In the framework of the studies on the DeepStar Theme Structures for deepwater in the Gulf of Mexico, contractors and research institutes have carried out series of pre-model test computations. The DeepStar Theme Structures are a turret moored FPSO, a classic SPAR and a standard TLP. The Theme Structures were exposed to hurricane and loop-current condition. The scatter was significant in the pre-model test computational results. In order to compare the computed results with results of model tests, a series of benchmark model tests were carried out. Based on the model tests results post-model test validation analysis and guidelines for ultra deepwater model tests and coupled analysis for deepwater structures were carried out. In this paper, the sequence of the DeepStar Theme Structure developments will be given briefly and the philosophy behind and the performance of the benchmark model tests will be presented.
