This paper presents the details of In-place analysis of fixed jacket Platform BD. The numerical model is prepared using ANSYS ASAS structural analysis computer system. Beam stick model has been used, with multi-level sub-structuring technique, to model the whole structure. Appropriate dead load, live loads and quasi-static action of 100 yr storm have been applied to the structure. The structure-pile interaction analysis has been performed using SPLINTER, a component of the ANSYS ASAS program suite. The platform is subjected to design action, i.e combination of permanent and variable actions, and the basic Integrity checks including member strength, stability and hydrostatic collapse have been performed.
