DREDGING OF THE BARRA GRANDE CHANNEL (RJ) AS A STRATEGY TO INCREASE THE OPERATIONAL CAPACITY OF THE PORT COMPLEX OF RIO DE JANEIRO
Abstract
The Port of Rio de Janeiro has increased its national relevance, standing out as the tenth in cargo handling in 2024 and the second in annual growth (ANTAQ, 2025). Despite this progress, operational restrictions related to waterway access persist, limiting the expansion of port capacity. This article analyzes the impact of these restrictions through a case study at a liquid bulk terminal in Guanabara Bay. Operational data from vessels were evaluated, including arrival, waiting, and stay times. The results indicate high average queuing and stay times, associated with draft limitations and nighttime navigation restrictions. The analysis demonstrates that dredging the Barra Grande Channel can significantly reduce waiting times and increase operational capacity, allowing the handling of larger vessels. It is concluded that interventions in waterway access infrastructure are essential for the competitiveness of the port complex.
