Biofouling increases surface roughness and effective diameter of offshore structures, leading to higher drag forces.
This study investigates mussel biofouling effects on mooring-line cylinder. 3D-printed mussel sleeves developed at Nantes Université represent smooth and rough fouled conditions. Mussel growth increased drag by ~36% compared with smooth cylinders.
