Cork County Council has confirmed that sealed barrels on board the MV Alta which ran aground near Ballycotton will be removed by helicopter.
The council's Oil Spill Assessment Team met again yesterday and said its marine contractor has begun making preparations for the safe removal of the sealed containers of diesel and hydraulic oil.
The operation is weather dependent and is unlikely to take place before next week.
An individual claiming to represent the owner of the MV Alta made contact with the Revenue Commissioners earlier this week.
A Revenue spokesperson said the Receiver of Wreck will be pursuing the matter further.
The MV Alta is currently on rocks near Ballycotton after running aground during Storm Dennis last Sunday.
The 80-metre vessel ship was abandoned by its crew more than a year ago in the Atlantic Ocean.
Anyone who lays claim to the vessel has one year to establish their claim.
