AUVs first entered the Oil and Gas market in the 1990s due to a requirement to solve challenges posed by deep water survey. In particular, ROV tether management systems were highlighted as a major technical hurdle. Nowadays, demand for AUV surveys is being fuelled by commercial and quality demands. The data quality and resolution that AUVs deliver are seen as the major contributing factors in de-risking projects, starting from the FEED stage.
AUV technology has developed to such a degree that since October 2012, DOF Subsea reliability figures of over 320 dives yielding +25000km of survey, delivered less than 4% downtime on 8 different vessels for 6 different clients and these figures are not isolated. Other AUV service providers can claim similar successes, testament to the major strides forward the AUV industry has made since the 1990s.
