A final investment decision on the challenging Rovuma liquefied natural gas project in Mozambique will only be made after the partners have a better understanding on costs, according to a senior manager with Italian major Eni.

The huge two-train Rovuma LNG plant — to be sited at Afungi in Cabo Delgado province — will be fed by gas from the massive Mamba field in Offshore Area 4, where Eni and ExxonMobil are the key partners.
