Development area The area comprising the Indicative Onshore Development Area and the Offshore Development Area East Anglia TWO project The proposed project consisting of up to 75 wind turbines, up to four offshore electrical platforms, up to one offshore construction, operation and maintenance platform, inter-array cables, platform link cables, up to one operational meteorological mast, up to two offshore export cables, fibre optic cables, landfall infrastructure, onshore cables and ducts, onshore substation, and National Grid infrastructure. East Anglia TWO windfarm site The offshore area within which wind turbines and offshore platforms will be located. Horizontal directional drilling A method of cable installation where the cable is drilled beneath a (HDD) feature without the need for trenching. Inter-array cables Offshore cables which link the wind turbines to each other and the offshore electrical platforms. Landfall The area (from Mean Low Water Springs) where the offshore export cables would make contact with land, and connect to the onshore cables. Monitoring buoys Buoys to monitor in situ condition within the windfarm, for example wave and metocean conditions. Offshore cable corridor This is the area which will contain the offshore export cable between offshore electrical platforms and landfall jointing bay. Offshore development area The East Anglia TWO windfarm site and offshore cable corridor (up to Mean High Water Springs). Offshore electrical infrastructure The transmission assets required to export generated electricity to shore. This includes inter-array cables from the wind turbines to the offshore electrical platforms, offshore electrical platforms, platform link cables and export cables from the offshore electrical platforms to the landfall. Offshore electrical platform A fixed structure located within the windfarm area, containing electrical equipment to aggregate the power from the wind turbines and convert it into a more suitable form for export to shore. Offshore export cables The cables which would bring electricity from the offshore electrical platforms to the landfall. Offshore infrastructure All of the offshore infrastructure including wind turbines, platforms, and cables. Construction, operation and A fixed structure required for construction, operation and maintenance platform maintenance personnel and activities. Offshore platform A collective term for the offshore construction, operation and maintenance platform and the offshore electrical platforms. Platform link cable An electrical cable which links one or more offshore platforms. Safety zones A marine area declared for the purposes of safety around a renewable energy installation or works / construction area under the Energy Act 2004. Scour protection Protective materials to avoid sediment being eroded away from the base of the foundations as a result of the flow of water.

A preliminary assessment of the landscape receptors in the study area has been undertaken using zone of theoretical visibility (ZTV) analysis (Figure 28.17) and site survey, to identify which of the landscape receptors are likely to be affected by the construction and operation of the offshore infrastructure. This preliminary assessment is presented in Table A28.1 and Table A28.2 below, which identifies the landscape character types (LCTs) and landscape designations that have the potential to undergo significant effects as a result of the construction and operation of the offshore infrastructure and require to be assessed in full; and those that do not have potential to undergo potential significant effects that can be scoped out of further assessment.
