Jotun Hull Performance Solutions (HPS) launched the HPS Newbuilding Solution at Kormarine in Busan, South Korea. The HPS Newbuilding Solution is aimed at yards delivering vessels with eco-design and who want to maximise the energy efficiency at both speed trial and in operation.
“With HPS Newbuilding Solution Jotun enables yards to become more competitive when bidding for eco-ship projects. The solution provides an opportunity to both optimise initial performance as well as lifetime performance. The solution thereby serves the long term interests of the designers, yards, owners, operators and the environment,” says Mr Geir Boe, Vice President Jotun Marine Coatings.
The foundation of the HPS Newbuilding Solution is SeaQuantum X200, Jotun’s top of the line antifouling with documented low friction properties, designed to maximise initial and lifetime performance. In addition comes 3 upgrade components with reliable guarantees.
Roughness of the hull has a major impact at speed trial. The first component of the HPS Newbuilding Solution is a Smooth Application Package that combines comprehensive technical service with an optimised anticorrosive system. Jotun measures average roughness on the underwater hull surface and offers a money-back guarantee as a part of its Smooth Application Package.
Keeping the hull slime and fouling free through the outfitting period is a challenge. Jotun’s second component is an Outfitting Protection Package which includes a final coat of the newly developed SeaQuantum X200-S which has superior resistance to slime and fouling. Any fouling incurred over the docking may have a major impact on the attained Energy Efficiency Design Index (EEDI). With the Outfitting Protection Package Jotun guarantees a clean hull at speed trial. Yards will then avoid costly re-dock or under water hull cleaning which is time consuming and may increase hull roughness.
The third and last component is a 60 month high performance guarantee with cash back if average speed loss exceeds 1.5% over 60 months which may be transferred from the yard to the owner. This equals a 15% improvement in propulsion efficiency over 60 months compared to market average performance. This component gives the yards an opportunity to differentiate themselves by extending from a typical 12 months standard guarantee to a 60 month high performance cash back guarantee.
By analysing a series of accurate measurements from the ship in voyage, Jotun determines the condition on the underwater hull and its effect on fuel consumption using the Jotun Hull Performance Measurement Method.
