  5. Design Changes - onshore and intertidal • Selection of final substation location and increase in height of substation structures • Amendments to cable landfall location and working corridor width in salt marsh • Realignment of the onshore cable route, inclusion of a section of cable connecting into the NGET substation, an additional cable spur to connect the export cable into the Project substation, and identification of specific working areas and access routes/points

  6. Design Changes - offshore • Increase in monopile foundation diameter from 8m to 9m • Addition of suction caisson foundation to jacket structures supporting wind turbines • Increased burial depth for inter-array cables • Changes to location of offshore export cable corridor • Inclusion of 8MW turbine within design envelope (no change in maximum dimensions of turbines)

  7. Design Changes - Consultation • Community consultation event, Middleton Parish Hall, 25th February 2013 • Design changes memorandum circulated to S42 and S44 consultees 28th February 2013 • Document placed on website, and notification sent to all S47 consultees 4th March 2013
