EGCSA provides open access to reference material that may be useful to all those interested in exhaust gas cleaning systems. This includes guides to promote standards. EGCSA also undertakes and sponsors research work linked to sulphur in marine fuels and associated emissions. These reference papers and studies are available to download below.
Note: The latest IMO publications including all MARPOL regulations can be obtained as e-books from distributors listed at IMO publications – https://www.imo.org/en/publications/Pages/Default.aspx
Ecotoxicity testing and risk assessment of wash water from open loop scrubbers
Independent report by DHI A/S using IMO GESAMP methodology presents a risk assessment based on a series of ecotoxicological studies of a composite sample from four different open loop scrubbers discharging into port and shipping lane scenarios.
The report concludes that the RCR (Risk Characterization Ratio) is below 1, which means that the risk of open loop scrubber discharges into the aquatic environment can be considered acceptable.

Guidance on indication of ongoing compliance in the case of the failure of a single monitoring instrument, and recommended actions to take if the Exhaust Gas Cleaning Systemn(EGCS) fails to meet the provisions of the 2015 EGCS Guidelines (resolution MEPC.259(68))

Study report on analyses of water samples from exhaust gas cleaning systems
This document provides the results of a sampling campaign of washwater from exhaust gas cleaning systems on a series of ships and the subsequent analysis performed jointly by EGCSA and Euroshore (the association representing port waste reception facility providers).
The study confirms the very low levels of materials of interest entering the sea in water from exhaust gas cleaning.

Effects of Sea Water Scrubbing
BP Marine in co-operation with P&O Ferries installed a flue gas scrubber system into the channel ferry “Pride of Kent”, operating between Dover (UK) and Calais (France). This report by Terramare Research Centre, Germany and the University of Newcastle, UK details the analysis of the overboard discharges and their influence on the marine environment, especially that of the ports.
Scrubber payback scenarios
Complete the grey boxes in this useful spreadsheet from Langh Tech to illustrate scrubber payback periods.
The spreadsheet allows three scenarios to be developed based on a range of HFO, 0.5% LSFO and 0.1% MGO prices entered by the user. Entering ship engine data and the vessel’s operating profile provides scrubber running costs (OPEX) based on fuel consumption and sulphur content. Entering component and installation costs, provides repayment times for the scrubber investment. Repayment is based on the price gap between HFO and low sulphur fuels.
EGCSA Handbook 2012
The EGCSA Handbook 2012 is now freely available to view as a flip book and to print
- An overview of air pollution mechanisms related to ship emissions
- The background to ship emission regulations and guidelines
- How compliance is acheived using Exhaust Gas Cleaning Systems
- EGCS technologies and treatment processes for SOx, NOx and particulate matter emissions
The EGCSA Handbook refers to 2009 Guidelines for Exhaust Gas Cleaning System MEPC.184(59), now superceded by 2015 Guidelines for Exhaust Gas Cleaning System MEPC.259(68), which are available as part of MARPOL Annex VI from IMO publications.
Section 7 and Appendix I regarding scrubber vendors have also been superceded and EGCSA members should be contacted directly for details of their Exhaust Gas Cleaning Systems.
This is a large publication and the time for the print facility to become fully enabled will depend on the speed of internet connection.
An A5 sized version of the Handbook (2 pages on each A4 page) in pdf format can be downloaded here
EGCSA Guide – Scrubber Water Sampling Point Specification
This Guide aims to facilitate the taking of water samples for consistent laboratory analysis and reporting of the quality of overboard discharges by providing a standard for scrubber system sampling points
- The configuration of a simple manual valve arrangement to obtain representative samples from the centre line of a pipe.
- Where the sampling points should be positioned in open, closed and hybrid scrubber systems
- How the sampling points should be orientated on pipework
- Other considerations for safe, convenient and uniform sampling
The Guide is free to download.

Ship Guide – Scrubber Water Sample Analysis Programme
In partnership with Euroshore, EGCSA has undertaken 2 scrubber water analysis programmes for the European Sustainable Shipping Forum (ESSF).
Based on the experience of sailing with vessels to take samples for the first programme, EGCSA has produced a practical guide to scrubber water sampling for ship staff, which has been used during the second programme.
The Ship Guide is freely available to download and use as a model for other scrubber water sample analysis programmes. It is focussed on taking samples for analysis of EPA 16 priority PAHs (polycyclic aromatic hydrocarbons) and selected total metals. This version is non laboratory specific.
