East Anglia THREE– Navigation Risk Assessment

potential to create a cumulative effect with shipping and navigation receptors. This is considered in conjunction with work undertaken as part of The Crown Estates (TCE) into cumulative (and in combination) impacts associated with offshore wind developments in 2012 (TCE, 2012) which considered the screening of marine activities by area.
28.1.1 Reduction in available sea room for oil and gas exploration and infrastructure
465. Although it is noted that oil gas blocks (Section 7.6) have been licensed which overlap with the proposed East Anglia THREE site, no scoping work has yet been carried out by the licence holders so as to allow assessment of cumulative impacts to be undertaken. The proposed East Anglia THREE site is within UKCS Block 53/9, 53/10, 53/14, 53/15, and 54/6a. All of these blocks are currently licensed for oil and gas development by the operator Jetex Petroleum UK Ltd. and were licenced in the 27th round of licencing. There are also two plugged and abandoned wells within the East Anglia THREE site. Should any works be considered pre or post consent as per planning requirements this would be subject to marine licensing or consent requirements and therefore, no cumulative impacts are anticipated.
28.2 Increased Deviations Associated with Offshore Wind Farm Developments (including Transboundary)
466. As shipping and navigational receptors could route and therefore be cumulatively impacted by a number of offshore developments the principles of the cumulative assessments have been extended to 100nm. The routes passing through the East Anglia THREE site (and another development for cumulative impact) have been assessed with the results presented in Table 28.2.
467. It is noted that a zonal approach is also being considered within Netherlands territorial
waters, the outer edge of which is within 10nm, but as a number of the sites are dormant or unscreened they have not been considered cumulatively apart from Breeveertien II Offshore Wind Farm Development (Netherlands) which is 21.8nm miles away.
