ISO 19030 ‘Ships and Marine Technology - Measurement of changes in hull and propeller performance’ was finalised in 2016 following three years of development by a wide range of industry stakeholders, including coating and propeller manufacturers, academics, shipowners and data analysts. It enables ship owners and operators to compare hull and propeller solutions, and select the most efficient option for their vessels and fleets.
“ISO 19030 represents a key milestone in on-going work to enhance the accuracy and transparency of hull and propeller performance monitoring,” said Barry Kidd, ISO 19030 working group member for AkzoNobel’s marine coatings business.“However, as a voluntary standard, the success of ISO 19030 is dependent on shipowners and operators understanding and recognising its benefits and applying approved data analysis techniques on board vessels.”
“ISO 19030 has the potential to play a decisive role in strengthening relationships between shipowners and providers of energy saving solutions, such as hull coating and propeller manufacturers, which will in turn enable the industry to work towards the adoption of the most sustainable and efficient technologies.
“However, there is no room for complacency if we want to secure the buy in of shipowners and operators into ISO 19030. It is up to businesses like AkzoNobel to work at the forefront with industry stakeholders to progress its widespread and successful adoption,”he said.
AkzoNobel claimed to have played an influential role in the development of all parts of ISO 19030. In particular, AkzoNobel championed ISO 19030 Part 3, which is founded on a tiered system of potential methods for monitoring, included noon report data collection.
The development of Part 3 ensures that the vast majority of shipowners (90%) can use and demonstrate compliance with the new standard; Part 2 can be used by an estimated 10% of the commercial fleet, as it is based on taking data from sophisticated on board sensors and high frequency intervals.
In addition to measuring actual performance of hull coatings, AkzoNobel has integrated ISO 19030 into its big data hull performance prediction technology Intertrac Vision. This means hull coating performance predictions from Intertrac Vision, can be verified and validated against actual performance using a monitoring process that is ISO 19030 compliant.
The standard was put together by 53 people from all shipping sectors with coatings suppliers, Jotun, IP and Hempel involved with the help of Chugoku and PGG, Stein Kjolberg, Jotun’s global sales director hull performance solutions said at a presentation in London this week.
He explained that the average drop in hull and propeller performance over time caused by bio-fouling and mechanical damage is in the region of 15-20%. This equates to around 9-12% in extra energy costs and greenhouse gas emissions.
Kjolberg said that that for hull coatings manufacturers, the lack of measurability and seeing a return on investment on coatings were the main reasons for the standard being developed.
It consists of three parts - General principles, default method and alternative methods.
He thought that charterers might pay more for a vessel, whose owner/manager could prove that the fouling effect and the coating’s performance was measurable, thus saving them OPEX.
Tobias Groger, DNV GL’s senior consultant performance solutions, said that the standard would be included in the class society’s management platform Eco Insight.
He said that by continuously monitoring the hull and propeller any regression could quickly be seen.
For full block vessels, such as bulkers and tankers, less data would be needed due to their lower power, thrust and speed, he said.
