Análise de projetos de montagem de turbinas eólicas

Abstract

With the expressive growth of wind energy in Brazil since 2011, the execution of wind turbine assembly projects, which is a stage of the wind farm implantation, which brings together fundamentals of machine design and operations with cranes, has been presented as an activity complex and difficult to execute. In the monitoring carried out in 2017 by the National Electricity Agency (ANEEL), in the projects under construction contracted by the ACR (Regulated Contracting Environment), only 36% are with the works according to the planned schedule. In this context, seeking excellence in wind turbine assembly projects is a matter of survival for the entrepreneurs in this market. This work aims to analyze the implementation phase of wind turbine assembly projects, considering the planning carried out according to the PMBOK (Project Management Body of Knowledge). The study analyzed a project of assembly of 15 wind turbines, considering the transportation and mechanical assembly of components. The methodology used includes exploratory and descriptive research, since it involves a bibliographical survey and systematic observation; documentary and field study, characterizing itself as a case study. Planned and accomplished in four steps. As a result, only 82% of the scope was executed within the planned time. The final cost of running the project was 5.5 times higher than planned. And, it took more time to finish the project, about 21% more than the planned schedule.
