Q: What are the three methods of offshore wind farm construction?

Q: A guyed tower uses cables spreading outward from sections of the tower to ground anchors for _________.
- simpler mounting pads
- stability
- rigidity
- gaining greater tower heights
- all of the above
A: all of the above

Q: The FAA requires lamps to be affixed to towers over a certain height.
- True
- False
A: True

Q: Wind farms can interfere with electromagnetic signals such as radio and TV broadcasts.
- True
- False
A: True

Q: When a 7460-1 form is filed, a required study from the FAA does not need to occur.
- True
- False
A: False

Q: Corrosion occurs more on like offshore wind turbines than onshore ones.
- True
- False
A: True

Q: _____ is used for the pads (base) of the large wind turbines.
- Steel disks
- Reinforced concrete
- Gravel
- Blocks
A: Reinforced concrete

Q: ________________ towers are used for large wind turbines. They are stacked in sections and are bolted together.
- Lattice
- Monopole
- VAWT
- Polar
A: Monopole

Q: A mast tower that is not guyed can be built very tall and will be rigid.
- True
- False
A: False

Q: Some smaller tubular as well as lattice and mast towers are raised into position by use of  _______.
- gin poles
- large cranes
- a pulleys and rope
- guy wires
A: gin poles

Q: Most large VAWT farms did not work out very well and have been since removed from service.
- True
- False
A: True

Q: Much of the larger foundations are below ground. Steel pilings are often drilled into the ground to further secure foundations to
rock for certain slightly unstable areas.
- True
- False
A: True

Q: On large wind turbines, a small lower-level channel is created to allow power cables to access pad transformers from beneath the
tower. This conceals the wire, but allows access for inspection and maintenance.
- True
- False
A: True

Q: The bottom tower section is bolted to the top of the pad by threaded anchors incased in the foundation’s ___________.
- concrete
- blocks
- base tie-offs
- base caps
A: concrete

Q: Some towers sections have the cables contained within them; others are installed on the ground or after construction.
- True
- False
A: True
