Libya’s Zawiya oil terminal returned to normal operations on March 13 after workers who were blocking ships from docking agreed to end a one-day strike, two sources said.

Zawiya exports crude from Libya’s giant El Sharara oil field, which produces 300,000 barrels per day, more than a quarter of the North African country’s output.

Production at El Sharara had not been affected by the strike at Zawiya, an engineer at the field said. The field is operated by Libya’s National Oil Corp. in partnership with Repsol, Total (NYSE: TOT), OMV and Statoil (NYSE: STO).

“A deal has been reached between the strikers and the company and the loadings have resumed,” said a local oil source, asking not to be identified.

The Seagrace, which had been due to load on March 13, would berth at Zawiya soon, a local shipping source said. The tanker was chartered by Russia’s Rosneft, according to Reuters tracking data.

The strike at Zawiya began on March 12. The oil source said that only some workers were involved and that they had been pushing to get cash payments amid a liquidity crisis that has affected banks across Libya in recent years.

On March 13, a website that posts news from Azzawiya Oil Refining Co. said all loading operations had been stopped “by operators demanding an improvement of the situation in general”.

It was not clear how the dispute had been resolved, but oil sources had said on March 12 that there were negotiations with striking workers.
