She was allowed into the Dampier The problem is that in almost all these cases the Archipelago and the cargo lightered with nil further coastal state response was so successful in preventing a spill, that the casualty received so little attentionthat we have insufficient data to enter it in the CDB.
Nonetheless the CDB does contain some instruc- tive examples of a coast state providing refuge.
Perhaps the most dramatic provision of refuge in theCDB involved the Pacific Colocotronis, loaded with 72,000 tons of volatile Algerian crude for Wilhemshaven, was off the Dutch coast on the 28th of September, 1975 when which grounded rounding Cape Point in April, 1968.

After the Kirki lost her forepeak tank 23 miles off the southwest coast of Australia, the Australian required the ship to be towed 700 miles north to an area north of the Dampier Archipelagothat could hardly be called a place of refuge. During the tow, the ship lost another 10,000 tons of cargo. On the other hand, theship was in horrible condition, 64,500 tons was successfully lightered, and the Australians could have towed the Kirki straightoffshore and sunk her.
