Jotun’s SeaQuantum X200 antifouling has received official verification from DNV confirming an average speed loss of just 1.0% over a dock-to-dock period.
This is believed to represent the lowest verified speed loss in the industry, setting a new benchmark for hull performance.
Habibe Escobar, Category Manager for the SeaQuantum brand, said: “SeaQuantum X200 is Jotun’s flagship SeaQuantum antifouling, and part of HPS 2.0. It has 15 years track record of maximising 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 is based on the in-service performance methodology outlined in ISO 19030, which evaluates speed loss over the last four years of a five-year dry-docking cycle, with the first year out of dock establishing a benchmark.
Morten Sten Johansen, Global Category Director, Hull Performance, Jotun, added: “We are pleased to receive this verification from DNV, which confirms what our data has consistently shown. As the Home of hull performance, we are happy to bring in another evidence of our efforts.”
The data used in the verification includes 41 vessels coated with SeaQuantum X200, representing a fleet of medium- to high-activity vessels operating under normal conditions. The verified speed loss of 1.0% showed a contrast to the industry benchmark with a baseline of 5.9% average speed loss as per ISO 19030.
Olav Rognebakke, Head of Section Hydrodynamics and Stability, DNV Maritime Advisory, said: “The verification of SeaQuantum X200’s performance was carried out with rigour and precision, enabled by access to high-quality performance data. Based on our evaluation, the coating demonstrated the lowest average speed loss verified under ISO 19030 standards. This level of performance is consistent with reduced hull resistance over time, which can contribute to lower fuel consumption under typical operating conditions.”
This gap between 1.0% speed loss and the industry benchmark translates into substantial fuel savings and reduced CO₂ emissions:
- The market average performance has an average speed loss of 5.9%, based on ISO 19030.
- This translates to 17.7% drop in hydrodynamic efficiency using the industry standard speed loss ratio of 3:1.
- Thus, a 1.0% speed loss corresponds to just 3% drop in hydrodynamic efficiency.
- This results in a substantial gap in hydrodynamic efficiency when comparing SeaQuantum X200 and the industry baseline and reflects the reduction of fuel usage of 14.7% enabled by SeaQuantum X200.
Johansen said: “Simply put, to compensate for 1% loss in speed, a power increase of 3% is required. The difference between 1% speed loss and 5.9% speed loss is therefore huge both in terms of preserving fuel and when cutting carbon emissions.”
When launched in 2011, Jotun’s Hull Performance Solutions (HPS) is considered to have shifted the focus from promised to proven performance. Jotun continue to deliver premium products and services as part of the enhanced HPS 2.0 tailored to customers’ needs. Jotun continuously focuses on its clean shipping commitment, ensuring quantifiable hull performance for the whole shipping industry. This was quantified earlier in 2025, when DNV verified a saving of 11.1m tons CO₂e for all Jotun coated vessels in 2024 alone, equivalent to fuel worth approximately US$ 2bn.
Johansen concluded: “These verifications reinforce our commitment to deliver real and measurable value to our customers, both in terms of avoided emissions and preserved fuel.”
