.3, the label shall also indicate the purpose and reasons for the exemption.

8.5 Marine engine shall carry a label before leaving the production line after final inspection.

8.6 The location of the marine engine's label is to be described in Appendix A and explained in Appendix F.

9 Determine the parameters of marine engine family

The marine engine family is determined based on the basic design parameters that the marine engines within the family must share. Under certain conditions, some design parameters may affect each other, meanwhile these effects must also be considered, to ensure that only marine engines with similar emission characteristics are included in a marine engine family. Marine engines of the same family shall share the following basic parameters and models.
