Annex 1. The plan for the placement of said signal poles/ buoys

Description of planned activities

In order to carry out surveys at the planned wind farm, 8 signal buoys will need to be

positioned at sea.

The signal buoys will be constructed and anchored according to the attached diagram (Fig.

1). The coordinates of the buoy locations are shown in Table 1 (Tab. 1) and on Map 1 (Map.

1).

The signal buoys will be used to mark points along the lines of migratory bird observation

(so-called transect lines). Ornithologists conducting ornithological observations will record

bird flights that cross the line between the vessel anchorage and the line marked by the

signal buoys. The signal buoys will also be used to precisely measure the distance from the

ship of the passing birds.

Two scenarios for the handling of the signal buoys are possible:

I) Putting up the signal buoys each time before the single observation session of the

migratory bird surveys and taking the signal buoys after the single observation session.

II) Putting up signal buoys before the first observation session is performed and taking away

signal buoys after the last observation session is performed.

The planned dates for the surveys are shown in Table 2 (Table 2)

Anchoring system

The signal buoys will be anchored to the bottom using a metal block weighing

approximately 50-70kg. The signal buoy will be connected to the anchor using two sections

of rope and one section of steel chain. The steel chain will ensure that the section of rope

directly below the water surface is vertical. Signal buoys will be fitted with a radar reflector

and a red flag. The signal buoy will extend 2m above the water surface.

The total length of the signal buoy is 4m.

Taotlus poide paigaldamiseks

Seoses Liivi lahe tuulepargi uuringutega soovime paigaldada kavandatava tuulepargi alale

märgistuspoisid (ei ole navigatsioonipoid) linnustiku radariseire teostamiseks. Tööde alguseks

on 15. juuli 2023 ja lõpuks 30. juuni 2024.

Paigaldatavate poide asukohad on toodud Lisas (tabelis 1 ja kaardil 1). Kahes asukohas

paiknevad süsteemid koosnevad neljast poist (kokku kaheksa poid), mis ulatuvad 2 m üle

merepinna ja on varustatud LED tule ning reflektoriga. Täpsem märgistuspoi skeem on toodud

Lisas joonisel 1.

Poid soovime merre paigaldada alates 19. juulist 2023.

Palume väljastada luba kirjeldatud poide merre paigaldamiseks.

Lugupidamisega
