Upgrading the existing diesel powered pumps to gas turbine powered pumps required extensive, accurate, as-built data of this installation. A team of 2 Offset engineers spent 11 days offshore collecting survey and photographic data of 4 modules and the jacket cap. The 3D CAD modelling took a further 60 office based man days to produce using Offset’s in-house model management technology, Magan and was cross referenced with existing P&IDs, delivered in AVEVA PDMS format.
