Hull coating system for eco-friendly newbuildings

The system is based on Jotun Marine Coatings’ SeaQuantum X200, a low-friction antifouling claimed to maximise initial and lifetime performance, with three add-on upgrade components. These comprise a ‘smooth application pack’ to achieve low roughness at speed trial stage, technical service and optimised anti-corrosion; an ‘outfitting protection package’ to ensure a clean fouling-free hull on sea trials; and a 60-month performance guarantee offering cash back if average speed loss exceeds 1.5% over this five-year period.

The smooth application package comes with a money-back guarantee, while the outfitting protection package, based on a final coat of the newly developed SeaQuantum X200-S, said to offer superior resistance to slime and fouling. With this package Jotun guarantees a clean hull at speed trial, meaning that yards will then avoid costly re-dock or under water hull cleaning which is time consuming and may increase hull roughness.

The 60 month high performance guarantee offers a cash back guarantee, transferrable from yard to owner, if average speed loss exceeds 1.50% over the five year period. This is said to be equivalent to a 15% improvement in propulsion efficiency over 60 months compared to market average performance. This enables yards to extend the typical 12 months standard guarantee period to a 60 month high performance cash back guarantee.

By analysing a series of measurements from the ship in service, Jotun’s hull performabnce measurement method can determine the condition on the underwater hull and its effect on fuel consumption.

“With HPS Newbuilding Solution Jotun enables yards to become more competitive when bidding for eco-ship projects. The solution provides an opportunity to both optimize initial performance as well as lifetime performance. The solution thereby serves the long term interests of the designers, yards, owners, operators and the environment,” said Geir Boe, vice president Jotun Marine Coatings.
