AkzoNobel Releases Ship Coatings Data
Global paints and coatings manufacturer AkzoNobel recently released new performance data on its Intersleek1100SR coating, a biocide-free fouling control coating with slime release technology that has been applied to over 3,000 vessels.
According to a release from the company, Intersleek1100SR was released in 2013 and works by removing slime built up during docking, then releasing it when the vessel travels through the water to help reduce drag, improve fuel efficiency and reduce carbon dioxide emissions.
AkzoNobel states that performance data for the coating was gathered from ships coated with Intersleek over the past 10 years. The data reportedly shows that the coating has helped to reduce ship fueling costs by $8 billion and cut down 41 million tons of CO2 emissions.
Chris Birkert, AkzoNobel’s Marine Coatings Segment Manager, stated that the numbers are "promising" when looking at the overall performance data that has been compiled over the last two decades.
“Together with our customers, Intersleek has the largest foul release track record, gathered from 20 years of vessel performance data that proves our coatings have helped save ship owners $19.6 billion dollars in fuel costs and 103 million tons of CO2 to help them hit carbon targets.”
The company states that it hopes for Intersleek to contribute to the company’s goal of reducing carbon emissions across its full value chain by 50% by 2030. This goal is reportedly part of an effort to become a carbon neutral company by 2050.
The International Marine Organization (IMO) reportedly has similar goals. In 2023, it announced new carbon targets for the fleet, expecting a 20% reduction in emissions by 2030, a 70% reduction by 2040 (compared with 2008 levels) and net-zero emissions by 2050.
Demand for biocide-free technology has reportedly risen in the past 18 months as ship owners work to cut CO2 emissions to align with new carbon regulations and look for proven solutions.
Earlier this month, AkzoNobel announced that the first large cruise ship built in China had begun its voyage, coated with paint from the company’s Marine, Protective and Yacht Coatings business.
According to an emailed release, the 5,246-passenger Adora Magic City was coated with the AkzoNobel’s Intersmooth fouling control technology.
The brand was reportedly specified on the hull of the milestone vessel because of its high durability, low VOC content and strong application properties.
The release stated that the ship is 323.6 meters (about 1,062 feet) long and has a 1,292-person crew capacity. The ship was reportedly built by Shanghai Waigaoqiao Shipbuilding Co., Ltd., and the launch was meant to mark a new beginning for the Chinese cruise ship new-build sector.
The newly launched ship weighed 135,500 tons, reportedly had over 25 million different parts and was produced with the cooperation of over 30 countries and over 8,000 specialized suppliers.
AkzoNobel stated that it can offer a strong portfolio of coatings to protect and enhance vessel performance when facing different challenges, like impact and abrasion, chemical resistance and biofouling accumulation.

In October 2021, the company announced the launch of its new environmentally sustainable hull management package.
According to AkzoNobel, the Intertrac HullCare would be able to provide ship owners and operators with fuel and emission savings through its ability to combine remote inspection, advanced cleaning technologies and data monitoring that already sets new standards for operational efficiencies.
The company further noted that customers who chose the option of a ten-year scheme could achieve step-change reductions in CO2 emissions of up to 34,000 tons and fuel savings of €4.6million (about $5.3 million).
Also, in July 2022, AkzoNobel unveiled its service to help support the decarbonization of the marine industry. The Carbon Intensity Indicator (CII) calculator would determine the overall efficiency of a vessel and predicts its carbon output, how it would be classified under the new IMO regulations and what shipowners can do to improve their rating.
According to the emailed release, global shipping equated to 2.5% of all CO2 emissions at the time. Per the IMO's carbon intensity rules, the industry needed to reduce its total emissions by 50% by the end of 2050. AkzoNobel reported that coatings had an important role to play in helping fleets become more efficient, as increased drag from biofouling on the underwater hull of a vessel was one of the biggest impacts on fuel consumption and CO2 emissions.
The CII calculator works by using AkzoNobel’s Intertrac Vision tool, which uses the collective big data analysis from multiple points regarding vessel performance over a number of years and the results it shows are calculations of what reductions are necessary for carbon output for a ship to improve its rating.
The company said that the tool had already gained positive feedback from customers for predicting the impact of coating choice on CII rating over the docking cycle and ensuring that it would be in compliance with the legislation that started in January 2023. It has also been independently verified.
