Introduction to Global Sulfur Control Areas

2021-11-03Views:1385

Many friends have given feedback that due to a lack of understanding of the latest global emission control areas and the latest emission policies, it is easy for ships to be fined or detained by local PSCOs. This issue tries to collect and summarize the latest information on the scope of emission control areas and emission requirements around the world and present it to everyone.

According to the International Ship & Offshore Network, the preparations for the 5th Shanghai 2020 Summit on Marine Ballast Water Systems (BWMS) and Scrubbers will be held on December 2-3.

What is the purpose of a ship emission control area?

The main purpose of establishing a ship emission control area is to improve the air quality in coastal and riverine areas, especially in port cities, by controlling the emissions of sulfur oxides, nitrogen oxides, and particulate matter from ships navigating, berthing, and operating within the emission control area, and to promote energy conservation, emission reduction, and the development of green shipping.

Two

Why control the emission of air pollutants from ships?

Relevant studies show that atmospheric pollutants emitted by ships mainly originate from exhaust gases produced by ship power systems, cargo volatilization during transport, and onboard burning. The atmospheric pollutants generated are primarily sulfur dioxide (SO2) and nitrogen oxides (NOx), and also contain certain amounts of inhalable particulate matter (PM10), fine particulate matter (PM2.5), carbon monoxide (CO), volatile organic compounds (VOCs), and other atmospheric pollutants, as well as greenhouse gases mainly composed of carbon dioxide (CO2). At present, domestic and international research on controlling ship air pollution mainly focuses on SO2, NOx, and PM. Among them, SO2 is derived from the sulfur in ship fuel, so SO2 emissions are directly related to fuel type, fuel quality, and consumption. NOx is mainly produced by the oxidation of nitrogen in the air during rapid combustion and high-pressure conditions, and its emissions are closely related to the engine and its operating conditions. Particulate pollutants such as PM10 and PM2.5 include primary particles such as directly emitted black carbon and heavy metals, as well as secondary particles formed through chemical reactions, such as sulfates, nitrates, and secondary organic matter, which can be formed from SOx and NOx. Controlling the sulfur content in ship fuel is an effective means to reduce sulfur oxides and particulate emissions from ship engines and is currently the main method for controlling ship air pollution both domestically and internationally.

Three

What are the ship emission control areas?

After extensive research, the editor found that there are currently six internationally recognized emission control areas. In addition, countries such as China, South Korea, Norway, Iceland, and Turkey have also established corresponding emission control areas and emission standards. The six main ones among these include:

Established with the approval of the International Maritime Organization

The Baltic Sea region

Beihai sea area

North American waters

Caribbean Emission Control Area

Approved by the European Union

European Sea Emission Control Area

Approved for establishment in the United States

California Emission Control Area, USA

All six of the above regions require the use of fuel with a sulfur content of less than 0.1%.

In addition to the above six, the following areas also need to use fuel with a sulfur content of less than 0.1%:

4. China's Latest Emission Control Areas

On December 20, 2018, the Ministry of Transport of China issued the "Implementation Plan for the Control Area of Atmospheric Pollutant Emissions from Ships" and clarified the scope of the control areas and the control requirements as follows:

1. Emission Control Area:

China's scope of control areas for ship atmospheric pollutants has further expanded the geographical range of control based on the already established ship emission control areas in the Bohai Sea (Beijing-Tianjin-Hebei), Yangtze River Delta, and Pearl River Delta waters, including coastal control areas and inland river control areas of China.

China's coastal control areas and inland river control areas are shown in the left image, and the right image shows the scope of Hainan control area:

China Inland Waterway Control Zone

2. Requirements for the control of sulfur oxide emissions from ships:

1. Starting from January 1, 2019, ships entering coastal control zones shall use marine fuel with a sulfur content not exceeding 0.5% m/m.

2. Starting from January 1, 2020, seagoing vessels entering inland emission control areas shall use marine fuel oil with a sulfur content not exceeding 0.1% m/m.

