Cork County Council has convened its Oil Spill Assessment Team as part of its Oil Spill Contingency Plan in response to the sinking of a fishing vessel at Keelbeg Pier, Union Hall on Sunday night.
There was no crew on board at the time.
The Council's oil spill response contractor was mobilised and the area around the vessel was sealed off shortly after midnight on Sunday night to contain oil pollution risk.
Oils are being removed from within the containment area on a continuous basis, using absorbent booms and pads and the site continues to be monitored on a 24-hour basis.
Mariners in the vicinity of Keelbeg Pier are advised to navigate in the area with caution.
