Petrobras recently revealed the start of licensing for the Autonomous Underwater Risen robot Inspection (Auri), which was developed in partnership with PUC-Rio to carry out inspections in installations underwater. The machine is capable of identifying the maintenance needs of the flexible pipelines that transport oil from subsea installations to production platforms.

The first tests were carried out in the Campos Basin, in the state of Rio de Janeiro, and the process was successful in proving the effectiveness of Auri.
“Petrobras created a broad program to increase safety in diving operations, called the Diverless Synergy Program. This program introduced new systematics, methodologies and technologies to increase divers' safety. The results we have obtained are an example of how a culture of innovation and improvement generates value for the business, demonstrating that it is possible to produce more and more safely” revealed João Henrique Rittershaussen, development director of production.
The machine is controlled by a remote professional, who performs the inspection and all cleaning services in the flexible ducts. The tools used by Auri to perform such tasks were designed with the ability to move up to 360 degrees.
The tools used by the oil company are attached to a vehicle with remote operation, but Auri uses the ROVs only in the pipeline installation and de-installation processes, which will save over 1,300 hours of dive. The robot will also contribute to the safety of professionals, as it reaches a depth of up to 50 meters and can be used in adverse weather conditions.
