A pump accident at a Maersk oil rig has caused oil to leak into Danish waters in the North Sea.

Danish energy producer Dong said it is deploying float blocks in order to curb the spill, according to Danish news agency Ritzau.

Denmark’s Environmental Protection Agency (EPA) said the spill, which was caused by a malfunctioning pump at the drilling platform, is estimated to be roughly 820 barrels of oil and covers an area of around 6km².

EPA spokesperson Juliane Albjerg said the leak had stopped and that the spill is not expected to reach the coastline.
