This spatial and temporal density data was used to compute gravity loads due to slug flow (centrifugal and Coriolis forces were found to be negligible), which were fed into the OrcaFlex software...

.... The measured time series at the strain gauges are then used to reconstruct the linear combination of modal responses which gives at those locations the same values on the 3D FE model as measured. The modes are defined as the response of the structure on selected load cases and a specific methodology...

...-bubble passes a riser node. The other is at much longer period (~10-30 minutes) due to global weight variations, which are due to spatial integration of density time series from sag bend to TDP. These long period fluctuations drive the TDP fatigue. Finally, results from a preliminary field...

... presented as three-hour time series at 0.15 second increments. The general approach for prediction of extreme responses was to take the peak values (maxima or minima) during the three-hour simulation, and then use a Weibull III statistical analysis to determine the most-probable-extreme value. Operating...
