The Port of Rio de Janeiro has just activated the transceivers of the Automatic Identification System for Vessels with Aid to Navigation (AIS AtoN) of the three Submersible Articulated Buoys (SAB) in the Cotunduba Canal. This is the main waterway access for large ships to the Port of Rio de Janeiro.

With the AIS AtoN devices activated, a modern nautical signaling has become part of the Mobile Maritime Service, increasing the safety of navigation.

The transceivers transmit virtual markers that indicate to the ships the exact position of the SAB, with a precise delimitation of the channel, facilitating the maneuvers in the area reducing the risks of accidents. The devices have the most modern AtoN design, with high resistance to shock, vibration, temperature, water, winds and UV rays.

Once this stage was completed, the entire implementation of the Cotunduba Canal’s new mark project was completed with great investment in technology. The intention is to promote and enhance safety and efficiency of navigation of large ships, thus enabling an increase in the port operations, mainly for container terminals.

From April to the end of 2020, the first two phases of the ramp-up of experimental nighttime maneuvers were carried out. Now, a 3rd phase is underway, involving maneuvers of container ships from 306 to 335m in length (LOA).
