Operations on the pipeline had been halted April 26 after it was damaged in attacks by tribes linked to al-Qaida, officials said.
The Yemen Post said Yemen LNG had to cancel six gas shipments because of the attacks.
French based Total E&P owns 39.62 percent of Yemen LNG. Its partners include Hunt, Yemen Gas Co., SK Innovation Co., Korea Gas Corp., Hyundai Corp. and the General Authority for Social Security & Pensions.
The project exports about 6.7 metric tons of gas a year, mainly to Asia.
Yemen's economy depends largely on its oil and gas revenues.
