PPG Completes 200th Drydocking Using Electrostatic Coating Application

Why It Matters

The achievement proves electrostatic marine coatings can be scaled commercially, delivering measurable emissions cuts and cost efficiencies that meet tightening regulatory and ESG expectations.

Key Takeaways

• 200th electrostatic drydock completed on Stena Britannica.
• Electrostatic spray cuts overspray, waste, and carbon emissions.
• Sigmaglide 2390 provides biocide‑free fouling release.
• Technique offers Scope 3 lifecycle carbon savings.
• Supports Stena Line’s 30% CO2 reduction target by 2030.

Pulse Analysis

Electrostatic application is reshaping marine coating practices by marrying precision engineering with environmental stewardship. Unlike traditional airless spray, the charged‑particle approach adheres paint directly to the hull, eliminating excess mist and ensuring a consistent film thickness. This technical advantage translates into lower material consumption and reduced volatile organic compound emissions, positioning electrostatic coating as a compelling alternative for shipyards seeking to improve operational efficiency while meeting stricter environmental standards.

The sustainability implications extend beyond the shipyard floor. By delivering a smoother, low‑friction surface, Sigmaglide 2390 reduces hull resistance, which directly cuts fuel burn and Scope 1 emissions for operators. Simultaneously, the reduced need for raw material extraction and transport delivers Scope 3 lifecycle carbon savings, a critical metric for companies reporting under the GHG Protocol. For carriers like Stena Line, these dual benefits support ambitious decarbonisation targets—30% CO₂ reduction by 2030—and help mitigate the maritime sector’s 3% share of global greenhouse‑gas output.

From a market perspective, PPG’s milestone signals that high‑performance, environmentally friendly coatings are moving from niche trials to mainstream adoption. The company’s integrated solution, combining a biocide‑free formulation with an efficient application method, offers a differentiated value proposition that can attract ship owners facing rising regulatory pressure and investor scrutiny. As more fleets prioritize ESG performance, the demand for such carbon‑reduction technologies is likely to accelerate, cementing electrostatic marine coatings as a growth engine for the protective‑coatings industry.
