| Abstract: | The theory of leg structure analysis for selbelevating drilling units under tran- sit condition is illustrated and as an example, a jack-up with truss legs is analyzed by FEA method, which can explain the process and method for leg strength analysis of jack-up units. This paper may be helpful to the rig owners, operators and designers. |
