After three years it is now time for the ISO Committee to decide how to proceed with it. By Richard Marioth Without data you’re just another person with an opinion« (W. Edwards Deming) ... In an era, where the industry talks about topics that include the term »4.0«, data is a must have. By agreeing on definitions and methodologies to process data, more harmony in the analyses and interpretation can be achieved. This leads to more trust and acceptance. ISO 19030 describes a standard methodology of hull and propeller performance assessments to analyse retrofit, maintenance and dry-docking effects. The document is divided into three parts. Part 1 outlines general principles, part 2 the default method and part 3 alternatives to the default. During the development process, the working group found out quickly that analysing hull and propeller performance is complex as one has to deal with many uncertainties. Hence, a significant part of the first part deals with descriptions of how the uncertainties where assessed and what the achievable accuracies are. As the requirements regarding the measurement accuracy and frequency of the default procedure, described in the 2nd part, reduce the application field of the standard to only a minor part of the world’s fleet, the 3rd part of the document outlines alternative methods, which vary in accuracy and ease of use. Most of these alternatives, however, have a significant lower accuracy than the default method. Impact on industry The standard has put the limelight on measuring hull and propeller performance, along with regulations such as MRV. The industry realizes increasingly the importance of data, not just for More transparency, objectivity and trust willingness Geir Axel Oftedahl, heading Jotun’s strategical business development Marine, was the project manager of the ISO 19030 working group. Why has ISO 19030 been developed? Geir Axel Oftedahl: We were discussing, with different stakeholders, the importance and potential of improving the hull performance of the world fleet. We agreed with IMO that ISO would be a good place to create such a standard. I was appointed as the project manager and we had a big working group with 53 members. It was one of the biggest working groups for such standard developments. What were the intentions of the standardisation? Oftedahl: They were to create transparency, objectivity and trust, one could say, meaning that it is clear how certain conclusions were made. How do you see the effects of the ISO standard on the industry now, three years after the release? Oftedahl: I think the ISO 19030 has three major effects. First: Awareness: The most important fact to me is that it has created an awareness of the importance of hull and propeller performance in the industry. There is a huge improvement potential. Second: Reference. The standard is a common reference that everyone can refer to. One can calculate according to the ISO, calculate according to an own method and explain why certain deviations occur. Third: No personal judgement. The ISO 19030 standard has its limitations, but what it is doing better than any other methodology is that it lifts judgement from the person who does the analysis. Would you say that ISO 19030 helped companies like yours to promote premium paints? Oftedahl: I would not take the starting point there. The ISO standard puts the fingers on ourselves. Now we are confident that when we have a high-quality product, then we have the data and methodology to verify that it works. This, of course, helps us to demonstrate the differences of a bad and a good solution. Furthermore, the ISO 19030 standard created more awareness of the importance of the choice of paint. It is a strategically important decision for a shipping company and should be treated like that. Geir Axel Oftedahl © Jotun Do you personally think that it is time to review the ISO 19030? Oftedahl: I personally think that it is a good time to review the ISO standard, as the analysis technologies in this area have moved forward. A lot of good ideas and approaches have been presented for example at the HullPIC events. So, I definitely see a substantive point for reviewing the ISO standard. Would your company take a leading role in the update process again? Oftedahl: I am not sure whether we should. There was quite a big group of people who have worked with it, so I see several people or organisations that could lead the review process, but it is not my task to decide this. n 40 HANSA International Maritime Journal 01 | 2020

Major ship operators have used performance monitoring for a long time, but for small and medium ship operators the average awareness for performance monitoring has grown massively since the release of ISO 19030. On the commercial side, ISO 19030 is currently used by some paint suppliers for paint performance guarantees. This might be one of the reasons, why premium paints are increasingly sold. »ISO 19030 is a transparent way to track the value generated by high-end hull coatings; when combined with paint supplier guarantees this is a good recipe for moving hull coating business cases across the line into performance improvement investments,« says Jonathan Dowsett (Eagle Bulk Shipping). Due for a review? Although ISO 19030 has moved the knowledge in the field much forward, most people regard it as far from being perfect. Actually, it is suggested within the document itself to cover certain aspects such as wave and swell correction during future reviews. Also, progress in information technology suggests an update. »There is much more data used from the public domain nowadays. AIS data is used more frequently and there is also much better data available on currents and on waves. These are good public sources, which were not considered during the standard development,« says Johnny Eliasson (Chevron), who sees the standard due for a review. In a survey conducted during Hull- PIC 2019, the answer to the question of where exactly the standard needs improvements was answered differently by the participants. However, 62 of 63 responders saw the need for a review of ISO 19030 and more than half of the participants believed that significant improvements were required. So, when hull and propeller performance experts think about ISO 19030 these days, an old U2 song might go through their minds: »I can’t live – with or without you«. n Spende und werde ein Teil von uns. seenotretter.de Einsatzberichte, Fotos, Videos und Geschichten von der rauen See erleben: #teamseenotretter Spendenfinanziert Anzeige 180 x 75.indd 1 17.05.18 14:53 HANSA International Maritime Journal 01 | 2020 41
