Järeltegevuse lipp:	Järeltegevus
Olekulipp:	Lipuga märgitud

Dear Colleagues,

Please be informed of the following navigational warning, which will be published soon when cable repair work 
begins:
GULF OF FINLAND 
CABLE REPAIR OPERATIONS BY VESSEL DEEP CYGNUS CALL SIGN LACV8 
IN VICINITY OF POSITION 59-57.1N 026-05.8E. 
SAFETY DISTANCE 1NM.

Virtual AtoNs are not used in this case.
The above warning concerns repair operations on the EstLink 2 submarine power cable, carried out by Fingrid 
Oyj between 14 May and 15 July 2025 in the Finnish Exclusive Economic Zone (EEZ). The operation will include:
1.	Repairing the broken cable by connecting a ~1 km spare cable segment between two pre-identified 
intact cable ends.
2.	Laying the cable into a prepared corridor on the seabed, with possible additional trenching.
3.	Testing the connection and restoring it to service.
4.	Post-repair seabed survey using MBES and ROV.
The repair area is located within a rectangular zone defined by the following coordinates (ETRS89/WGS84):
*	59.951946° N, 026.079529° E
*	59.956746° N, 026.087269° E
*	59.951820° N, 026.111194° E
*	59.946087° N, 026.106621° E
Part of the repair zone extends into the Estonian EEZ. 
The main repair vessel is Deep Cygnus (IMO 9479541, call sign LACV8), supported by CTV Linda (MMSI 
230110310, call sign OG7951). 
During critical phases, Deep Cygnus will be unable to maneuver without halting the repair. A commercial guard 
vessel (tug) will be on-site 24/7 to ensure maritime safety and respond to unforeseen situations.
