Australia's Global Energy Ventures (GEV) is working on a second potential contract in Brazil that could see it deploy a large fleet of compressed natural gas carriers.

A request for information (RFI) has been received from an unnamed operator of multiple offshore oil and gas projects in the country, the Sydney-listed company said.

This is the second global oil and gas major that GEV has engaged with in Brazil to evaluate the export and commercialisation of gas using its new CNG Optimum vessel design.
