Paragraph 2 Design parametersI1
England and Wales
The wind turbine generators to be constructed as part of the authorised development must be located within the area shown on the works plan.
No part of any wind turbine generators to be constructed as part of the authorised development shall extend beyond the Order limits.
The authorised development must be constructed in accordance with the parameters assessed in the environmental statement and set out in Table 1.
The F1undertaker may not undertake Work No. 1 in a manner which would give rise to any materially new or materially different environmental effects to those identified in the environmental statement based upon the maximum design scenarios set out in Table 3.5 of the environmental statement.
References to the location of an offshore surface structure in Table 1 is a reference to the centre point of that structure.
In the event that driven or part-driven pile foundations are proposed to be used, the hammer energy used to drive or part-drive the pile foundations must not exceed—
4,400kJ in respect of pin pile foundations at up to 16 locations; and
3,000kJ in respect of any other foundations.
