Published in late 2016, the voluntary ISO 19030 standard defines a set of performance indicators that enable quantification of changes in the performance of hulls and propellers, including before and after the application of a new coating.
A boon to shipowners and operators, the standard has paved the way for generating a qualitative assessment of return on investment (RoI).
In a newly published whitepaper, Jotun describes how they worked together with over 50 industry stakeholders to develop the standard and provides an overview of developments, challenges and advances to vessel performance improvement.
Environmental performance regulations are on the rise, leading to increased interest in performance monitoring systems as operators work to achieve greater efficiencies. Jotun points out that “Poor hull and propeller performance alone is currently estimated to account for around 10% of the world’s fleet energy cost and corresponding greenhouse gas emissions.”
And the industry agrees:
“The use of proven quality hull coatings is another area where the operators – and the industry – can achieve significant impact, with both environmentally and financially sustainable solutions. Indeed, the choice of a high performance antifouling system is important since fouling significantly reduces a ship’s speed whilst increasing fuel consumption and hence operating costs and exhaust emissions. Reductions in efficiency due to fouling could typically vary from around 5% – 20% so coatings are mentioned frequently in rules and guidelines as a major contributor to improved performance.”
The introduction of ISO 19030 moved performance monitoring beyond the more easily quantified factors – such as fuel consumption and engine performance that contribute to greater efficiencies – to set forth measurement methodology and defining performance indicators for hull and performance maintenance, repair and retrofit activities.
The standard in practice
The whitepaper demonstrates ISO 19030 in practice with a case study in which Jotun applied the ISO 19030 framework to an LNG carrier over an 8-year period. Measuring a number of parameters revealed that maintenance triggers and maintenance effects lead to significant overall efficiency improvements.
While the case study demonstrates the value of collecting massive amounts of data, operators can opt for more traditional methods to implement the standard:
“The cost of outfitting ships with performance measurement systems can be done in an inexpensive way. The basic approach in ISO 19030-3 is to use noon reports. This way, operators will at least have indications on overall performance. By investing in some additional equipment, the accuracy can be significantly improved. In order to comply with ISO 19030-2, which is based on high frequency data, a datalogger, torque meter and some cabling is required. Alternatively, flowmeters can be used. Both torque meters and dataloggers are becoming very affordable these days, allowing for a quick return on investment.”
The opportunity for operators to reap the benefits of ISO 19030 is clear, yet Jotun’s market research has revealed that, “…only 15% of the world’s fleet is equipped with high frequency performance monitoring equipment and only around 8% are using the data efficiently.”
As Jotun sees it, ISO 19030 is, “…a good starting point to offering a level playing field and the adoption of industry-wide best practices and transparency.” Moreover, this standardised approach with data-driven solutions – including the use of proven coatings – can significantly contribute to lower fuel costs and reduced emissions.
Jotun offers Hull Performance Solutions (HPS) – aligned with ISO 19030 and covering SeaQuantum antifouling coating systems – which combines the comprehensive ship data from several performance monitoring companies with the expertise of Jotun analysts who identify short-term patterns as well as long-term trends. This service – already in operation on board approximately 900 vessels across the globe – enables Jotun to suggest maintenance strategies based on budget and a ship’s operating profile.
