Anglo-Dutch supermajor Shell has launched a pre-qualification process in Nigeria covering a long-awaited oil spill clean-up operation in the Niger Delta's Bodo Creek.

The move came three years after Shell accepted liability for two major oil spills in the area in 2008 and agreed to pay £55 million ($83 million at 2015 exchange rate) to the Bodo community and to clean up their land and creeks.
