German shipping group Gesellschaft für Öltransporte (GEFO) has placed a order for six stainless-steel chemical tankers from China's AVIC Dingheng shipyard.
GEFO and AVIC signed a letter of intent for the construction of the six 3,600DWT ships in February.
The 99.9-metre by 14-metre newbuilds, which have an operating speed of 13 knots, are scheduled for delivery in 2020 and 2021.
Hamburg-based GEFO mainly operates on the Rhine River and between European coastal ports.
