Ridgebury Tankers completes tanker emissions reduction analysis project

Ridgebury Tankers has completed an emissions reduction validation project to assess improvements in vessel performance for its Suezmax tanker, Ridgebury John Zipser, following a retrofit in 2019, designed to evaluate return on an investment in scrubbers as well as accrued carbon savings.

The vessel operator worked with technology company FuelTrust on the project, using its AI system to establish a carbon baseline for the tanker by assessing fuel and operations data from previous years, comparing month-by-month and year-by-year performance to measure improvements.

The system calculated the entire emissions stack of the vessel, including CO2, NOx, SOx, CAP and HAP, to analyse the effects on vessel performance of installing a scrubber, a silicone hull coating, and buying higher quality fuels.

FuelTrust’s system traces links between fuel bunkers at source, through combustion and subsequent emissions, analysing the chemical interactions that take place during onboard combustion to provide accurate reporting. AI-based virtual models of engines, scrubbers, coatings, and other clean technologies are then used to analyse impacts on ship performance, allowing each option to be ‘switched on or off’ to observe outcomes.

“Our commitment to operating a sustainable business means that when we add a tanker to our fleet of vessels, we first consider how our investment will benefit the environment,” said Robert Burke, CEO at Ridgebury.

“Working with FuelTrust gives a higher level of detail and accuracy about how our investments affect emissions in any scenario. For the benefit of our seafarers, our investors, and the environment, we can use this insight to deliver measurable improvements to our vessels.”

Ridgebury is now working with FuelTrust to analyse additional tankers, with FuelTrust set to produce an analysis of the relative financial and environmental benefits that could be accrued through the installation and effective operation of scrubbers, as well as insight into optimal HFO outcomes versus continued use of VLSFO without retrofit.
