Portos do Paraná is preparing to demolish a small part of the Pedra da Palangana to increase navigation and environmental safety. Removing the shallowest points of the underground rock complex minimizes the risk of stranded ships and environmental disasters. Less than 12 meters in the most critical stretch, the current depth is expected to increase to 14.6 meters. Six parts of shallow points of the rock mass will be removed, totaling 22,300 cubic meters in volume. The smallest of them is 361 cubic meters and the largest 8000 cubic meters. The rocks are part of the complex known as “Pedra da Palangana” and are located in the main access channel to the Port of Paranaguá, the Galheta Channel, just in front of the Container Terminal. Once the work is completed, the company will carry out a category A bathymetry, which measures the depth of the area and is used to ensure the safety and efficiency of vessel traffic. The results of this measurement will be forwarded to the Navy for validation and determination of a new draft, which corresponds to the water height necessary for the ship to float freely.
