Jotun's Hull Skating Solutions Receives DNV Verification Maritime Activity Reports, Inc. May 21, 2026 © Jotun/Jotun Hull Skating Solutions Jotun's Hull Skating Solutions (HSS) has received independent verifications from DNV, confirming that vessels maintained clean hulls, with no measurable speed loss during the period reviewed. The independent verification confirms no measurable speed loss and an always clean hull under real operating conditions. Based on a combined assessment of physical in-water inspections and verified performance monitoring in line with ISO 19030, the verification confirms that hulls protected with HSS remain effectively free from fouling throughout the observation period. The verification represents a milestone for hull performance management, providing independent, third-party confirmation that continuous hull cleanliness can be achieved and sustained in operation, and that this cleanliness translates directly into maintained vessel speed. The verification is grounded in physical inspection data from in-water inspections carried out across a sample of 33 vessels. These inspections consistently confirmed the absence of fouling, providing direct evidence that the hulls remained in a clean condition throughout the assessed period. In parallel with the physical inspections, DNV assessed performance monitoring data from 12 vessels operating under HSS. The analysis showed no measurable speed loss, using an average of 3.5 years of in-service data, including a one-year reference period as per ISO 19030. This confirms that the verified clean hull condition is not only visible through inspections but also reflected in vessel performance data. HSS is Jotun's proactive hull cleaning solution designed to prevent fouling from developing in the first place. "Using the robotic HullSkater to inspect and proactively clean the underwater hull, early-stage fouling is removed before it can attach and grow, and that keeps the hull in a clean condition while the ve
