Abstract

There is disclosed a cladding section (8) for mounting upon an elongate underwater member and suppressing vortex induced vibration of it, the section comprising a unitary plastics moulding shaped to provide a tubular (10) portion for receiving the member, the tubular portion being split along its length at (14) and being deformable to permit the member to be introduced into the tubular portion, and the cladding section having at its exterior at least one feature (12) shaped to suppress vortex induced vibration. Rotational moulding of the cladding section is disclosed. The cladding section has an outer layer (24) incorporating anti-fouling material upon an inner structural layer (26).
