The Coast Guard says 11 people have abandoned a fishing vessel that was stranded off the coast of Cork.
The UK-registered Piedras was reported to be in difficulty around 60 miles south-west of Mizen Head shortly after 9.00am on Wednesday.
The vessel was reported to be taking on water and had lost propulsion.
It is now on fire, the Coast Guard says.
The Shannon-based Coast Guard helicopter, R115, was sent to the scene scene - as was an Air Corps plane.
A second Coast Guard helicopter, the R116, was placed on standby at Cork Airport.
The Naval ship the LÉ Samuel Beckett is also heading for the area.
The Coast Guard says the crew abandoned the ship and are safely onboard another fishing vessel which was sent to assist, the FV Armaven.
No injuries were reported.
