CSA 2020 flags ‘crucial’ role of scrubbers during IMO 2020 transition

The Clean Shipping Alliance 2020’s (CSA 2020) Executive Director, Poul Woodall, says ‘timely’ installation of scrubbers contributed to shipping industry’s ‘smooth transition’ to the IMO 2020 era.

Around 4,000 ships are estimated to be fitted with exhaust gas cleaning systems (EGCS) which enabled those ships to continue to burn fuel with a sulphur content above 0.50%.

Woodall said that in addition to achieving ‘much lower’ sulphur (SOx) reductions than required by IMO2020, and reductions of other pollutants as well, there are added advantages of EGCS in minimising ships’ carbon footprint.

Woodall said: ‘On a well-to-wake basis, EGCS-fitted vessels have a lower CO2 footprint than the most widely-used alternative fuel options of MGO and VLSFO.’

Woodall also pointed to a CE Delft study comparing the CO2 emissions of MARPOL Annex VI compliance options in 2020.

The study ‘found the increase in CO2 footprint from the additional refining of MGO to likely be in the range of 10-15% and potentially as high as 25%,’ said Woodall. ‘In contrast, the increased CO2 from EGCS is only in the range of 1.0-1.5%.’

Woodall continued: ‘Therefore, there should be broader awareness that EGCS-fitted vessels show a significantly better CO2 performance than similar vessels using refined fuels for compliance, such as MGO/VLSFO. This supports the current ambitions of significantly lowering CO2 emissions by 2030.’

As previously reported, last week, the International Maritime Organization said the transition to IMO 2020 had been ‘extremely smooth’ with a total of 55 cases of very low sulphur fuel oil (VLSFO) non-availability reported throughout the year.
