PPG has completed its 200th vessel dry docking using electrostatic application of marine fouling control coatings, nearly three years after introducing the technique to the global shipping market.
The project was completed on the Stena Britannica, a ro-pax vessel operated by Stena Line, at the EDR Antwerp shipyard in Belgium. The team applied PPG Sigmaglide 2390 fouling release coating, a silicone-based, biocide-free solution, using the electrostatic application method.
The application technique uses an electrostatic spray gun to guide coating particles onto a grounded metal surface, delivering even coverage and uniform film layers that help enhance smoothness and fouling control performance. Compared to traditional airless spray methods, electrostatic application is intended to improve paint transfer efficiency and significantly reduce overspray, material waste and carbon emissions.
Dennis Tetzlaff, COO Fleet, Stena Line, said: “In an industry that makes up 3% of global greenhouse gas emissions, we take responsibility for our impact on the environment. Our target is to reduce CO2 emissions from our vessels by 30% by 2030, based on a 2019 baseline. We are taking substantial steps to drive down our carbon footprint and decrease any negative impact on biodiversity. Collaborating with partners like PPG allows us to adopt solutions that help address global challenges.”
Electrostatic application offers Scope 3 carbon life cycle savings compared to traditional application methods, since fewer raw materials need to be extracted, manufactured or transported. These reductions are in addition to the operational carbon savings achieved by vessels coated with high-performance, low-friction solutions such as PPG Sigmaglide 2390, which help ship owners reduce fuel consumption and Scope 1 emissions.
Jan Willem Tegelaar, PPG global marine platform director, Protective and Marine Coatings, added: “This 200th electrostatic application milestone demonstrates how industry collaboration can drive real sustainability progress in marine coatings. Working with Stena Line from the start of this journey, we have delivered solutions that help shipyards and operators reduce both operational and embodied carbon footprints. With our premium hull-coating technologies, such as the PPG Sigmaglide 2390 coating designed for electrostatic application, PPG is the only marine coatings provider offering both types of carbon-reduction benefits in one integrated solution.”
