6. Other notes Reduced clearances at the Kentish Flats and BritNed cable crossings. A Notice to Mariners was issued by the Hydrographic Office with reference to amendment of buoyage at Kentish Flats crossing and placing of an additional buoy at BritNed crossing. Kentish Flats Three special marks and a South Cardinal Mark have been installed to mark the four rock berms on the crossing of the Kentish Flats and London Array Export cable. At these crossings the typical sea bed level was -4m LAT. Due to the newly installed rock berm the depth in some areas is now -1.0m LAT. The navigational marks are installed in the following positions: 51 25.42N 001 05.68E 51 24.87N 001 05.77E South Cardinal exhibiting Q (6) + L Fl 15s light character 51 25.00N 001 06.36E 51 25.53N 001 06.28E BritNed cable crossing (51 28'.583N, 001 17'.417E). At this crossing the seabed level varies from -6.5m LAT to -9m LAT. Due to the newly installed rock berm the depth in some areas is now -4m LAT.

Additional Notes of Guidance to Fisherman Regarding On Going Construction Activities at London Array Offshore Wind Farm Construction works at London Array Offshore Wind Farm are complete and the wind farm is operational. However, remedial construction works are required at a number of turbines and inter array cable locations. This note should be read in conjunction with Code of Practice for fishing boats and fishing within the wind farm which describes more general guidance to fishing and access within the wind farm during the operational phase. Guidance to Construction Related Exclusions October 2013 November 2014 In order to avoid damage to the wind farm assets whilst remedial construction is conducted at London Array the following guidelines should be adhered to: Safety Exclusion Zones remain in operation for October 2013 and will be reinstated in March 2014 through to November 2014. This means an enforceable 50m exclusion from each turbine and 500m exclusion from a construction vessel will be in operation for this period. Between October 2013 and November 2014 an advisory 100m exclusion should be observed around each turbine and offshore substation due to the risk of exposures of array cable ends at foundations whilst remedial works are on-going. Cable reburial is required at the following locations and as such these areas should be avoided in totality: o Location 1 51 35.1492' N 001 27.9631' E length of exposure approx. 20 m o Location 2 51 35.4466' N 001 31.4780' E length of exposure approx. 8 m o Location 3 51 36.6527' N 001 26.5132' E length of exposure approx. 7 m o Location 4 51 38.1534' N 001 26.3310' E length of exposure approx. 5 m o Location 5 51 37.6977' N 001 28.6514' E length of exposure approx. 6m o Location 6 51 41.2319' N 001 29.8992' E length of exposure approx. 5 m o Location 7 start latitude 51 37.9540' N start longitude 001 26.0287' E end latitude 51 38.4120' N end longitude 001 25.9040' E length of exposure approx. 926 m o Location 8 start latitude 51 41.4290' N start longitude 001 30.8620' E end latitude 51 41.1147' N end longitude 001 30.3970' E length of exposure approx. 865 m Care should be taken within the wind farm site to avoid snagging array cables. Although not expected, natural seabed variation may reduce the depth of burial over buried cables without London Array s immediate knowledge.

Snagging cables not only poses a risk to health and safety but could also cause a serious risk of damage to wind farm assets.
