This is phase 1 of the norfold windfarm project. 30x2Mw turbines, locarted 3 km off the coast at Great Yarmouth. It is
of note that phase two is intended to be at a further distance so that visual
impact will be minimized of eliminated from the coast. [http://www.edp24.co.uk/Windfarms/asp/implications/Constraints_D2.asp#visual2ii]
12 Km off Dutch coast. 36 x 3 MW (Vestas v90 turbines)
How deep will they be?
The turbines will generally be built in relatively shallow
water - less than about 30 metres in depth.
How far out to sea will they be?
The Department of Marine has indicated that a minimum
distance of 5km offshore is appropriate. Shorter distances would need to be
justified. In other parts of
Is there a limit to how far out to sea
these can be built?
Although it is possible to build structures in water deeper
than 30m (for example the oil platforms in the

Deep water technologies involve attaching the tower to a floating platform instead of a monopole – this type of technology is well suited to being pioneered by the north east. Since available materials and skills are already existing here.

Kitesurfers travel at 15 to 30 Knots, thus they could potentially travel 1 Km offshore in a mere 60 seconds. It is therefore unlikely that kitesurfing could continue in this area following the contruction of the windfarm

The piles of the windfarm may effect the surf. Windsurfers and Kitesurfers should reasonably expect 1km of safe sailing area from the beach. Windsurfers and surfers regularly use the region of the beach from
The proposed wind turbines are 5 MW. These represent the largest so far developed. A working example of a 5 MW turbine is that of
These have a 120m tower with 61 m blades attached, giving a
blade span of 126 m and a ground to tip height of 183m. Thus 150 m in the scope

commissioned will be in the moray firth a distance of

Height reference: the NORTHERN LIGHT TOWER of the AECC is 45
m in height.
Turbines should be placed at least 2 Km offshore, i.e. the position of the first row. If the
second row was a further 600m offshore then the depth of the turbines would be
between 18 and 24m. 5 Mw towers are certainly capable of this depth.

“Local Issues
What opportunities are there/should there be for local community involvement in, and economic benefit from, renewable energy schemes?
Given the present Executive's pressure to ensure maximum development of wind farms there are few opportunities for local communities to benefit to any significant degree. Short term employment, for unskilled labour only, and grants by wind farm developers to local community councils to secure local support for their developments cannot be construed as benefits.
There is no long term economic benefit to local communities in the present renewable energy schemes proposed by the Executive.
There are, however, many disadvantages for the local community through loss
of tourism. It is reported that tourism in
The value of private property could be substantially reduced for those whose homes are located close to wind farm developments*9
We further believe that local communities have a responsibility for identifying their own measures for moving to renewable energy sources. Such an approach would create a higher degree of involvement and ownership within the community. However, as is proving the case with the large scale development of wind farms local communities often have little or no say in how such developments are taken forwards.

Offshore wind

Offshore wind farms offer the dual benefits of increased efficiency and reduced visual impact in comparison to onshore wind farms. Any adverse affects to human health from wind turbines would be mitigated by siting turbines offshore. This must surely be a positive desire. However, because they are more expensive to build than onshore wind farms, there is less profit for the developers and hence the current clamour to develop onshore sites.* 10. Despite having environmental problems affecting sea traffic, offshore technology is rapidly advancing thus enabling the construction of such sites as Scroby Sands. “
