K-Type, Inverse K-Type and X-Type Legs Stability Analysis of Jack-Up Offshore Platform

Abstract:

The force situation of truss legs has an important impact on the jack-up offshore platform. The finite element analysis on three types truss leg was made, and the stability of the three types truss leg under preload, operating and storm survival condition was discussed. The result showed that the maximum stress was in the chord; they met the design requirements; K type, inverse K type can save material, and they both met resonance requirements. The former had a better stability under preload condition, and the later had the best stability under operating, storm survival condition.
