Abstract
Measured jacket brace member axial loads are compared with predictions based on conventional static structural analyses. The measured to predicted member load ratios are shown to be lognormally distributed. Slightly conservative predictions are obtained, on the average, using drag and inertia coefficients of 0.7 and 1.7, respectively, and with no consideration of current or marine growth. A study of member loads vs. total wave load (shear) demonstrated that the wave shear distributions can be directly inferred from the member load distributions. For the larger waves, a median or bias of approximately 0.93 was estimated for the wave load with a coefficient of variation of approximately 0.18. A parameter study indicates that the addition of large currents and levels of marine growth, especially if the drag coefficient is increased because of roughness, results in extremely conservative wave load estimates.
