The Brazilian Navy sought to ensure the operational and structural safety of its fleet for an additional 15 years, maintaining efficiency and reliability under increasingly demanding technical and environmental conditions.
This project required a partner with proven technical capability, advanced expertise in naval engineering and structural modeling, and the ability to deliver detailed analyses and clear guidelines for repairs, maintenance, and long-term integrity management.
RINA won the public tender for the full execution of the project, conducting inspections, analyses, and technical reports aimed at extending the service life of multiple vessels in the Brazilian fleet. Our engineering team performed comprehensive structural integrity assessments, considering the ships’ original design criteria, structural stresses, corrosion, fatigue, and repair history.
Key activities included:
- Full 3D finite element structural modeling, carried out to ensure accuracy and reliability;
- Visual inspections, thickness measurements, and non-destructive testing, complemented by laboratory tests on samples;
- Development of advanced methodologies for corrosion prediction and fatigue monitoring;
- Integration of technical and historical maintenance data into a robust digital management system, enabling traceability and continuous integrity oversight.
Throughout the process, we ensured strict adherence to safety regulations for confined spaces and dry-docking operations, as well as compliance with national and international standards and Classification Society requirements.
More than a service provider, we acted as a strategic partner to the Brazilian Navy, combining science, engineering, and innovation to reinforce the safety and reliability of the national fleet for the next 15 years.
The project delivered a comprehensive set of technical reports, including the Initial Analysis Report (RAI), Structural Inspection Report (RIE), and Final Service Report (RFS), detailing structural conditions, critical fatigue and corrosion points, and recommended repair and monitoring actions.
In addition, Initial (PI) and Future Inspection Plans (PIF) were developed, outlining timelines, testing methodologies, and priority areas for monitoring, establishing a framework for continuous structural integrity management.
Among the most valuable outcomes were three validated methodologies developed by RINA:
- MAE (Structural Analysis Methodology)
- MPMC (Corrosion Prediction and Monitoring Methodology)
These serve as a technical and scientific foundation for future maintenance and repair decisions, supporting safe, cost-effective, and reliable operations for the Brazilian Navy.
