Councils in the highlands and islands are to press for measures to exclude dangerous cargos from the waters off the north west of Scotland.
The MV Jambo sank off the west coast
They are demanding navigation restrictions in the Minch and Pentland Firth, and consultation when incidents happen.
The number of large ships using the Minch has increased almost fourfold since 1999.
Highland Council and the Western Isles Council were alarmed at the delay in dealing with the MV Jambo, which sank at the mouth of Loch Broom, carrying a cargo of zinc compound and fuel oil.
The two authorities will press the government to remove the right of innocent passage from the Minch and the Pentland Firth.
The number of vessels over 300 tonnes going through Highlands and Islands coastal water has increased from 700 in 1999 to 2,500 last year.
The councils agreed to gather more information about the types of cargo carried by the ships.
They have also highlighted their opposition to derelict ships from the United States being taken through the Pentland Firth for scrapping in England.
Highland Council's vice-convener Michael Foxley described the handling of the Jambo as a fiasco which demonstrated the need for urgent action.
