Norwegian owner Klaveness Combination Carriers (KCC) has added four more optional vessels to its series of newbuildings in China.

The company raised NOK 350m ($40m) this week in a placement, plus a 5% over-allotment, and used the cash to declare options for the seventh and eighth ships in its Cleanbu series at Jiangsu New Yangzi Shipbuilding.

TradeWinds has reported these priced at $46.5m.
