AkzoNobel’s Marine Coatings Business Leads the Way in Supporting the Decarbonization of the Marine Industry


Global shipping currently equates to 2.5% of all CO2 emissions and, under IMO carbon intensity rules, the industry must reduce its total emissions by 50% by the end of 2050.

A buzzword in the industry for decades has been efficiency, and many ship operators and ship owners are now placing more emphasis on it for the benefit of the maritime industry as a whole.

Coatings have an important role to play in helping fleets become more efficient. The increase in drag due to biofouling on a ship’s underwater hull has one of the largest impacts on fuel consumption and CO2 emissions.

AkzoNobel’s marine coatings business has been at the forefront of innovation to support industry decarbonization goals and has more recently developed a number of solutions that help improve performance and sustainability and are aimed at to lead the industry towards a more sustainable future.

One such solution is its new service – the Carbon Intensity Indicator (CII) Calculator. This is AkzoNobel’s unique tool that determines a ship’s overall efficiency and predicts its carbon output, how it will be rated under new IMO regulations and, most importantly, what shipowners ships can do to improve their rating.

The tool is independently verified and has already received positive feedback from customers to predict the impact of coating choice on the CII rating during the mooring cycle and ensure it will comply with legislation which will come into force in January 2023.

It works using AkzoNobel’s Intertrac® Vision tool, which uses collective analysis of big data from multiple points regarding ship performance over multiple years and the results it displays are calculations of reductions needed for a ship’s carbon output to improve its rating. .

Selecting the right coating scheme will help a vessel’s efficiency, such as AkzoNobel’s proven industry solution – Intercept® 8500 LPP – a next generation self-polishing silyl methacrylate copolymer antifouling coating.

Its unique formulation includes an optimized biocide package that not only delivers a clean hull, but also a guaranteed 1.5% speed loss on the docking cycle.

The product can also be used in conjunction with AkzoNobel’s Intertrac HullCare package, which can further reduce CO2 emissions and fuel consumption when the vessel is in service. Over 560 vessels have been coated with the product since its launch, with a number of customers having coated their vessels with Intercept 8500 LPI after successful in-service performance for up to 60 months.

Another of the company’s innovations is Intertrac HullCare which combines high-performance hull coating technology from AkzoNobel Marine Coatings’ International® range, state-of-the-art ROV (Remote Operated Vehicle) inspection and performance monitoring of the Big Data with proven hull cleaning techniques aligned with BIMCO. industry standard – resulting in the most environmentally sustainable hull management package in the industry to date.

Customers have the option of choosing between a five-year or 10-year program to help operators optimize fleet efficiency. Over a 10-year period, Intertrac HullCare can help operators significantly reduce CO2 emissions by up to 34,000 tonnes and save €4.6 million in fuel compared to a typical fouling control system five years, ensuring smooth and clean operation. the hulls are maintained.

This has been developed in collaboration with customers to provide solutions that improve their financial and sustainability performance as well as that of the maritime industry as a whole. The advanced remote inspection and cleaning technologies used have been created and tested in close collaboration with the world’s leading equipment suppliers over the past five years.

Intertrac HullCare uses cleaning technology, with recovery as standard. Some ports do not allow scavenging without recovery, which means that any problems caused by expensive on-board cleaning systems, which do not have scavenging as standard, are avoided.

AkzoNobel’s marine solutions innovators and scientists are committed to driving the industry’s evolution towards a more sustainable future, ensuring shipowners meet and exceed emissions reduction targets of carbon.

Fleet and vessel owners looking to track and improve their carbon output can schedule an appointment with AkzoNobel’s team of experts to discuss CII and HullCare in more detail.
