When the owner of an offshore platform wants to extend the production time beyond the designed life of the platform, he has to convince himself and a third-party certification body of the platform’s structural integrity. As part of this re-certification, engineers perform a structural analysis.
For this particular task, SACS software is used. All the major events, like collisions or modifications, are taken into account. In this manner, the in-place situation is analyzed together with the fatigue analysis. Also, Metocean data are integrated into the analysis to get a good picture of the integrity status during the certified period. The investigation is complete after preparing a basis for structural inspection and inspection plan, which were also carried out in the Conbit office.
