THE EFFECTS OF MARINE GROWTH ON OFFSHORE STRUCTURES

 

1)    The increasing thickness of the marine growth increases the member’s effective diameters, leading to increased projected area and displaced volume, and hence increased dynamic loading;

2)    With the attachment of marine growth, a member’s surface is roughened. The increase in surface roughness gives rise to changes in both the drag and inertia coefficients, which strongly affects the hydrodynamic response of the structure. Large differences were found in the maximum hydrodynamic loads for different marine growth thicknesses values because not only the jacket mass was affected but also the added mass was increased.
