Greek owner George Economou has activated an initial deal reached last year to build four bulkers at China’s Nantong Xiangyu Shipbuilding & Offshore Engineering.

Brokers in Greece, China and the US reported earlier this month that Economou company TMS Dry will build the ultramaxes at the yard for delivery in 2024 for $32.5m each.

Managers at the Greek company did not respond to a request for comment but IHS Markit features the 63,500-dwt units — Hull No 113 to Hull No 116 — as ordered but not commenced.
