What is Scrubber Exhaust Washwater Testing?

To comply with the IMO’S 2020 Sulphur Cap, scrubbers are being used frequently to remove contaminants from a vessels’ exhausts by spraying a buffer solution (usually seawater) over exhaust gases. A byproduct of these Exhaust Gas Cleaning Systems (EGCS) or scrubbers, is a lot of exhaust Washwater which is discharged overboard. That washwater needs to be tested annually: it can be much more acidic than the surrounding seawater and contains polycyclic aromatic hydrocarbons, particulate matter, nitrates, nitrites, and heavy metals including nickel, lead, copper, and mercury.

Therefore, releasing this water may have toxic impacts on marine life. For this reason, several countries require you to collect this washwater and have it analyzed in a laboratory.

Why you need Scrubber Exhaust Washwater Testing?

Scrubber Exhaust Washwater testing is mandatory prior to calling ports Australian waters (AMSA Marine Notice 5/2019 and 5/2022). In addition, as of June 2022 the IMO MEPC.340(77) regulations apply that require sampling once per year. VGP 2013 also includes testing of Scrubber Washwater water that is discharged.

Scrubber Exhaust Washwater regulations are complex, fragmented and difficult in practice. Many ports or countries restrict the use of scrubbers in their waters, making underway sampling activities complex and potentially risky for ship crews. Moreover, Scrubber Exhaust Washwater testing has to meet specific requirements for you: it should leave full operational flexibility for your crews and vessels.

Still have questions whether or not Scrubber Exhaust Washwater Testing is required for your vessel? Or wonder how to get it done?

GHG Emissions Regulations

EU-MRV
The EU requires Monitoring, Reporting and Verification (EU-MRV) for ships over 5,000 GT (and over 400 GT from 1 January 2025) calling European ports regardless of their Flag, as per EU Regulation 2015/757 and amending Regulation (EU)2023/957. Only Accredited Verifiers independent from the entity providing Monitoring and Reporting, can sign-off on Emissions Reports to be reported in Thetis-EU and included in each ships’ Document of Compliance (DoC).

IMODCS and China-DCS
In  2019 the IMO Data Collection System (IMODCS) became obligatory for vessels above 5,000 GT, to collect fuel use, emissions and ship service information per each vessel’s approved SEEMP II. This regulation is based on MARPOL Annex VI . Recognized Organizations (RO) like Class Societies verify IMODCS reports. The Chinese Maritime Safety Administration started its Data Collection on Energy Consumption (China-DCS): similar but different Emission reporting from any vessel calling specific Chinese ports per regulation from the MSA China Maritime Safety Administration in 2018 (contact us for your copy).

CII  and EEXI
The Carbon Intensity Indicator (CII)  is a system for ships to gradually reduce emissions, that the IMO developed as a mandatory measure under MARPOL Annex VI since 1 January 2023. At that time IMO also implemented its Energy Efficiency Existing Ship Index (EEXI) to rate energy-efficiency of different vessels, which is included in each vessel’s International Air Pollution Prevention (IAPP) Survey by Class.

SEEMP III
From 1 January 2023, ships of 5,000 GT and above must have a verified Ship Energy Efficiency Management Plan (SEEMP Part III) on board to document how their vessel plans to achieve its CII-targets.

UK-MRV
Since  2022, all vessels that are subjected to EU-MRV have to collect data and report emissions per UK-MRV also, for their port calls in the United Kingdom. This is laid down in regulation MIN 669 (M+F) which is likely to be amended in the future.  Verifiers must be UKAS-accredited.

EU-ETS and EUA’s
From 1 January 2024 onwards the EU taxes Emissions from ships through its “cap-and-trade” European Trading System (EU-ETS). Directive (EU) 2023/959 requires vessel owners (or their mandated ISM Company) to purchase and surrender EU Allowances (EUA’s) matching their Emissions that are beyond their yearly allowance.

FuelEU Maritime
As of 2025, the EU is expected to launch its “book-and-claim” FuelEU Maritime Regulation (EU) 2023/1805 which promotes the use of renewable, low-carbon fuels and clean energy technologies for ships – from fuel production wells to ships’ wakes. Fleets of ships should actively lower their GHG intensity of fuels, by 2% in 2025 to 80% in 2050 or pay steep penalties otherwise.
