Getting survey data from the field to the client in a timely manner has previously had to rely on the vessel completing the work and returning to port, but not any longer. Fugro has developed a process for packaging survey data and delivering it to a terrestrial data centre, for processing and delivery to the client whilst survey operations continue uninterrupted.
As a result, Back2Base optimises the complement of onboard data processing staff, reducing cost and HSE exposure.
Data are organised and packaged into highly compressible formats using proprietary techniques and then queued for automatic transmission on a line-by-line basis or set time interval. In the destination office, data are automatically downloaded to the appropriate centre, where they are decompressed, unpackaged and made available for processing or quality control. The digital data can then be downloaded by the client.
