摘要
A generally cylindrical element 10 adapted to be submerged is described. The generally cylindrical element 10 has an outer surface 11 in contact with water in use. The outer surface 11 has repeating shapes 20 of at least two columns provided on the surface 11, for example hexagons 20, where each of the repeating shapes 20 is Columns are separated from other or adjacent column(s) by groove arrangement 30. Each shape 20 in the column is separated from or adjacent to each other by at least one groove 30. This configuration of the surface 11 reduces the vortex induced vibration (VIV) and/or drag that can act on the generally cylindrical element 10 when the generally cylindrical element is submerged in the water body. Order.
