Selektope® keeps the ship hull free from barnacles

By providing ingredient technology to power up the antifouling system

Fouling is a pressing environmental and financial problem.

Prevention rather than cure is I-Tech’s approach to tackling the global issue.

Only with a barnacle free hull can global emission targets be met.

The Selektope® biotechnology is a vital ingredient in the antifouling mix to eradicate hard fouling, ensuring continually clean hulls, optimal business and environmental performance.

Selektope has provided power to antifouling coatings used on over 500 vessels.


Did you know that, when a hull is covered by 10% barnacle fouling, 36% extra power from the engine is required to maintain the same speed through water.

The power of Selektope® keeps tanker barnacle free during 60 months of trading on global routes.

Available antifouling coatings containing Selektope® has been used on more than 500 vessels.
