Germany's Schoeller Holdings has added four more feeder containerships to its orderbook at CSSC Guangzhou Huangpu Wenchong Shipbuilding in China.

Brokers said the company has declared options for two 2,700-teu vessels and two 1,930-teu ships. Schoeller confirmed the orders to TradeWinds.

The orders lift the two newbuilding contracts at the yard to a total of eight ships, owned by Schoeller subsidiary Cyprus Green World.
