Norwegian coatings manufacturer Jotun has introduced HullKeeper, a proactive hull optimisation programme, developed through extensive research and testing.

HullKeeper combines Jotun’s digital capabilities, ROV inspections and analytical and technical expertise to help operators keep fuel, inspection and cleaning costs under control. The four-part programme optimises hull performance, regardless of the chosen coating. Ship operators are said to be able to take full control of their operations through hull monitoring, fouling risk alerts, inspections and advisory services. Operators can benefit from the complete package or select only the parts that work for them.

HullKeeper is grounded in Jotun’s proprietary fouling risk algorithm, supported by data from different sources to make fouling control and efficiency more predictable. By providing insight into issues before they occur, ship operators can take planned corrective actions. And as more data and information accumulate, best practices can be identified and implemented across the whole fleet.

Stein Kjølberg, Jotun Global Category Director Hull Performance, said: “Jotun has a proven record of developing products and services that help customers meet the demands of a changing industry. HullKeeper extends the range of our services, helping operators make well-informed and proactive decisions to improve hull efficiency as they push for optimal performance, efficiency and regulatory compliance.”

Jotun’s Global Digital and Data Director, Andreas Krapp, said: “HullKeeper is a market differentiator in the sense that it offers unique support that both adds value and meets the needs of customers. Ship operators that use HullKeeper will be able to identify potential problems long before fouling impacts vessel speed, allowing them to make better decisions, faster.”     

Krapp explains that increased fuel consumption related to biofouling accounts for about 9% of the 919m tons of CO₂ and 21m tons of other greenhouse gases (GHG) emitted by shipping annually. While he acknowledges that it is unlikely that the industry will reach the full potential reduction of 85m tons of GHGs, HullKeeper represents a genuine opportunity to help the industry make significant emissions reductions. He said: “In addition to offering ship operators a cost-effective programme that can reduce GHG emissions, HullKeeper helps them save on bunkering costs. In this way, HullKeeper incentivises improved environmental performance.”
