18.3.3 Embedded mitigation 11.


The location of the East Anglia THREE site and offshore cable corridor has been selected to minimise potential interaction with neighbouring infrastructure. As outlined below the project is:


   


12. Located outside any existing active oil and gas wells;


Located outside any areas licensed for dredging and aggregate extraction; Located outside any known Ministry of Defence (MOD) danger areas; and Located outside any known military practice and exercise areas (PEXA).


The East Anglia THREE site has been located to avoid existing telecommunication and transmission cables. The East Anglia THREE offshore export cables would be aligned so that where there are crossings with other cables and pipelines (for example the Greater Gabbard and Galloper Offshore Windfarmcables) they would be as near as practicable to a 90o angle.


13. Owners and operators of other infrastructure (including oil and gas developers, dredging companies and electrical and telecommunication cable operators) are, and will continue to be, consulted by EATL and legal agreements would be put in place where required. These may relate to setback distances or cable crossing agreements should the project achieve consent. Cable crossing agreements would be agreed in the outline design and would consider:


 


Location of any cable crossing; Any cable bridges;


 Materials used for protecting the crossing;  Method of installation;  Methods for maintenance; and 


Separation distances. 14.


In terms of reducing the risk and threat of unexploded ordnance (UXO) the following embedded mitigation would be implemented:





An Enhanced Risk Assessment would be required to ascertain the requirements for geophysical survey coverage of site investigation at specific
