On the 24 June 1973, the Liberian oil tanker the Conoco Britannia grounded in Humber estuary due to engine failure. This accident caused 500 tonnes of crude oil to be spilled.

During the response operation, dispersants were spread on the surface of the sea and on the beaches affected. The cargo remaining in the damaged tank was pumped out.

The impact on the coastline was minimal, however a number of oiled birds were found.