3. From January 1, 2022, ships entering the controlled waters of Hainan must use ultra-low sulfur oil with 0.1% m/m.

4. From January 1, 2025, ships entering coastal control zones shall use marine fuel with a sulfur content not exceeding 0.1% m/m. (This provision has not yet been implemented and is currently under evaluation)

3. In addition, regulations have also been made for the emission of nitrogen oxides:

a.January 1, 2000and subsequent constructions (based on the time of keel laying) or major modificationsInternational navigation ships, for single engines with a power greater than 130 kilowatts, it should comply with the 'International Convention for the Prevention of Pollution from Ships'tier-IRegarding the emission standards for nitrogen oxides.

b.January 1, 2011and subsequent constructions (based on the time of keel laying) or major modificationsInternational navigation ships, for single engines with a power greater than 130 kilowatts, it should comply with the 'International Convention for the Prevention of Pollution from Ships'tier-IIRegarding the emission standards for nitrogen oxides.

c.March 1, 2015and subsequent constructions (based on the time of keel laying) or major modificationsDomestic vessels of Chinese nationality, for single-engine power greater than 130 kilowatts, it should comply with the 'International Convention for the Prevention of Pollution from Ships'tier-IIRegarding the emission standards for nitrogen oxides.

d,January 1, 2022Chinese-flagged domestic vessels that are built thereafter (based on the date of keel laying) or undergo major modifications, and that enter coastal control areas and inland control areas, with single-cylinder displacement greater than or equal to 30 liters, should comply with the 'International Convention for the Prevention of Pollution from Ships'tier-IIIRegarding the emission standards for nitrogen oxides.

4. In addition, there are requirements for the use of shore power

5. South Korea's Latest Emission Control Zone

Including eight ports in South Korea: Busan, Incheon, Ulsan, Yeosu, Gwangyang, Hadong, Pyeongtaek, and Dangjin; before the end of 2020 was a transition period, with oil change one hour before and after berthing. After 2021, entering the control area requires the use of 0.1% low-sulfur oil.

6. Ports and waters of Iceland;

7. Norway - World Heritage 'Fjord' Area;

8. Turkey - Port

Finally, let's talk about the exhaust gas cleaning system (EGCS)

Exhaust Gas Cleaning Systems (EGCS), as SOx equivalent compliance devices, are used to meet the requirements of the 'Global Sulfur Cap.' The IMO resolution MEPC.259(68) provides detailed regulations on the use of EGCS on ships worldwide. However, in addition to following this regulation, various regions around the world have also introduced specific regional requirements (including scrubber water discharge). We have now compiled the requirements for key countries/regions.

Asia region

China

It is prohibited to discharge wash water from open-loop exhaust gas cleaning systems in port waters within inland control areas, coastal control areas, and the Bohai Sea.

Hong Kong, China

1. Ships using EGCS need to submit a written application for initial or subsequent certificate exemption 14 days before arrival at the port. The Hong Kong Environmental Protection Department will issue an exemption of no more than 3 years after being satisfied with the review of the relevant documents.

2. If a vessel uses non-compliant fuel, an exemption for one stay period in Hong Kong may be granted with the consent of the Hong Kong Environmental Protection Department.

Taiwan, China

If the provisions of MEPC.259(68) are met, the exhaust gas cleaning system (EGCS) may be accepted as an equivalent alternative method.

Australia

Restricted discharge of wash water

The discharge of wash water must meet the following requirements:

1. Approval equivalent to that of the flag state's competent authority or its authorized RO is required.

2. Notify AMSA before arriving at the first port in Australia and report as required.

3. Meet the monitoring requirements for the discharge of washing water.

4. Meet the requirements for discharging, handling, and recording EGCS wash water residues onshore.

5. The testing of wash water is carried out through sampling and analysis during the trial operation of the EGCS, and it must be conducted at least once every twelve months over a period of two years. If the data or evidence from this sample analysis is not provided to AMSA before arriving at the first port in Australia, the vessel is not allowed to directly discharge EGCS wash water into Australian waters.

6. If any EGCS system is found not to meet IMO guideline requirements (including but not limited to wash water discharge standards), its use in Australian waters may be prohibited.

Japan / South Korea

According to IMO guidelines, EGCS is accepted as an equivalent alternative method.

Singapore

1. Starting from January 1, 2020, the discharge of wash water is prohibited (this ban does not apply to vessels navigating in Traffic Separation Schemes (TSS) and not docking at Singapore ports).

2. For ships flying the Singapore flag, the emission reduction technologies installed on the ship must be approved by the MPA (submitted to MPA through RO).

