German shipowner Briese Schiffahrt has lifted its containership newbuilding programme in China by up to 10 ships worth more than $300m.

The Leer-based company has exercised options for two more 1,800-teu feeder vessels at Huanghai Shipbuilding, based in Shandong, in a deal worth around $52m.

The order comes on top of contracts placed earlier this year for eight similar vessels at two Chinese yards.
