The worst case of oil spill that has taken place in Kalundborg Fjord
was on September 19, 1998, when the big oil supply vessel Buna
was to deliver oil to the oil tanker Nunki.
By accident that tanker tore a hole which was 1.5 by 30 cm
in the hull of the Buna.
Now the thick oil fuel oil started to pour out into the inlet.
The two environmental ships, the Gunnar Seidenfaden and the Marie Miljo
were sent for.
As soon as they arrived they began the clearing which took about 10 hours.
The fast clearing was a result of the fact that the fuel oil
does not lie on the surface of the water as a membrane;
it stays toegether in portions.
In total, 99000 litres oil gushed out in the inlet.
