Ocean Energy in Brazil

• Availability of resources associated with all ocean sources

(wave, tide, current, temperature gradient, salinity gradient).

• Need of monitoring resource technical potentials.

• R&D activities associated with prototype deployments.

• Comparative advantage due to the recognized leadership in

deepwater technology for the oil&gas industry.

• Design, construction, installation and maintenance could benefit

from the outstanding field experience for oil&gas.