Europe region

European Union

1. Unless a closed-loop EGCS is used, fuels with a sulfur content exceeding 3.5% shall not be used.

2. For ships flying the flag of an EU member state, the EGCS should be approved in accordance with the requirements of the Marine Equipment Directive (MED) 2014/90/EU.

3. For EGCS based on research and experimental purposes, the European Union has proposed requirements for related reports, duration, emissions, and evaluation.

4. For EGCS that use chemical agents, additives, formulations, or generate related chemical agents within the system, wash water shall not be discharged into the ocean—including enclosed docks, ports, and estuaries—unless the shipowner can demonstrate that its discharge has no significant negative impact and does not pose a threat to human health and the environment. If NaOH is used, the wash water may be discharged if it meets the IMO EGCS guideline discharge standards and its pH does not exceed 8.0.

5. For ships navigating EU waters, it is required to install EGCS for continuous monitoring of SOx emissions, which means that equipment approved under Scheme A is not suitable for use unless it has a redundant exhaust gas continuous monitoring (SO2/CO2) system.

The EU directive (Directive 2012/33/EU) allows the use of EGCS as an alternative measure to meet SOx emission control requirements, but it should operate in closed mode (Article 3a). Therefore, ships equipped with open-type EGCS should switch to compliant fuel and stop using the EGCS before entering waters regulated by the EU directive; ships equipped with hybrid EGCS should switch to closed mode operation before entering waters regulated by the EU directive. Relevant fuel changes or EGCS operating mode changes should be recorded as required.

Prohibit discharge of washing water

The following countries prohibit the discharge of wash water:

Germany, Belgium, Latvia, Estonia, Lithuania, Ireland

The Americas

United States

Differences from the IMO requirements:

1. The discharge of wash water shall not contain oil, including oily mixtures, the harmful quantity of which is determined according to 40 CFR Part 110.

2. Discharging wash water residues is prohibited; they must be sent to onshore reception facilities.

3. Special provisions for the use of EGCS:

3.1 The continuous monitoring equipment for wash water must be regularly calibrated in accordance with the requirements of the testing equipment manufacturer and the EGCS manufacturer.

3.2 The monitoring equipment for PAH (polycyclic aromatic hydrocarbons) emissions shall have a service life of at least 2 years.

3.3 Regulations on EGCS wash water discharge:

1) The pH value measured at the ship's overboard discharge outlet shall not be less than 6.0. No other pH measurement methods are accepted. As an exception during ship operation and conversion, the maximum allowable difference in pH values between the inlet and outlet is 2.0 pH units. This difference must be measured at the ship's inlet and overboard discharge locations.

2) Beyond three nautical miles from the shore, the USCG may adopt a case-by-case approach and accept IMO's provisions on wash water discharge values and measurement methods (i.e., direct measurement or measurement using calculation methods).

3) During the first year of permit coverage or system operation (whichever comes first), two samples of each component group required for analysis in 4) must be collected and analyzed to demonstrate the maintenance of treatment equipment, the accuracy of probes, and compliance with permit requirements. Samples must not be taken less than 14 days apart. Samples must be collected at the water intake (as background), water after it flows through the scrubber (but before any treatment system), and at the discharge point. After the first year, at least one sample must be collected each calendar year. Records of sampling and test results must be kept on board for 3 years.

4) The projects mentioned in 3) that need analysis are as follows: a. Dissolvable metals and total metals: As, Cd, Cr, Cu, Pb, Ni, Se, Ti, V, Zn (EPA Method 200.8 or 200.9 is recommended); b. PAHs (polycyclic aromatic hydrocarbons) (EPA Methods 550.1, 610, 625, 8100, 8270c, 8310 are recommended); c. Nitrates and nitrites (EPA Method 353.2 is recommended); d. pH value (using Standard Method (SM) 4500-H B).

California CARB regulations (13 CCR, section 2299.2) do not allow the use of EGCS as an alternative method for SOx emission control (temporary exemptions are only granted for experimental and research-stage emission reduction technologies/methods). For vessels equipped with EGCS, they should switch to compliant MGO or MDO in a timely manner before entering waters regulated by CARB (within 24 nautical miles from the coast) and stop using EGCS. The related switching operations should be recorded in accordance with regulations.
