Finland's Wartsila is to supply engines for eight new 13,500-teu containerships ordered in China by CSCL.
The company said it will sell 32 of its 100MW-plus Auxpac 32 generating sets.
The order was placed with Wartsila's joint venture company CSSC Wartsila Engine (Shanghai) (CWEC).
China's Hudong-Zhonghua is building the vessels.
Delivery of the engines to the yard will start in the first half of 2017.
