Subsea Production Test Centre is focused around fluid flow and production systems. This would take the form of an offshore simulated field. It is considered as an underwater production system exporting to an indoor flow loop complete with a multiphase, re-circulatory pumping station. In principle installation would be conducted in a dry environment and on completion could be flooded to create environmental testing. Such a facility could be used to test subsea production systems and subsea factory with realistic production conditions. It could also be utilised for SIT, FAT and qualification demonstration The dry dock could permit realistic SIT with ROV interaction.
