Risk and Reliability Management of Marine Autonomous Systems within the UK’s National Marine Equipment Pool

The MARS group at NOC develop and operate one of the world's largest fleets of Marine Autonomous Systems as part of the UK's National Marine Equipment Pool. The need for reliability processes arises from needing to meet science/mission objectives, deliver value for money, keep systems and operators safe and reduce risk to reputation. This first requires appropriate data collection processes, providing data to quantify and inform decisions, mitigation and action. Further analysis of faults and their surrounding circumstances can then be used to create a historical view of factors affecting mission success. In this work, data originating from vehicle command and control systems and from a new unified fault recording and management system have been aggregated to build dashboards and reports that meet key stakeholder requirements. The dashboards are used to visualise a timeline of recorded faults, to plot multi-vehicle engineering and science parameters , and to display warnings, oddities and errors automatically logged by the vehicle. Fault reports are automatically generated to create an overview of the fault management process over the last 30 days, as well as a list of pending critical faults. Further work will use fault data to create a maintenance planning dashboard, linked to inventory data to monitor components throughout their life cycle.
