Software tool automates subsea data processing workflow
Danish software engineering specialist EIVA has released NaviSuite Workflow Manager, a new tool for automatic processing of large volumes of subsea data with minimum human intervention.
Workflow Manager is fully-configurable and facilitates automated and parallel execution of repetitive tasks such as applying tide and sound velocity profiles, cleaning data, correcting seabed heights across multiple surveys and exporting data in different formats. This not only ensures that the data is processed faster but, also, that crew time is more efficiently spent on error detection, interpretation and quality control.
Initial performance measurements on real-life data and workflow set-ups have been encouraging, with 50 hours of data processed in less than two hours. That is twenty-five times faster than many other methods which are able to process 1:1, i.e. one hour of data in one hour. This milestone was achieved with six AUVs continuously running in parallel and with all the data being processed by a single crew.
