* "Minor fire incident on turbine compressor" on July 11

* Total says evaluating impact on production

* Traders say about 30,000 bpd of oil output affected

(Recasts with Total confirmation, detail)

LONDON, July 16 (Reuters) - Total SA (TOTF.PA: Quote) has declared force majeure on cargoes of Nigerian Amenam crude oil loading from the middle of July, the French oil major said on Thursday.

A Total spokeswoman said the force majeure was a result of technical problems and not militant activity that has affected tens of thousands of barrels of Nigerian crude from the Niger Delta this year.

"We can confirm that following a minor fire incident on a turbine compressor on July 11, we declared force majeure on July 13," the spokeswoman said.

"Limited production has restarted and the effective impact on production is currently being evaluated."
