8. Antifouling – Friction drag reduction
 Raft exposure studies (benchmarking, registration)
 Erosion/ self-polishing behaviour of antifouling coatings
 Friction drag tests of coatings with and without fouling
 Foul release tests on rotor test equipment
 Efficacy testing of new antifouling techniques (e.g. ultrasound, UV) or
coating products
 Consultancy on regulatory aspects
 Inspections on hull and coating condition
 Experience in European projects
Measured in FDM:
23 % friction drag increase
