Marine riser and underwater wellhead system design analysis method, system and device

The invention relates to a marine riser and underwater wellhead system design analysis method, system and device. The marine riser and underwater wellhead system design analysis device comprises a database module, a system design and optimization module, a top tension design and optimization module, a strength evaluation module, an operation window analysis module, a one-key design and analysis module and a report generation module. Basic data in the database module is utilized to complete configuration design and top tension design of the marine riser and the underwater wellhead system; based on the design result, strength evaluation and operation window analysis of the marine riser and the underwater wellhead system in the installation and recovery mode, the connection mode and the suspension mode are carried out, and the structural strength of the marine riser, the stability of the underwater wellhead and the operation early warning limit are obtained; and synthesizing the design analysis result to generat
