Powering operational EFFICIENCY
Transitioning to remote survey operations, Exail helps companies and institutes worldwide gain in operational efficiency, while supporting the sustainable growth of the oceans.
24/7 operations
Deploying a fleet of DriX USVs offering outstanding seakeeping and speed capabilities, Exail can operate 24/7 while keeping downtime to a minimum, even in severe weather conditions. These seakeeping and speed capabilities further allow Exail to increase seafloor mapping rate with no compromise on data quality, drastically reducing operational costs.
Force multiplying
MULTI-USV operations
Exail team of surveyors can deploy multiple DriX USVs as an efficient and easy way to optimize your survey efficiency. Multiple DriX can either be fitted with the same sensors and be used on the same survey zone, or they can perform separate missions using different sensors.

Unrivaled data quality
DriX offers optimum conditions for high quality data acquisition: sensors located 2 meters below the surface, in a highly reduced-noise and bubble-free environment.
Combined with the DriX USV outstanding line keeping, and state-of-the-art acquisition sensors (MBES, INS, USBL, SBP, velocity probes…), Exail teams of surveyors can help you collect even higher data quality than with traditional assets. This in turns translates into drastically reduced post-processing phases.
Past operations using the DriX Uncrewed Surface Vessel have a data cleaning rate reduced up to 8 times depending on client or mission scope.
