ENRON WIND 3.6 OFFSHORE: EXAMPLE FOR THE NEXT GENERATION OF OFFSHORE WIND TURBINES

摘要

Offshore wind energy technology is developing rapidly. New giant machines ranging from 3 to 5 MW are forthcoming. Design requirements with respect to the demanding marine environment are discussed, i.e. integrated design of offshore wind farms, design for reliability, availability, maintainability and serviceability, smooth grid integration, logistics and offshore installations. The Enron Wind 3.6 offshore and its onshore variant the Enron Wind 3.2s are introduced and analysed with respect to these design requirements. Particular emphasis during the development was put on a robust and proven machine concept and reduction of operation and maintenance cost through many features e.g. an innovative internal crane system for the exchange of all main components. Furthermore support structure options and the electrical system are discussed. A prototype will be erected in April 2002 and a first sea-based project is aimed for in 2003.
