Potencialidades do uso de inland enc na hidrovia Paraná-Paraguai

Abstract

This work focuses on studying the feasibility of implementing a new model of Inland Electronic Navigation Charts (IENC) for river navigation in Brazil, taking into consideration the issues surrounding the production of physical (paper) charts, especially those used in inland navigation. Out of the 564 charts planned in the Brazilian Nautical Cartographic Plan (PCNB), 416 are dedicated to rivers, accounting for 73% of the total. Therefore, the study was limited to the Paraguay-Paraná Waterway (HPP) due to its international consecutive river nature and regional importance. The economic and development potential of navigation in this region was evaluated, drawing reference from international cases of similar waterways such as the Rhine River and the Danube, in order to compare how nautical charts are used in these regions. To obtain indicators allowing for the assessment of the feasibility of the new IENC model for the HPP, and potentially for all of Brazil, a comprehensive review of the regulations applied to the waterway was conducted, comparing it with maritime regulations. It was observed that the requirement for electronic charts applies to vessels with a Gross Tonnage (GT) greater than 100 in the HPP, representing a significant number of vessels in the region. Possible subsequent states were also identified for hypothetical cases of weaknesses increasing or emerging, which could affect the utilization of certain opportunities. This suggests the need for treatment to avoid the current situation transitioning to a "growth" state, where the product in question would not succeed due to weaknesses that prevent the exploitation of existing opportunities. This could eventually lead to a critical "survival" situation with the strengthening or emergence of greater threats, such as resistance from traditional river pilots to the adoption of new navigation methods and equipment. In conclusion, the studied product exhibits high potential for implementation due to its versatility in the HPP and the large number of users demanding its use in this waterway. Its high acceptance is a positive sign, and its implementation could significantly reduce the physical production of paper nautical charts nationwide, aligning with the transition to the digital era and the frequent updates required due to the constantly changing nature of the river. Furthermore, this action could make the HPP an international reference, enhancing navigation attractiveness and safety for both national and foreign vessels, potentially establishing a standard model for navigating this waterway, moving toward the adoption of the e-Navigation concept with the new S-100 standard products.
