There is a potential for cumulative impacts to occur on the commercial fisheries receptors identified in the vicinity of the proposed East Anglia THREE project if all of the other potential developments, regulated activities and conservation areas considered are implemented. The likelihood of significant impacts occurring, however, depends largely on the operational practices of a given fleet and location and the extent of fishing grounds relative to other activities.


44.


With regards to cumulative effects associated with developments within the East Anglia Zone, under currently planned construction schedules it is not expected that there would be temporal overlap in the construction phases of the proposed East Anglia ONE and East Anglia THREE projects, and an overlap of short period between the offshore construction phases of the proposed East Anglia THREE and East Anglia FOUR projects. The effect of any overlap would be a short duration and of minimal spatial extent. Therefore it is not expected that there will be a cumulative effect associated with construction phases within the East Anglia Zone.

Transboundary impacts in relation to Dutch and Belgian fishing vessels are discussed within the assessment chapter.


30.2.9 Chapter 15 Shipping and Navigation 46.


The southern North Sea is an area of significant shipping and navigation activity. Shipping activity in the East Anglia Zone includes the passage of merchant vessels, ferries, fishing vessels, recreational craft, military vessels, and vessels engaged on specialist operations such as aggregate dredgers. The East Anglia THREE site is located between several shipping routes, and buffers between the site boundary and these routes have been identified and applied through consultation with relevant stakeholders to minimise potential disruption and risks to vessel safety.

The impact assessment required consideration of the marine geology, oceanography and physical processes, commercial fisheries and infrastructure and other users assessments.


48.


Following consideration of the outputs of the hazard workshop, desk top assessments and modelling of six different receptors identified within this chapter that had the potential to be impacted by the development of the proposed East Anglia THREE project, have been completed. The assessment identifies suitable mitigation for each impact during each phase of the proposed project lifetime to ensure that these are reduced to acceptable levels.
