(f) a cable specification and installation plan following consultation with the relevant statutory nature conservation body, to include—

(i) technical specification of offshore cables, including a desk-based assessment of attenuation of electro-magnetic field strengths, shielding and cable burial depth in accordance with industry good practice;

(ii) a staged cable-laying plan for the Order limits, incorporating a burial risk assessment to ascertain suitable burial depths and cable-laying techniques;

(iii) a scour protection management and cable protection plan providing details of the need, type, sources, quality and installation methods for scour protection and cable protection; and

(iv) details of the methodology and extent of post-lay surveys, to confirm burial depths; and

(g) a written scheme of archaeological investigation in relation to offshore areas within the Order limits in accordance with Chapter 18 Appendix B of the environmental statement, industry good practice and after discussions with English Heritage to include—

(i) details of the responsibilities of the undertaker, archaeological consultant and contractor;
