Barry Kidd, sector manager at AkzoNobel’s Marine Coatings Business, supplier of International’s range of coatings, explains the key role of the upcoming ISO 19030 standard in delivering greater transparency in hull coating performance monitoring. ISO 19030 – Ships and marine technology – Measurement of changes in hull and propeller performance represents an important milestone in the shipping industry’s continued journey towards enhanced monitoring of hull and propeller performance. The standard, which will be finalised shortly, consolidates the latest academic and industry knowledge and understanding into an agreed and standardised method to measure the performance of a vessel through the water. A key objective of the standard is to provide all ship owners and operators with a clear and transparent framework with which to gauge the relative merits of hull and propeller efficiency improvements, which can be implemented for vessels with a range of performance measuring capabilities. The new standard will also enable the transparent comparison of datasets, providing a sound basis for more effective settlement of charter party disputes and the sharing of benefits that may result from the adoption of the latest hull coatings or the replacement of a propeller, for example.
A breakdown of ISO 19030In conjunction with other industry stakeholders spanning the shipping supply chain, AkzoNobel’s Marine Coatings Business, International, has played an influential role in the development of all parts of the new ISO 19030 standard. ISO 19030 focuses on four key performance indicators (KPIs) that are based on power and speed. The first is the measurement of ship performance before and after a drydocking. The second KPI tracks the performance of the hull and propeller while a vessel is in operation. A third triggers the point at which maintenance may be required, including cleaning the hull or polishing the propeller, for example, and a fourth KPI monitors the impact of such maintenance.
ISO 19030 is broken down into three parts:
- Part 1 sets out the objectives and purpose of the standard, which is to provide an agreed and standardised method to measure the performance of hull coatings and propellers.
- Part 2 provides a method by which automated data collected from sophisticated on-board sensors can be used to measure efficiency gains with an estimated accuracy of plus-or-minus 1-2%. These measurements take in a number of variables such as the delivered shaft power, speed through water etc. It is estimated that Part 2 is currently applicable to around 10% of the commercial fleet (less than 3,000 vessels) that are equipped with the necessary performance measuring sensors and continuous monitoring systems.
- Part 3 is founded on a tiered system of potential methods for monitoring, including noon report data collection. This will enable the vast majority of the industry to ensure, and demonstrate compliance with, the new standard. AkzoNobel in particular championed this part of the standard, as part of its belief that the widest possible number of ship owners and operators in the industry should be able to demonstrate compliance, and in consideration of the tough economic climate.
