Yemeni exports of liquefied natural gas (LNG) are running as normal despite one production plant, or train, undergoing planned maintenance, Total CEO Patrick Pouyanne said.

"In Yemen operations are running smoothly, gas is being produced, the power plant is still working," Pouyanne said on the sidelines of a conference in London.

"Presently one of the two trains is in planned maintenance shutdown, exports continue as normal."

The 6.7-million-tonne-per-year gas export terminal operated by France's Total lifted a two-week force majeure last month which had been announced amid deteriorating security following the collapse of the government.

A source at the Yemen LNG project said full exports would resume within a matter of days as the maintenance outages nears its end.

Two separate sources at Total said that while maintenance was indeed planned, its start was brought forward.

It was not immediately possible to confirm which of the facility's two production trains was shut.
