Added Hydrodynamic Loading due to Sacrificial Anodes

Downie, M. J. / Murray, B. A. / Bettess, P. / Haswell, J. V.

Abstract There is a scarcity of data relating to the hydrodynamic loading due to sacrificial anodes. A method of calculating factors to apply to circular cylinder force coefficients, using the discrete vortex method is described. The results are presented for uni-directional and oscillatory flows. Equivalent force coefficients are calculated and used in a Morison type analysis of a simple jacket structure in a current and in waves. The overall in-line loading was found to be increased by as much as 9% in modest environmental conditions.
