Jotun’s SeaQuantum X200 Antifouling Achieves Speed Loss Verification from DNV

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
