A Bathymetric Survey that will cover all 102 Turbine positions, all of the Infield or Inter-Array Cables as well as the two Sub-Stations is scheduled for the WALNEY 1 & 2 OFFSHORE WIND FARMS.
The survey can be expected to start on or around Thursday 11th May and will be carried out by the Bibby Hydromap’s 15 meter survey catamaran ‘LIA’ as soon as this vessel completes and then demobilises from the ORMONDE EXPORT CABLE SURVEY.
‘LIA’ will operate on a 12 hr daylight only schedule and start date and length of survey is dependent on weather and conditions but the survey can be expected to run for approx. 7 to 9 days
All mariners should please note that as ‘LIA’ will be using highly sensitive Multi Beam Echo Sounding Equipment a wide berth, minimum 500 meters, is requested around the vessel at all times and passing vessels are requested to reduce speed if possible.
Attached for information is a small chartlet which shows the Wind Farm Layout with the Turbine positions as black dots, the Infield (or Inter-Array) Cables as red lines and the two Sub-Stations red triangles, there is also a picture of ‘LIA’
Also attached is the ‘Kingfisher Flyer’ which gives all of the relevant information concerning WALNEY 1 & 2 (WALNEY 1 is shaded blue – WALNEY 2 is shaded red).
Please note that the ‘Flyers’ are for provided for information purposes relating to the Wind Farm only and should not be used for navigation.
Please do not hesitate to contact me if you require any further information.
CARDINAL and SPECIAL MARKER BUOYS are marking the site, see chartlet attached, and as this area is still recognised as a construction site all mariners are requested and advised to mark the positions of these Buoys on their charts/plotters and unless there are matters relating to their own safety or the safety of others they should keep clear and not enter the buoyed area until the Wind Farm has been commissioned with the Buoys removed and you have been informed.
CTV’s and other service craft will continue to transit between the shore base at the Camell Laird Shipyard and the Wind Farm site ferrying out technicians engaged on monitoring work until final commissioning.
WAVE RIDER BUOYS
The North WAVE RIDER BUOY will remain on station to support the operational phase of the Wind Farm
Attached for information is a small chartlet which shows the Wind Farm Site and the Buoy positions

The unsettled weather has caused a delay but please be advised that the accommodation rig ’SEAFOX 2’ will shortly leave Holyhead under tow for the WALNEY EXTENSION (WOWO3+4) WIND FARM SITE.
‘SEAFOX 2’ will be accompanied by three tug boats, ‘ALP ACE’ will act as the lead tug assisted by ‘DMS STORK’ and ‘MULTRATUG 3’.
Once on site at the WALNEY EXTENSION (WOWO3+4) ‘SEAFOX 2’ will jack-up close to the WOWO3 Offshore Sub-Station (Z03), ‘SEA FOX 2’ will remain at this location for approx. 2 months.
All of the towing vessels will keep a listening watch on VHF Channels 16 & 12 and can be contacted for information relating to vessel movement only, mariners are requested to give a wide berth, minimum 500 meters, when passing.
The attachment shows pictures of ‘SEAFOX 2’, both afloat and under tow as well as jacked up on station, there are also pictures of the tug boats involved.
