In 1978 the Marine Structures Lab (LEN) was founded, the first laboratory of the Naval Architecture and Ocean Engineering Program (Peno), aimed at implementing an experimental technology to be used in vessel structures. In 1984,  LEN stablished a partnership with Petrobras for the development of methods for the assessment of the mechanical condition of the machinery installed in platforms, which was soon extended to the refineries and pumping stations of the company.

In 1998, LEN started being called Ledav and, ever since, it performs research projects involving monitoring and diagnostics of machines and structures, noise and vibration measurements in vessels and platforms, investigation of the causes of excessive vibration in machines and structures, measurement of combined efforts in axes and the analysis of turbomachines balance.

Ledav advances in such researches through the courses offered, the courses’ final projects and master’s degree and doctor’s degree thesis, with comparison between theoretical and numerical models and experimental results, whenever possible.

Some of Ledav customers are: Petrobras, the Brazilian Navy, shipyards, project companies, classifiers, sugar and alcohol plants, oil refineries, among others. Ledav adhered to the Integrated Management System of Coppe/UFRJ and is permanently implementing internal procedures aiming at improving the researches and the services provided.

The lab is linked to the Naval Architecture and Ocean Engineering Program.
