Jotun has announced that its antifouling solution, SeaQuantum X200, has received official verification from DNV, confirming an average speed loss of just 1.0% over a dock-to-dock period. This represents the lowest verified speed loss in the industry, setting a new benchmark for hull performance.

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.

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% showcase a big contrast to the industry benchmark with a baseline of 5.9% average speed loss as per ISO 19030.

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.
