Jotun Reveals Hull Cleaning Technology

FRIDAY, APRIL 24, 2020

Recently, Norwegian paints and coatings manufacturer Jotun (Sandefjord, Norway) announced the launch of Hull Skating Solutions (HSS), a proactive cleaning solution for the maritime industry.

According to the company’s press release, the HSS offers high performance antifouling, proactive condition monitoring, inspection and proactive cleaning, high end technical service, and performance and service level guarantees.

“Bio-fouling is a big challenge for the shipping industry,” said Geir Axel Oftedahl, Business Development Director of Jotun. “It increases frictional resistance leading to speed loss and greater fuel consumption, while at the same time increasing the risk of the transfer of aquatic invasive species. It is a burden to the industry, and our planet, and demands decisive action.

“That was our starting point in the conception of HSS—a desire to create a definitive solution to this pressing issue, one that wouldn’t just deal with the problem, but rather prevent it. That is what hull skating achieves.”

Developed over several years, the robotic technology tailors to specific vessels using a proprietary algorithm and big data to accurately predict fouling development and cleaning schedules, reducing both maintenance and fuel costs.

Running on magnetic wheels equipped with electric motors for propulsion and steering, the HSS is comprised of several cameras and sensors, supporting the operator with data for navigation and documenting fouling on the ship hull.

While connected to the operator’s control center through an umbilical or working remotely through 4G coverage, the technology uses a motorized brush which can remove individual bacteria and biofilm  from the hull before macro-fouling can take hold, without causing erosion or damage to the hull coating.

Depending on the size and condition of a vessel, Jotun reports that HSS can complete an inspection and proactive cleaning on a hull within 2-8 hours. Additionally, the company estimates that if all ships in challenging operations converted to HSS, carbon dioxide emissions would be reduced by at least 40 million tons per year.

“We believe this is a landmark development for shipowners worldwide,” Oftedahl adds. “Vessels are often faced with unpredictable operations, with erratic idling periods and varied operational profiles that make the selection of antifouling problematic, even for the best coatings.”
