Eco-Friendly Hull Coating Claims to Reduce Ship Emissions and Fuel Consumption

PPG offers a solution to the issue of underwater fouling control hull coatings impacting fuel consumption and emissions intensity for ship owners and operators. Their PPG SIGMAGLIDE® 2390 fouling release hull coating, made with a 100% pure silicone binder system, can reduce emissions by up to 35% compared to traditional antifoulings. This product supports compliance with short-term and upcoming IMO greenhouse gas (GHG) measures, contributing significantly to industry net zero targets. The coating delivers GHG savings through reduced power consumption (up to 20%) and minimal speed loss of less than one percent.

In addition to reducing emissions, PPG’s electrostatic coating application technique offers further sustainability benefits. This method, which has higher transfer efficiency compared to airless spraying, guides electrically charged paint particles toward the vessel’s surface for even distribution and a uniform, long-lasting film layer. The reduction of overspray and waste in the operation leads to a cleaner process. PPG’s formulation of the fouling release coating makes it suitable for electrostatic application, a technology recognized by cruise owners as highly effective for demanding operations.

The International Maritime Organization (IMO) is implementing measures to reduce GHG emissions, with targets of a 20% reduction by 2030, 70% by 2040, and net zero emissions by 2050 compared to 2008 levels. PPG’s silicone-based coatings, particularly when applied electrostatically, offer a solution for the cruise industry by minimizing overspray and contamination in accommodation areas during spraying. With the industry’s focus on meeting global emissions reduction goals, products like PPG’s fouling release hull coating play a crucial role in helping ship owners and operators achieve compliance and contribute to a more sustainable maritime sector.
