Challenges: Biofouling, Durability, and Sustainability

Acoustic oceanographic coatings are critical for ensuring the reliable operation of sonar systems, underwater sensors, and autonomous vehicles. As of 2025, engineers face a triad of persistent challenges: biofouling, durability under harsh marine conditions, and sustainability in both production and end-of-life management.

Biofouling remains a primary concern, as the accumulation of marine organisms on sensor surfaces can degrade acoustic performance and increase maintenance costs. Recent solutions include non-toxic, silicone-based fouling release coatings that minimize organism adhesion without relying on biocides. Companies such as AkzoNobel have advanced their silicone technologies, emphasizing reduced environmental impact while maintaining efficacy over multi-year service intervals. Nevertheless, even state-of-the-art coatings require periodic cleaning or reapplication, particularly in high-fouling regions.

Durability poses another significant challenge. Acoustic coatings must withstand intense hydrostatic pressures, temperature fluctuations, and mechanical abrasion while maintaining their acoustic impedance properties. Recent developments in polyurethane and epoxy-based coatings, exemplified by Henkel, aim to prolong service life and minimize signal attenuation. Ongoing research focuses on nanostructured and self-healing materials to enable longer deployment cycles and reduce maintenance requirements—though widespread commercial adoption is still in its early stages for these advanced materials.

Sustainability is becoming increasingly central to new product development and regulatory compliance. Traditional antifouling coatings often relied on copper or organotin compounds, which are now regulated or banned in many jurisdictions due to ecological concerns. Industry leaders such as Hempel and International (AkzoNobel) are investing in waterborne and solvent-free coating chemistries, alongside recyclable or biodegradable binders, to align with tightening global marine environmental standards. The shift towards sustainable coatings is expected to accelerate over the next few years, driven by both customer demand and international agreements like the IMO’s biofouling guidelines.

Looking ahead to the next several years, the sector is expected to focus on multi-functional coatings that combine fouling resistance, acoustic transparency, and environmental compatibility. Collaboration between coating formulators, sensor manufacturers, and marine operators will be critical in field-testing new technologies and bringing innovative solutions to commercial deployment. However, balancing functional performance with ecological safety remains a core technical and regulatory challenge for the industry.
