Leading marine coatings supplier Jotun was involved in the working group that developed the new ISO 19030 standard. Class society DNV GL also participated.
Speaking in London in March Stein Kjølberg, Jotun’s global sales director for hull performance solutions (HPS), said that there was a need for a global standard to measure the effectiveness of hull coatings with regard to their impact on the fuel efficiency of ships. “Overall hull performance is still poor. Today the average speed loss between drydocks is 12 per cent, which equates to a significantly increased fuel cost,” he said.
The ISO 19030 standard originated from Jotun’s measurement method developed as part of its HPS. Mr Kjolberg said that development work for the new standard started in 2013 so it has taken about three years to result in a new standard. It is based on the change in onboard power required to achieve a given speed. The standard comprises four performance indicators: In service performance, drydocking performance, maintenance trigger for hull and propellers, and the impact on hull and propeller performance
Mr Kjølberg commented: “ISO 19030 will assist owners’ decision making, increase transparency and produce closer alignment between stakeholder interests including vendors, buyers, builders and charterers. It should lead to reductions in energy costs and greenhouse gas emissions.”
Jotun highlighted results from an earlier application of HPS to support its claims. In 2012 container ship Cosco Europe was coated using the HPS system with Jotun’s SeaQuantum X200 antifouling. According to its analysis, the vessel saved US$4.5 million in fuel costs.
Alfie Ong, Jotun Marine Coatings vice president, said: “HPS has now been applied to over 400 vessels worldwide since its launch in 2011. As we get more long-term data from the system, which is the first solution of its kind to measure performance in line with ISO 19030, we get the hard evidence to prove that HPS delivers the cleanest hulls, the highest efficiency and the best environmental performance on the market.”
Mr Ong said that the ship, which received the HPS treatment in October 2012, recorded a speed loss of just 0.76 per cent, measured to ISO 19030, compared with a market average of 5.9 per cent for vessels treated with standard antifouling solutions.
