Brazilian state owned oil and gas company Petrobras has initiated two tenders for geophysical studies as part of its offshore wind pilot project off the coast of Rio de Janeiro.

These surveys aim to assess the feasibility of developing wind energy infrastructure in the region, marking a significant step in Brazil’s renewable energy transition.

Geophysical Survey in São João da Barra

The first tender focuses on acquiring and processing geophysical data in the ultra-shallow waters near São João da Barra, located in the northern part of Rio de Janeiro state. The scope of work includes electrical tomography, bathymetric and topographic surveys to a depth of approximately 10 meters, covering an area of about 1.5 square kilometers.

These techniques will provide detailed subsurface information essential for evaluating the area’s suitability for offshore wind installations.

Geotechnical Survey in shallow and ultra shallow waters

The second tender involves the acquisition of geotechnical data in shallow and ultra shallow water and beach environments. This survey will complement the geophysical study by providing critical information on soil conditions, which is vital for the design and construction of wind turbine foundations.

The Port of Açu, situated near São João da Barra, is a strategic location for the offshore wind project.
Its proximity to the proposed survey area and existing infrastructure makes it an ideal site for supporting offshore wind operations.

The port’s development aligns with Petrobras’s commitment to integrating renewable energy projects into Brazil’s energy landscape.

Petrobras’s launch of these geophysical and geotechnical survey tenders represents a significant advancement in Brazil’s offshore wind energy initiatives.

By leveraging its expertise in offshore operations and collaborating with governmental and environmental agencies, Petrobras is positioning itself as a key player in the transition to renewable energy in Brazil. The outcomes of these surveys will be instrumental in determining the feasibility and design of future offshore wind projects in the region.
