The effect of marine growth on the performance of fixed offshore  platforms in the North Sea

Abstract

No details regarding species composition. From the Abstract: “Marine fouling is found to influence the loading of an offshore structure in at least five ways: 1) Increased tube diameters, leading to increased projected area and displaced volume and hence to increased hydrodynamic loading. 2) Increased drag coefficient, leading to increased hydrodynamic loading. 3) Increased mass and hydrodynamic added mass, leading to a reduced natural frequency and hence to an increased dynamic amplification factor. 4) Increased structural weight, both in the water and above the water level in air. 4) Effect upon hydrodynamic instabilities, such as vortex shedding.”
