Jotun’s SeaQuantum X200 coating has achieved an industry first. Verified by DNV at just 1% average speed loss, the coating marks a major gain for efficiency and lower emissions in global shipping.
When it comes to decarbonising shipping, every percentage point counts. Norwegian coatings manufacturer Jotun has announced that its antifouling system, SeaQuantum X200, has been verified by DNV for an average speed loss of only 1% over a full docking cycle.
The result, confirmed under the ISO 19030 performance standard, represents the lowest verified speed loss in the industry. According to DNV, this performance is “consistent with reduced hull resistance over time, which can contribute to lower fuel consumption under typical operating conditions,” said Olav Rognebakke, Head of Section Hydrodynamics & Stability in DNV Maritime Advisory.
“SeaQuantum X200 is Jotun’s flagship SeaQuantum antifouling, and part of HPS 2.0,” said Habibe Escobar, Category Manager responsible for Jotun’s SeaQuantum brand. “It has 15 years track record of maximizing hull performance with around 2,500 deep-seagoing vessel applications, and delivers high performance for predictable trades, which is now also quantified and confirmed by DNV. An average speed loss of 1.0% really pushes the boundaries of what an antifouling can deliver.”
The verification was based on data from 41 vessels coated with SeaQuantum X200, covering a fleet of medium- to high-activity ships operating under normal conditions. The 1% speed loss stands in stark contrast to the industry benchmark of 5.9%, which corresponds to a 17.7% drop in hydrodynamic efficiency.
“Simply put, to compensate for 1% loss in speed, a power increase of 3% is required,” said Morten Sten Johansen, Global Category Director for Hull Performance at Jotun. “The difference between 1% speed loss and 5. % speed loss is therefore huge both in terms of preserving fuel and when cutting carbon emissions.”
That difference translates to roughly a 14.7% reduction in fuel use compared with the market average, a saving that extends far beyond economics.
Earlier this year, DNV also verified that Jotun coatings helped vessels avoid 11.1 million tons of CO₂ emissions in 2024, equivalent to about 2 billion dollars in saved fuel.
“These verifications reinforce our commitment to deliver real and measurable value to our customers, both in terms of avoided emissions and preserved fuel,” said Johansen.
