Finite element analysis of local strength of deepwater jacket platform skirt sleeve
The skirt pile of the deepwater jacket platform makes the platform have good overall carrying capacity,and plays an important role in offshore oil and gas development and offshore wind power development.An analysis software specifically used in jacket,SACS,cannot conduct local detailed mechanical analysis on the complex structure of the skirt pile sleeve.However,the skirt pile sleeve is the key component connecting the pile group and the jacket body and is crucial to the stability and safety of jacket structure.SACS special engineering software combined with ABAQUS generic finite element software is utilized to carry out the strength analysis of the skirt pile sleeve.Firstly,the static calculation of the overall structure of the deepwater jacket is carried out by SACS software to ensure that the overall performance of the jacket meets the requirements.Then,the pile head force,bending moment,shear force,and the boundary conditions of each cutoff position of the pile group sleeve under the maximum UC condition in the static analysis results of the overall model are extracted respectively,and the detailed structural finite element model of pile group sleeve established by ABAQUS is input for more accurate local check,thus ensuring the safety and stability of the deepwater jacket platform and skirt sleeve.
