and August 2013 surveys when an average of seven to eight unique fishing vessels were tracked per day, compared with the May 2013 survey when an average of two fishing vessels were recorded per day. During the January/February 2014 winter validation survey an average of five unique fishing vessels per day were recorded within 10nm of the East Anglia THREE site.
200. In terms of fishing vessel activity within the East Anglia THREE site, the greatest
level of activity was recorded during the August / September 2012 and July / August 2013 surveys with an average of four fishing vessels per day were logged within the East Anglia THREE site. During the May 2013 survey and January/February 2014 surveys a lower level of fishing was recorded within the East Anglia THREE site, with an average of two fishing vessels per day and two to three vessels per day respectively recorded. The greatest density of fishing vessel activity was recorded within the northern area of the site.
201.
It should be noted that a proportion of the unidentified vessels tracked on radar (non- AIS) are also likely to be fishing vessels.
16.3 Effects on Fishing Vessels (Safe Navigation)
202. Site design should take into consideration the ability of fishing vessels to navigate within the windfarm including a minimum spacing of 675 x 900 and alignment of turbines. However a final layout would require agreement with key navigational stakeholders such as the MCA and THLS. It is likely that smaller fishing vessels operating in the area would be able to navigate around including during construction and decommissioning (out with the current area of operation) activities as well as navigate safely within the array. There is potential that larger vessels may be displaced from the site especially during construction. It is noted that fishing vessels are primarily local to the area and would be familiar with the current phase of operation and likely areas of activity especially during the construction and decommissioning phases.
203. Effects on fishing vessels are considered in full in Chapter 15 Shipping and Navigation, Section 15.7.3.
