Brazils energy matrix plays a significant role in renewable energies, particularly hydroelectricity. However, diversifying with sources such as wind energy is essential for sustainability and energy security. Offshore wind energy emerges as a promising alternative, facing specific challenges in Brazil, especially related to the high and uncertain costs of logistical operations. The main obstacles to implementing offshore wind projects include uncertainties in pre development, production, installation, operation, and decommissioning costs. These stages involve factors such as permitting, material procurement, turbine transport and installation, maintenance, and asset removal with proper environmental restoration. The objective of this work is to analyze the offshore wind sector scenario and study the influence of uncertainties associated with logistical investment costs in offshore wind energy projects globally, with a focus on implementation in Brazil. This approach allowed the identification of the main sources of uncertainty and propose strategies to mitigate them, contributing to the economic viability and sustainable expansion of offshore wind energy in Brazil.
