Back2Base is a set of technologies and processes that enable large survey data files to be reliably and economically transferred from offshore survey vessels to a terrestrial survey office and client, via internet links such as satellite or mobile broadband and WiFi.

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.

Data Packaging Example:

The example below shows the reduction in file size typically obtained from the Back2Base process for MBES survey data

Example Data Set: File Size
Raw Data (5 min MBES calibration line) 680 Mb
Packaging: 49 Mb
Compression: 4.8 Mb
  • More timely delivery of final survey deliverables to the client.
  • Continuous monitoring and QC of survey data.
  • Access to Fugro’s subject matter experts around the world.
  • Prompt interpretation/QC of data by Fugro reporting data centres.
  • Client access for remote monitoring/review of survey data, improving project planning, execution and QC of project data.
  • Timely decision making based on quicker access to survey data.
  • Optimisation of survey crew size on suitable projects, reducing vessel POB, HSE exposure and logistical requirements for personnel mobilisation.
