Reuters had reported on Friday that loadings of LNG cargoes have been delayed from the plant, located in the eastern Malaysian state of Sarawak.
Petronas said the production issues at Bintulu are under control and have been resolved, adding that they are "part and parcel of operations".
"While the planned maintenance activities take place, Petronas continues to deliver upon its supply commitments to customers, leveraging on the multiple LNG production modules at (Bintulu) and through close collaboration with our feed gas suppliers," it said in an emailed statement to Reuters.
Petronas is the world's fourth-biggest LNG exporter. The Bintulu plant, with a production capacity of about 30 million tonnes per annum, supplies to customers in Japan and China, among others.
