Understanding
Biofouling
impacts More Than You Think
Reduced Efficiency
​
Biofouling increases drag, leading to higher fuel consumption and operating cost.
Asset Protection
​
Long-term fouling can cause corrosion, coating damage and costly maintenance.
Environmental Responsibility
A fouled hull can transfer invasive species, disrupting sensitive marine ecosystems.
Early Intervention
​
Regular inspections and cleaning prevent build-up and reduce downtime.
WHAT IS BIOFOULING
​
Understanding the Challenge Beneath the Surface
​
Biofouling is the underwater accumulation of microorganisms, plants, algae and animals on the submerged surfaces.
It occurs naturally in all marine environments and can build up quickly on hulls, increasing drag, fuel consumption and the risk of invasive species transfer.
Effective biofouling management is essential for vessel performance, asset protection and environmental stewardship.
THE BIOFOULING PROCESS
How Biofouling Develops
Biofouling begins as a microscopic layer and develops into a complex and resilient mass. Without timely intervention, it drives costs, increases fuel consumption and accelerates corrosion. Proactive inspection and appropriately timed hull maintenance can help interrupt this cycle before heavier fouling becomes established.
1. Condition Film
​
Microscopic organisms form a thin layer on the hull.
​​
​
Time: Hours to Days
2. Organism Growth
​
Algae and soft fouling species start to settle.
​
​
​
Time: Days to Weeks
3. Hard Fouling Establishment
Barnacles, mussels and other hard organisms attach and grow.
​
Time: Weeks to Months
4. Mature Fouling
​
A thick, complex fouling mass impacts performance.
​
​
Time: Months to Years
