Near shore operations, which allowed the AUV to work in as shallow as 2m water depth, totaling 571km of pipeline with 1 pass each side (1,142km of AUV track-line). Twenty platforms and subsea assets were also surveyed. Survey duration was 27 days during the winter; including mobilization and demobilization. Experienced less than 2% operational AUV downtime and only experienced 18% downtime due to the winter weather associated with Launch and Recovery. On a pipeline per kilometer basis, AUV surveys may be less than 50% the cost of a ROV survey.
