Jotun has released a new report, Biofouling in Shipping, detailing the consequences of inadequate biofouling management. Based on a survey of 1,000 ship owners and operators across 11 countries, the report reveals growing awareness of hull performance's role in emissions reduction and regulatory compliance—but also persistent knowledge gaps.

According to the report, 41% of respondents said they have faced regulatory penalties tied to biofouling issues, and 38% have been denied port access due to non-compliance. Nearly half (49%) reported avoiding ports with strict regulations—a trend that could prove unsustainable as global frameworks evolve.

“Although 79% of respondents consider hull performance a top priority, only 31% believe their company has adequate knowledge of available solutions,” said Morten Sten Johansen, global category director for hull performance at Jotun. “This highlights the need for greater understanding and strategic planning.”

Operational impacts were also significant. More than half of those surveyed reported experiencing fuel inefficiencies due to biofouling, while 1 in 5 acknowledged not using the most effective antifouling coatings for their fleets.

“With tighter margins and global regulations on the rise, minimizing hidden costs is more important than ever,” said Johansen. “Ship owners that proactively embrace tailored biofouling management strategies stand to gain a clear competitive advantage.”

The report was presented during Nor-Shipping as part of Jotun’s Clean Shipping commitment and calls for shipowners to rethink biofouling as a strategic priority in light of regulatory, environmental, and economic pressures.
