Shipyards from South Korea and China are bidding to win the order, sources told LNG Prime on Tuesday.
Sonagnol is looking to order one firm and two optional vessels, they said.
No further details have been revealed.
Last year, some brokers reported that Sonnagnol is interested in booking up to three LNG carriers.
In April, HD Korea Shipbuilding & Offshore Engineering announced that it has won two suezmax tankers from Sonangol Shipping.
The 157,000-dwt tankers will be built by HD Hyundai Samho and are scheduled for delivery by May 2027.
Sonangol has a stake in Angola LNG.
Angola LNG is a joint venture of Chevron, Azule Energy, a joint venture of BP, Eni, Sonangol, and TotalEnergies.
In 2023, Angola LNG shipped its 400th cargo of LNG since the launch of the 5.2 mtpa Soyo plant in 2013.
A fleet of seven 160,000-cbm LNG vessels has been chartered on a long-term basis to transport Angola LNG cargoes to customers around the world.
