Offshore specialist Subsea 7 operated a workclass ROV from Scotland to carry out work 9,400 km away off the coast of Brazil
The success of the project has proven the technology and capabilities developed by Subsea 7 can perform key inspection, repair and maintenance (IRM) tasks precisely and safely under remote control with the potential to increase operational flexibility.
“This was a major milestone for Subsea 7,” said ROV and autonomy manager Alan Gray. “The maturity of our remote piloting systems has been demonstrated here and shows how new technologies, alongside new ways of working, can lead to more sustainable operations. Subsea 7 has deployed remote piloting systems on ROVs in the North Sea region, but this demonstration was our first remote piloting operation conducted for Brazil.
The operations phase, which included pipeline inspection and light intervention tasks, was part of an ongoing contract to provide IRM services for Petrobras.
The project involved a remotely piloting an upgrade of the workclass ROV system on board an ROV support vessel. Real-time remote control was achieved via a secure, high-speed, communications link to Subsea 7’s Aberdeen Onshore Control Centre. Subsea 7 also has two onshore control centres in Stavanger, Norway.
