DNV Study Suggests Possibility of Eliminating Efficiency Loss From Fouling

A DNV study of 12 vessels using Jotun's proprietary hull-cleaning robot over more than three years found no measurable speed loss over time compared to an initial one-year reference period. The analysis confirmed that hulls remained clean throughout the review period, suggesting that with frequent cleanings, ships can operate with continuously clean hulls and maintain efficiency levels comparable to the day they left drydock.
