Germany's TB Marine has signed up for two 22,000-dwt chemical carriers with dual-fuel propulsion from China's Wuhu Xinlian Shipbuilding.

Additional ships are understood to be under discussion.

Yard officials confirmed the order for the tankers, which will have LNG and diesel propulsion, but said they were unable to disclose any details including price, options and delivery date.

Newbuilding brokers recently estimated the cost of a 19,900-dwt dual-fuel chemical carrier at about $34m, after a series order by Japan's Nisshin Shipping at China's Nantong Xiangyu Shipbuilding and Offshore Engineering.
