The document discusses floating windmills and their potential as a renewable energy source. It provides details on how floating windmills work using a semi-submersible floating hull structure that supports the turbine. The advantages are discussed as being a clean renewable source that reduces dependence on fossil fuels and decreases emissions. Challenges include the difficulty of installing and maintaining the windmills in water. The conclusion is that floating windmills have great potential to become a major energy source in the future.

2. INTRODUCTION

3. Wind results from the air In movement. Regardless of the
breeze's intermittent nature, wind designs at a specific site
remain strikingly steady step by step.
The breezes additionally will in general blow all the more
reliably and with more prominent strength over the outside
of the water where there is a less surface drag.
 At a tallness of 60m they might be 30-60% higher due to
the decrease In the drag impact of the world's surface.

4. How Floating windmill work:
 floating wind turbine is a single
point mooring system technology.
 a semi-submersible floating hull
with a 4 masts pyramidal
structure. The structure supports
the turbine by 2 upwind and 2
downwind masts. It gives more
clearance for the blades and a
distributes stress.

5. Floating Design Concepts:

6. ENERGY PRODUCTION FROM
WINDMILL:
1. The wind blows on the blades and makes them turn.
2. The blades turns a shaft inside the nacelle (the box at the top of the turbine)
3. The shaft goes into a gearbox which increases the rotation speed enough for...
4. The generator, which uses magnetic fields to convert the rotational energy into
electrical energy. These are similar to those found in normal power stations.
5. The power output goes to a transformer, which converts the electricity coming
out of the generator at around 700 Volts (V) to the right voltage for distribution
system, typically 33,000 V.

7. ADVANTAGES:
 The advantages of an underwater windmill include the following.
 Less maintenance and gives more lifetime
 The Floating windmill uses Wind energy and this is a clean & renewable energy
source
 Wind energy is totally renewable & it doesn’t generate emission
 It is an emission-free power source
 Decreases the dependence on fossil fuels.

8. DISADVANTAGES:
 The disadvantages of underwater windmills include the following.
 Installation in water is very difficult.
 To avoid the corrosion. it must be coated.
 Difficult to maintain.
APPLICATIONS:
 The applications of underwater windmills include the following.
 Windmills are used to remove power from the energy of wind.

9. CONCLUSION:
It can be concluded from the various researches and
detailed information about the various parameters on
underwater windmill in this article, that it has a great
potential to be become one of major source of energy in
upcoming future.
