1. Mechanical and Industrial EngineeringWind Energy Center University of Massachusetts Hull Offshore Wind Project: Next Steps J. F. Manwell, Prof. and Director Wind Energy Center (a.k.a Renewable Energy Research Laboratory) University of Massachusetts Amherst May 12, 2011

2. Mechanical and Industrial EngineeringWind Energy Center University of Massachusetts Status of Original Project No fatal flaws Economics difficult Transforming project to mixture of energy production, demonstration, research and education most interesting 2

3. Mechanical and Industrial EngineeringWind Energy Center University of Massachusetts Options Build on progress to date Monitoring platform with cable to shore Pre-set foundations for testing offshore wind turbines Some number of primarily energy producing turbines Integrate Hull project with proposed Massachusetts Offshore Wind Energy Center 3

4. Mechanical and Industrial EngineeringWind Energy Center University of Massachusetts Research Platform Consider FINO platform (Germany) as model Environmental studies Meteorologic/oceanographic –LIDAR, ADCP, RADAR Transformer/switch gear for any wind turbines Cable (power and data) to shore 4

5. Mechanical and Industrial EngineeringWind Energy Center University of Massachusetts Turbine Test Platform Large gravity structure in shallow water (e.g. Harding Ledge) could allow various turbines to be installed, tested and removed Power/data to research platform 5

6. Mechanical and Industrial EngineeringWind Energy Center University of Massachusetts Possible Research Projects Permitting/Feasibility Stage –Continued wind and wave monitoring –Support structure studies –Cost estimation –Environmental monitoring –Public acceptance 6

7. Mechanical and Industrial EngineeringWind Energy Center University of Massachusetts Possible Research Projects(2) Studies during construction –Continued wind and wave monitoring –Environmental monitoring –Public acceptance studies –Documentation of the process 7

8. Mechanical and Industrial EngineeringWind Energy Center University of Massachusetts Possible Research Projects(3) –Studies during operation Structural response Wind and wave monitoring Environmental monitoring Energy production Turbine wake studies (if multiple turbines) Air quality benefits Operation and maintenance Electrical studies Economic assessments Public acceptance Policy studies 8
