Introduction to Global Sulphur Emission Control Areas

2021-11-03Views:1515

Many friends have reported that a lack of understanding of the latest global emission control areas and the latest emission policies easily leads to vessels being fined or detained by local PSCOs. In this issue, we have endeavored to collect and compile the latest information on the scope and emission requirements of emission control areas around the world and present it to you all.

International Ship & Offshore Media, which is preparing for the 5th Shanghai 2020 Summit on Ship Ballast Water Management Systems (BWMS) and Scrubbers to be held on December 2-3, has learned that.

What are ship emission control areas for?

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

II

Why control air pollutants from ship emissions?

Relevant studies show that air pollutants from ship emissions mainly come from exhaust gases generated by ship power systems, volatilization of transported cargo, onboard incineration, etc. The air pollutants generated are mainly sulfur dioxide (SO2) and nitrogen oxides (NOx), and also contain a certain amount of inhalable particulate matter (PM10), fine particulate matter (PM2.5), carbon monoxide (CO), volatile organic compounds (VOCs) and other air pollutants, as well as greenhouse gases mainly consisting of carbon dioxide (CO2). At present, domestic and international research on the prevention and control of ship air pollution mainly focuses on SO2, NOx and PM. Among them, SO2 is converted from sulfur in ship fuel, so SO2 emissions are directly related to factors such as fuel type, fuel quality and consumption; NOx is mainly produced by the oxidation of nitrogen in the air during rapid combustion and high-pressure processes, and its emissions are closely related to the engine and its operating conditions; particulate pollutants such as PM10 and PM2.5 include primary particulate matter such as directly emitted black carbon and heavy metals, as well as secondary particulate matter such as sulfates, nitrates and secondary organic matter formed through chemical reactions, and SOx and NOx can all be converted into particulate matter. Controlling the sulfur content of ship fuel is an effective means of reducing sulfur oxide and particulate matter emissions during ship engine operation, and is also the main control method currently adopted domestically and internationally for ship air pollution.

III

What ship emission control areas are there?

After extensive research, the editor has found that there are currently 6 internationally recognized emission control areas, and in addition, China, South Korea, Norway, Iceland, Turkey and other countries have all issued corresponding emission control areas and emission standards. The 6 most important ones include:

Established with the approval of the International Maritime Organization:

Baltic Sea area

North Sea area

North American area

Caribbean Sea Emission Control Area

Established with the approval of the European Union:

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

IV. China's latest emission control areas

On December 20, 2018, China's Ministry of Transport issued the Implementation Plan for Ship Air Pollutant Emission Control Areas, specifying the scope and control requirements as follows:

I. Emission control areas:

Building on the existing ship emission control areas in the Bohai Rim (Beijing–Tianjin–Hebei), Yangtze River Delta and Pearl River Delta waters, China further expanded their geographical scope to include coastal and inland river control areas.

China's coastal and inland river control areas are shown on the left, and the Hainan control area is shown on the right:

China's inland river control areas

II. Requirements for controlling sulfur oxide emissions from ships:

1. From January 1, 2019, all ships entering the coastal control area must use marine fuel with a sulfur content not exceeding 0.5% m/m.

2. From January 1, 2020, seagoing ships entering inland river emission control areas must use marine fuel oil with a sulfur content not exceeding 0.1% m/m.

3. From January 1, 2022, ships entering the Hainan control area must use ultra-low-sulfur fuel with a sulfur content of 0.1% m/m.

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

III. Provisions have also been made for nitrogen oxide emissions:

a. January 1, 2000 or later is the construction date (based on keel laying) or the date of major conversion applicable to ships on international voyages with individual engine power exceeding 130 kW; these ships must meet the tier-I nitrogen oxide emission standards under the International Convention for the Prevention of Pollution from Ships.

b. January 1, 2011 or later is the construction date (based on keel laying) or the date of major conversion applicable to ships on international voyages with individual engine power exceeding 130 kW; these ships must meet the tier-II nitrogen oxide emission standards under the International Convention for the Prevention of Pollution from Ships.

c. March 1, 2015 or later is the construction date (based on keel laying) or the date of major conversion applicable to Chinese-flagged ships on domestic voyages with individual engine power exceeding 130 kW; these ships must meet the tier-II nitrogen oxide emission standards under the International Convention for the Prevention of Pollution from Ships.

d. January 1, 2022 or later is the construction date (based on keel laying) or the date of major conversion applicable to Chinese-flagged ships on domestic voyages entering the coastal and inland river control areas. Ships with a displacement of 30 liters or more per cylinder must meet the tier-III nitrogen oxide emission standards under the International Convention for the Prevention of Pollution from Ships.

IV. There are also requirements for the use of shore power

V. South Korea's latest emission control areas

These include eight South Korean ports: Busan, Incheon, Ulsan, Yeosu, Gwangyang, Hadong, Pyeongtaek and Dangjin. The period before the end of 2020 was a transition period, with fuel changeover one hour before and after berthing. From 2021 onward, ships entering these control areas must use low-sulfur fuel with a sulfur content of 0.1%.

VI. Iceland's ports and waters;

VII. Norway's World Heritage fjord areas;

VIII. Ports in Turkey

Finally, a look at exhaust gas cleaning systems (EGCS)

Exhaust gas cleaning systems (EGCS) are SOx-equivalent compliance systems used to meet the global sulfur cap. IMO resolution MEPC.259(68) sets out detailed provisions for the use of EGCS on ships worldwide. In addition to following these provisions, regions around the world have introduced specific regional requirements, including those for washwater discharge. The requirements of key countries and regions are summarized below.

