In the parallel universe of offshore construction, it is the CAESAR data model that holds sway rather than the upstream's Epicentre, although the CAESAR model is also confusingly termed POSC/CAESAR. Significant progress has been claimed by IBM in the difficult task of migrating legacy data to the CAESAR model. Recognizing that using the CAESAR data model is not for the faint hearted - requiring considerable expertise in manipulating the exotic Express-X data modeling language, IBM Norway have automated the process of converting data from existing systems to the CAESAR data warehouse. The business driver behind such data modeling is to offer all involved in the construction and maintenance of the platform access to the same validated dataset. On Norway's pioneering Varg, Asgard and Visund (VAV) project, proponents anticipate a reduction in the time needed to construct and certify an installation of up to six months.
