All eyes on the Deepwater Horizon

Mission-critical monitoring in difficult conditions

The Macondo prospect is an oil well in the Gulf of Mexico. The Macondo made world news in 2010 due to a blowout on the Deepwater Horizon drilling rig. The explosion caused an oil spill that had to be brought under control as quickly as possible to prevent further damage to the ecosystem. To say that this was a difficult mission is an understatement: action had to be taken immediately, but on the ocean that is not evident.

To plug the hole in the oil well, a Blowout Preventer (BOP) had to be installed deep underwater, preventing further leaks. Several teams and ships were deployed for this purpose, all of which needed good offshore communications and live monitoring to follow up this mission from minute to minute. In addition, reliability was of the utmost importance: if communications completely fail at any point, it has a huge impact on the progress of the mission.

Citymesh and connectivity go hand in hand, even in the middle of the sea.

In an extremely short time, Citymesh (formerly known as nCentric) was on standby. To manage the various parallel missions of the Thunder Horse remediation project, we provided two essential elements: first, communication between teams, commanders and the US government, and second, live monitoring of the subsea installation of the BOP. Thanks to the effort of our on-site experts and the deployment of the Nova Node, all deployed vessels received simultaneous and real-time access to HD images from various Remotely Operated Vehicles (ROV)

In doing so, the team was always ahead of all difficulties: possible obstacles, interference and the fact that the deployed teams were constantly on the move were taken into account. The images were reliably transmitted without interference to all parties involved.
