Offshore Wind Energy


Quiz Questions

1.Wind sensors can detect the optimal direction for the turbine to point, allowing the turbine’s yaw controller to turn the blades into or away from the wind.
True
False
2. Each turbine has a generator that converts the mechanical power of the blades in motion into electricity which is then transmitted through subsea cables. The service life of a wind turbine is at least 20 years.
True
False
3.Offshore wind turbines typically generate more energy per hour than land based turbines due to their larger size and higher wind speeds.
True
False
4.A monopole base is a single column, 6 meters in diameter and is installed in water up to 30 meters deep.
True
False
5.According to the map on page 6, the best offshore wind resources in US waters are along the North and Mid Atlantic coast, in the Great Lakes and off the coast of the Pacific Northwest.
True
False
6.The water on the Pacific Coast becomes deeper much closer to the shore compared to the East Coast, making offshore wind development more challenging. However the Pacific Coast has the potential for high capacity offshore wind turbines.
True
False
7.Turbines like any large structure, can cause blockage or clutter interference with surveillance radars and electromagnetic systems.
True
False
8.Offshore wind farms are more _________ to build and maintain than onshore wind farms due to the higher cost of larger turbine structure, offshore turbine foundations and sea transmission cables.
Cheaper
Expensive
9.The foundations of turbines can function as artificial reefs for marine species.
True
False
10.Offshore wind turbines are designed to slow down or turn off in severe weather, such as when winds exceed 50 miles/hour. Wind farms can be built and designed to withstand winds exceeding 150 mph, a category4 hurricane.
True
False
