Shipping urged to prove emissions savings as studies expose prediction gap

Shipping companies are under growing pressure to provide verifiable proof of emissions reductions as new data highlights a persistent gap between predicted and actual performance of energy efficiency technologies.
Recent assessments by classification societies DNV and ABS found that such technologies typically underperform by 20 to 40%, raising concerns about the reliability of current modelling methods. In response, digital solutions provider Oceanly has released findings from its Ecopac energy optimisation system, showing a 60% alignment between forecasted and actual fuel savings.
“As the industry accelerates toward decarbonisation, data-driven proof of performance isn’t optional, it’s essential,” said Oceanly CEO Frederick Lerche-Tornoe. “We’re helping owners move beyond estimates to verifiable outcomes.”
Launched earlier this year, Ecopac uses variable frequency drives to optimise the operation of seawater pumps and engine room fans. In a recent installation aboard a vessel operating in 22 °C waters, the system projected fuel savings of USD 89,000 annually from seawater pumps alone, based on current fuel prices.
Allan Nielsen, CEO of Ecopac developer Danavis Engineering, noted that “when vessels operate in colder waters - below 20–22 °C - savings can exceed 60%.”
The findings come as the industry adjusts to the EU Emissions Trading System, FuelEU Maritime and the IMO’s Carbon Intensity Indicator, which demand clearer evidence of emissions reductions.
