Global Energy Ventures (GEV) has again postponed its potential $1.2bn order for compressed natural gas (CNG) carriers.

The Australian company has a letter of intent (LOI) with Yantai CIMC Raffles Offshore to build four firm Optimum 200 ships, with four options.

The Sydney-listed outfit said on Tuesday it has extended the LOI for a further six months to 31 December.
