The giant offshore wind power vessel, which is about 150 meters high, enters the setup phase

The Fukushima Revitalization Floating Offshore Wind Farm Empirical Research Project, which began in 2011, will build the world's first project
with three wind power plants and one substation facility.
Finally, the fourth power station will have a power generation capacity of 5MW and will eventually be set up off the coast of Fukushima
.

In June, the offshore wind power plant named "Fukushima Hamakaze" was fully equipped and operated
on the coast of Awaji Island, Hyogo Prefecture.
Towing began off the coast of Fukushima at 8:30 a.
m.
on July 2
.
The windmill rotates with a diameter of 126 meters and the highest point of arrival starts from the surface of the water to 150 meters
.
The windmill is supported
by hexagonal floating structures known as "Advanced spar".

Offshore wind power plants off the coast of Awaji Island sail slowly 3~4 nautical miles (5-7 km/h) east of the Pacific Ocean
.
If you drive according to the plan, you will pass the coast of Ibaraki Prefecture in the morning of the 8th, and the Onahama Coast of Fukushima Prefecture in the afternoon, and arrive at the installation site
at 10:30 p.
m.

Of the three offshore wind turbines already operating off the coast of Fukushima, two were initially assembled in Tokyo Bay and towed off the coast of Fukushima
.
Three in front and one in the rear, for a total of 4 tugboats, and three guard ships
can also be equipped around the perimeter.

The four offshore wind power plants on the coast of Fukushima have a power generation capacity of 14MW, the largest
in the world in terms of floating volume.
The utilization standard of offshore wind power equipment is expected to reach about 30%, and the annual power generation will reach 36.
8 million Kwh
.
If converted into the electricity consumption of ordinary households, it is more than 10,000 households
.

When this large amount of power is transmitted 20 kilometers from the coast of Fukushima Prefecture, one of the four will be used as intensive power for substations
.
During operation, the two power generation facilities and substation facilities are connected by submarine cables, and from the substation equipment to the land in Fukushima Prefecture, they are connected
by submarine cables.

After the "Fukushima Hamaze" arrived at the site, the position of the equipment did not move, and the mooring chain went down to the bottom of the sea, entering the stage of cable laying engineering
.
According to the schedule, if there is no preparation, the laying work will begin on August 1 and is expected to be completed
on September 2 in one month.
If the substation equipment is connected by submarine cable, the trial operation will begin by adjusting the operation
.

In the case of the 7MW Fukushima Fresh Air, it takes about three months from the completion of cable laying to the start of trial operation
.
If the 5MW Fukushima Fresh Air begins laying cables in early September, trial operation
will begin in mid-December.
During the year, the world's largest floating body will enable offshore wind farms to be fully activated
off the coast of Fukushima.

In order to realize the world's most advanced offshore wind farm, we have started to develop a new energy industry
in terms of revitalizing Fukushima.
The subsea equipment does not have a fixed floating offshore wind power generation, and will control the shaking through waves and winds to ensure stable operation
.
For this reason, if the structure of the floating parts of the three wind power plants is changed, the power generation and safety will be tested
comparatively.

In addition, the Advanced spar type adopted by the "Fukushima Hamaze" will control shaking
in a two-stage combination through a hexagonal structure.
In Section 2, the lower structure is larger, measuring 51 meters
.
This massive structure sank 33 meters underwater, supporting the windmill structure
.

For the 2MW Fukushima Miku, which has been in continuous operation since November 2013, the actual equipment utilization rate in the first two years averaged 28.
7%.

Although the standard value of 30% for offshore wind power was not received, it increased almost as expected
.
With 7MW and 5MW figures, floating offshore wind power is expected to take a huge step forward
in the future.
