ISO 19030 Enables Quantified Hull Performance Monitoring

Legend of the Seas in Drydock

The recently published ISO 19030 defines standards for the measurement of changes in hull and propeller performance.

Explained Stein Kjølberg, global sales director of hull performance solutions, Jotun Performance Coatings: “The ISO 19030 offers a transparent way of measuring everything that affects the hull and propeller performance.

“Although it is not a method to measure paint quality, it will give a very good indication of the performance level of various types of antifouling.

“The basic concept is to define how much more or less speed is achieved at a given power, and that is expressed as an average speed loss over time. Sensors are installed to measure speed, draft, trim, torque, rpm, wind and more, reporting at a high frequency, on the average every 15 seconds.”

According to a statement from Jotun, the standard will enable users to quantify how different hull solutions are contributing, including antifouling coatings, providing accountability to shipowners.

The standard offers a two-tier methodological approach: ISO 19030-2, the default measurement method said to have the greatest accuracy; and ISO 19030-3, allowing for alternative methods in order to increase the applicability of the standard.

Jotun said the move has the potential to reduce industry green house gas emissions by 10 percent, while saving operators up to $30 billion in annual energy costs, by enabling better hull and propeller performance.
