On the Reliability of the Autosub Autonomous Underwater Vehicle

Abstract: As autonomous underwater vehicles (AUVs) enter operational service an assessment of their reliability is timely. Using the Autosub AUV as an example, several design issues affecting reliability are discussed, followed by an analysis of recorded faults. Perhaps contrary to expectations, failures rarely involved the autonomous nature of the vehicle.Rather, faults were typical of those that occur with any complex item of marine electromechanical equipment. A statistical analysis showed that the failure rate decre… Show more

“…As ocean monitoring becomes more dependent on undersea gliders it becomes imperative to have a risk informed process for managing the deployment of these vehicles. However, whilst the reliability of propelled autonomous underwater vehicles has been studied in detail [9][10] [11], to this date the only detailed analysis of undersea glider reliability based on independent user data is presented in [12]. In this paper the authors built a risk profile for five undersea gliders based on user data.…”

“…Experimental feedbacks and mission sequence analysis of unmanned mobile robots in the field have generally demonstrated that there is a huge lack of dependability when physical or logical failures occur [1,2,3,4]. Unfortunately, this limitation is an important bottleneck for the development of a real public- 10 oriented robotics that must efficiently deal with availability, reliability, safety and maintainability aspects.…”

“…The AUTOSUB AUVs of the National Oceanography Centre, Southampton have been analyzed with respect to reliability and risk associated to under ice operation (Griffiths et al, 2003, Griffiths and Brito, 2008). The reliability was derived by expert judgement based on the fault logs of the vehicle.…”
