At the beginning of July, Wison’s subsidiary, Wison Heavy Industry, also started the fabrication of topsides for Eni’s Congo-bound floating LNG (FLNG) unit.

The Chinese shipyard is constructing the 2.4 million tonnes per annum (mtpa) FLNG unit to be deployed offshore the Republic of Congo to increase production and export.

The 380-metre-long and 60-metre-wide FLNG unit will be anchored at a water depth of around 40 metres in the Nene Marine Field area, around 50 kilometres offshore Pointe Noire. It will be able to store over 180,000 cubic metres of LNG and 45,000 cubic metres of LPG.
