Fatigue of jacket platforms: effect of marine growth loading

24th International Conference on Offshore Mechanics and Arctic Engineering: Volume 2International audienceAfter decades of developments of methods and software, reassessment of jacket structures is still a challenge. This paper focus on marine growth effects in case of fatigue behavior for Jacket offshore structures. Two main items are pointed out: selection of marine growth profile and modeling of hydrodynamic coefficients in presence of marine growth. A complete approach is provided and completed with both sensitivity and uncertainty studies
