The increasing focus on reducing greenhouse gas (GHG) emissions in the shipping industry has brought attention to the vital role of antifouling biocides. These substances are integral to maintaining efficient vessel operations by protecting underwater surfaces from biofouling, a process where organisms like barnacles attach to a ship’s hull, increasing fuel consumption and emissions.
Despite concerns about their environmental impact, antifouling biocides remain indispensable due to their unique ability to provide active, continuous protection. Over 95% of the global shipping fleet relies on biocidal antifouling coatings, making them a cornerstone of maritime sustainability efforts.
Selektope: A Revolutionary Marine Biocide
Selektope, developed by I-Tech, represents a significant innovation in antifouling technologies:
- Low Concentration, High Effectiveness: Effective at just 0.1% of paint weight, it repels barnacles without fatal effects, ensuring long-term hull protection.
- Versatility: Used in a range of applications, from 60-month coatings for ocean-going vessels to leisure boat protection.
- Market Impact:
- Since its debut in 2015, 36 antifouling products incorporating Selektope have been commercialized.
- By 2024, sales of Selektope reached 20 tons, enough for 15 million liters of paint.
Emerging Trends in Antifouling Technology
The industry is witnessing the rise of low-biocide and biocide-free solutions, driven by stricter regulations and environmental awareness. Key developments include:
- Advanced Biocidal Coatings: Technologies that optimize biocide levels while maintaining efficacy.
- Hull Grooming and Surface Protection: Non-chemical alternatives to minimize biofouling.
Selektope is well-positioned in this evolving landscape, enabling paint manufacturers to create effective, low-biocide systems.
Regulation and Awareness
I-Tech emphasizes the need for better education about:
- Regulatory Frameworks: Extensive regulations ensure the safe use of biocides in marine environments.
- Sustainability Contribution: Biocides are essential for reducing shipping emissions and meeting decarbonization targets.
The recently published whitepaper, “Antifouling Biocides: A Key Contributor to Sustainable Shipping”, co-authored by I-Tech and global biocide suppliers, highlights these aspects and aims to foster a deeper understanding within the industry.
Antifouling biocides, particularly innovative solutions like Selektope, play a critical role in sustainable shipping by reducing biofouling, enhancing vessel efficiency, and minimizing environmental impact. As the maritime sector continues its transition to net-zero emissions, the responsible use and innovation of biocides will remain pivotal.
