RR19 - Sensitivity of jack-up reliability to wave-in-deck calculation
Represents a study undertaken to determine the effects of air gap erosion and subsequent hull inundation on a typical jack-up structure. A wave-in-deck loading model was developed ("The MSL model") and a sensitivity study was performed to assess the important factors affecting the loads generated during inundation. Additionally, a typical jack-up structure was modelled using the USFOS structural analysis package in order to determine the dynamic response of a jack-up to storm loading where inundation occurs. The effects of response to previous waves, foundation modelling complexity and hull inundation levels were assessed by performing a number of short duration time-domain analyses. It has been found that wave-in-deck loads cause a significant increase in environmental loading once inundation occurs.