Asia

China

Discharging washwater from open-loop exhaust gas cleaning systems is prohibited in port waters within inland waterway control areas and coastal control areas, and in the waters of the Bohai Sea.

Hong Kong, China

1. For a ship using an EGCS, a written application for the initial or subsequent exemption certificate must be submitted 14 days before arrival at port; after satisfactory review of the relevant documents, the Hong Kong Environmental Protection Department will issue an exemption valid for no more than 3 years.

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

Taiwan, China

Exhaust gas cleaning systems (EGCS) are accepted as an equivalent alternative method if the provisions of MEPC.259(68) are met.

Australia

Restricted discharge of washwater

Discharging washwater requires meeting the following requirements:

1. Equivalent approval from the flag State administration 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 washwater discharge.

4. Meet the requirements for shore disposal, treatment and recording of EGCS washwater residues.

5. Washwater testing is sampling analysis during EGCS commissioning, and must be carried out once every twelve months for at least two years. If the data or evidence from this sampling water analysis is not provided to AMSA before arriving at the first port in Australia, the ship is not permitted to discharge EGCS washwater directly into Australian waters.

6. If any EGCS is found not to meet the requirements of the IMO guidelines (including but not limited to washwater discharge standards), use of the EGCS in Australian waters may be prohibited.

Japan / South Korea

EGCS is accepted as an equivalent alternative method in accordance with the relevant IMO guidelines.

Singapore

1. Discharge of wash water is prohibited from January 1, 2020 (this prohibition does not apply to ships in traffic separation schemes (TSS) that do not berth in the Port of Singapore).

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

European Region

European Union

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

2. For ships flying the flag of an EU Member State, the EGCS shall be approved in accordance with the requirements of DIRECTIVE 2014/90/EU for marine equipment (MED).

3. For EGCS based on research and testing purposes, the EU has set out requirements for reporting, duration, emissions and assessment.

4. For EGCS using chemical agents, additives, formulations and related chemical agents generated within the system, unless the shipping company demonstrates that the discharge of its wash water has no significant negative effects and does not pose a threat to human health and the environment, the wash water shall not be discharged into the sea, including enclosed docks, ports and estuaries. If NaOH is used, the wash water may be discharged if it meets the discharge standards of the IMO EGCS Guidelines and its pH value does not exceed 8.0.

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

EU Directive (Directive 2012/33/EU) allows the use of EGCS as an alternative measure to SOx emission control requirements, but it shall be operated in closed mode (Article 3a). Therefore, for ships equipped with open-type EGCS, they shall promptly switch to compliant fuel oil and stop the EGCS before entering waters specified in the EU Directive; and for ships equipped with hybrid EGCS, they shall promptly switch to closed mode operation before entering waters specified in the EU Directive. The relevant fuel oil changeover or EGCS operating mode changeover shall be recorded as required.

Prohibition of Wash Water Discharge

The following countries prohibit wash water discharge:

Germany, Belgium, Latvia, Estonia, Lithuania, Ireland

Americas Region

United States

Differences from IMO requirements:

1. The discharge of wash water shall not contain oil, including oily mixtures, in harmful quantities as determined under 40 CFR Part 110.

2. Discharge of wash water residues is prohibited; they must be delivered to shore reception facilities.

3. Special provisions for the use of EGCS:

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

3.2 Monitoring equipment for PAH (polycyclic aromatic hydrocarbons) emissions shall have a durability of at least 2 years.

3.3 Provisions for EGCS wash water discharge:

1) The pH value measured at the ship's overboard discharge outlet shall not be less than 6.0; other pH measurement methods are not accepted. As an exception during ship maneuvering and changeover, a maximum difference of 2.0 pH units between inlet and outlet is allowed; this difference must be measured at the ship's inlet and overboard discharge locations.

2) Beyond 3 nautical miles from shore, the USCG may adopt a case-by-case approach and accept the IMO provisions for wash water discharge values and measurement methods (i.e., direct measurement or calculated measurement).

3) Two samples of each component required to be analyzed in 4) below must be collected and analyzed during the first year of permit coverage or system operation, whichever is earlier, to demonstrate the maintenance of the treatment equipment, the accuracy of the probes and compliance with the permit requirements. Samples shall not be collected within 14 days of each other. Samples must be collected at the inlet water (as background), the water after passing through the scrubber (but before any treatment system), and the discharge water. After the first year, samples must be collected at least once each calendar year. Records of sampling and testing results must be retained on board for 3 years.

4) The items required to be analyzed mentioned in 3) above are as follows: a. Dissolved metals and total metals: As, Cd, Cr, Cu, Pb, Ni, Se, Ti, V, Zn (EPA Method 200.8 or 200.9 recommended); b. PAHs (polycyclic aromatic hydrocarbons) (EPA Method 550.1, 610, 625, 8100, 8270c, 8310 recommended); c. Nitrate and nitrite (EPA Method 353.2 recommended); d. pH value (Standard Method (SM) 4500-H B).

The California CARB regulation (13 CCR, section 2299.2) does not allow the use of EGCS as an alternative method for SOx emission control (temporary exemptions are granted only for emission reduction technologies/methods in the experimental and research stages). For ships equipped with EGCS, they shall promptly switch to compliant MGO or MDO and stop the EGCS before entering waters specified in the CARB regulation (within 24 nautical miles of the coast), and the relevant changeover operations shall be recorded as required.
