摘要：In order to evaluate the safety after pile penetration related to the soil around the jack-up rig locally scoured by wave flow, a three-dimensional finite element model for local scour was developed utilizing numerical simulations based on the computational fluid dynamics. The flow field variations around the spudcans were accurately simulated by solving the Navier-Stokes equations. Based on actual geological site parameters and sea conditions, an engineering analysis method applicable to the local scour problem of the soil around the spudcans was developed. The numerical results were compared with the experimental results. The local scouring effects on soil around the spudcans of the jack-up rig were discussed at different penetration depths and operational cycles. The results show that the penetration depth of the jack-up rig spudcans under the joint action of wave current and sea current has a significant effect on the local scour depth of the soil around the spudcans. Shallower penetration depth makes the spudcans more susceptible to local scour. Targeted scour protection measures were developed to reduce the local scour depth around the spudcans according to varying penetration conditions, which can effectively reduce the operational risks. 漏 2024 University of Petroleum, China.
