U.S. oil major Chevron said on Friday that its Angolan subsidiary Cabinda Gulf Oil Company had declared force majeure at the Kuito offshore oil terminal on October 29, without giving a reason.

"The Kuito operation is currently undergoing a planned turnaround, and we do not anticipate any resulting production impacts from this action," a company spokesman said in an emailed statement.

Chevron is one of the west African country's top producers and typically loads two 920,000 barrel cargoes a month from its Kuito platform.
