How Marine Growth Impacts Fuel Efficiency and Performance

Fuel costs are one of the biggest expenses in commercial shipping. While many operators monitor engines and cargo loads, one hidden culprit often goes unchecked—biofouling.

This article explains how marine growth affects vessel performance and why proactive hull cleaning is crucial for keeping your fleet efficient and profitable.

What Is Biofouling?

Biofouling is the accumulation of marine organisms like algae, barnacles, and slime on submerged surfaces of a vessel. It begins as a microscopic film and evolves into thick layers of hard growth, especially in warm, nutrient-rich waters like those in Panama.

How It Affects Fuel Efficiency

Marine growth creates drag, forcing engines to work harder. According to industry studies:

• Light biofouling can increase fuel use by 10–15%
• Moderate biofouling: up to 30%
• Severe fouling: over 50% more fuel burned

Other Performance Impacts

• Reduced top speed and maneuverability
• Higher emissions (environmental compliance issues)
• Shorter lifespan of propulsion systems

Prevention = Profit

By implementing a hull cleaning and inspection schedule every 60–90 days, operators can:

• Maintain speed
• Save thousands in fuel annually
• Reduce environmental impact
• Prevent emergency dry docking
