Copenhagen-based Evergas (formerly Eitzen Gas) has ordered another four ethylene carriers at China's Sinopacific Offshore & Engineering.
The ships will be built to either 12,000-cbm or 17,000-cbm class, and to the highest specifications, Evergas says.
Sources suggest the gas carriers will cost $43m each if the owner goes for 12,000-cbm vesels or in the low $50m-range if the 17,000-cbm size is chosen.
CEO Martin Ackermann said the company prior to the latest order had eight ships of this size under construction.
Evergas will during the coming months decide whether the additional four ships will be 12,000 cbm or 17,000 cbm, he added.
