Intervention AUV
Intervention AUV or I-AUV is a type of autonomous underwater vehicle. Its characteristic feature is that it is capable of autonomous interventions on the subsea installations, a task usually carried out by remotely operated underwater vehicles (ROVs) or human divers.
== Before I-AUVs ==
Basic maintenance as well as repairs were traditionally done by human divers equipped with the appropriate pressure-resistant suits. Such operations were burdened with a high dependency on weather and involved direct hazards on humans. Due to slow exhaustion of the shallow oil sources, the oil wells were installed in deeper water (>500m of depth). This made diver operation less feasible due to heavy suits and higher associated risks. Beginning in the 1980s, those duties were gradually taken over by ROVs which were reaching a status of a proven tool.
Both methods of intervention require mobilization of surface support vessel which is necessary either to supply and retrieve the divers or to deploy and control the ROV at work. The costs of maintaining such vessels or hiring them to complete an intervention are high (in the order of hundreds of thousands USD for a day of operation) and contribute significantly towards the operational expenses connected to running the field.
