The local subsidiary of Royal Dutch Shell Plc in Nigeria declared force majeure on Bonny Light crude oil exports effective 12:00 local time on Thursday, Reuters reports.

The Shell Petroleum Development Company of Nigeria Ltd said the declaration followed the shutdown by operator Aiteo of the Nembe Creek Trunk Line, one of two pipelines that export the grade.

Bonny Light was under force majeure in June due to the outage of the other export line, the Trans Niger Pipeline, delaying export cargoes by roughly 10 days.
