Unprecedented operation with New Panamax ship places the Port of Rio at a new logistical level after the expansion of the operational draft and million-dollar dredging in the access channel of Guanabara Bay, allowing the arrival of larger vessels on international container routes.
In an operation considered strategic for container navigation in Guanabara Bay, the Port of Rio de Janeiro received, on May 14, 2026, the first 366-meter-long ship in its history, consolidating a new stage for the terminal’s maritime access.
Docked at the MultiRio terminal, the container ship MSC Katrina arrived in Rio after the completion of the dredging of the Main Channel, an intervention that improved the port’s operational conditions and allowed the entry of larger vessels on international routes.
To enable the operation, PortosRio invested R$ 163 million in modernizing the waterway infrastructure, increasing the minimum depth of the access channel from 15 meters to 16.2 meters and authorizing the expansion of the operational draft to 15.30 meters.

With 366 meters in length, 48.40 meters in beam, and the capacity to transport 14,131 TEUs, the MSC Katrina is part of the New Panamax class, a category aimed at transporting large volumes of cargo on international maritime lines.
Before arriving at the Port of Rio, the vessel had passed through the Port of Suape, in Pernambuco, and subsequently proceeded to the Port of Santos, in São Paulo, as part of a national route linked to container movement.
Port of Rio expands operation for New Panamax ships
By receiving the MSC Katrina, the Port of Rio implemented a new operational configuration aimed at large ships, which depend on adequate depth, maneuver planning, and integration between the terminal, piloting, and port authority.
In addition to the nautical structure, operations of this size require compatible signaling and strict safety control, as any restriction in the access channel can compromise the movement of vessels with high cargo capacity.
In this scenario, the draft — the distance between the waterline and the lowest part of the hull — becomes crucial to determine which ships can access a particular terminal without compromising navigation safety.
As the size of vessels and the volume transported increase, so does the need for depth in the channel, a factor considered strategic for ports competing for space on international container routes.
The dredging approval by the Rio de Janeiro Port Authority took place on April 1, 2025, and authorized the terminal to operate vessels up to 366 meters within the new parameters defined for the main channel.
Channel dredging increases operational capacity
Responsible for changing the operational limit of the port, the dredging of the Main Channel reduced historical restrictions for larger vessels and made room for operations compatible with the standards required by New Panamax class ships.
Before the intervention, ships with dimensions similar to those of the MSC Katrina needed to operate under more restrictive conditions, mainly due to depth limitations in the maritime access to the terminal.
With the new minimum depth of 16.2 meters, the Port of Rio began to offer a greater safety margin for large-scale operations, as well as increasing its competitiveness compared to other terminals focused on international container transport.
In global maritime lines, shipowners tend to prioritize ports capable of receiving larger vessels, as high-capacity ships allow for more cargo to be transported per trip and improve the logistical utilization of routes.
In practice, the docking of the MSC Katrina at the MultiRio terminal confirmed the operational capacity of the Port of Rio to receive New Panamax ships and reinforced the terminal’s presence on the national route between Suape, Rio de Janeiro, and Santos.
Operation strengthens port logistics in the Southeast
Important for the movement of containers, vehicles, and project cargo, the Port of Rio de Janeiro occupies a strategic position in the logistics of the Southeast Region and increases its relevance by starting to operate vessels with greater capacity.
With the expansion of the operational draft, shipowners, importers, exporters, and logistics operators now have new alternatives for cargo distribution in an area close to industrial hubs and large consumer centers.
In a segment dependent on scale, predictability, and nautical safety, depth limitations tend to directly affect the scheduling of maritime lines and the commercial attractiveness of certain port terminals.
On the other hand, ports prepared to receive large ships tend to gain space on international routes, especially in operations that require greater logistical efficiency and cost reduction per trip.
The operation of the MSC Katrina also reinforces that the performance of a terminal does not depend solely on docks, yards, or handling equipment, but mainly on the quality of the waterway access used by the vessels.
In Guanabara Bay, the presence of a 366-meter ship symbolizes a significant operational change for the Port of Rio, which now competes for space in a scenario marked by the advancement of increasingly larger vessels in international maritime trade.
