Finnish marine engineering firm Wartsila has sold 33 engines to be installed across 11 newbuilds under construction in China.
The units, which are Wartsila 20 engines with dual-fuel capability, have been ordered by China Cosco Shipping and Cosco Shipping Bulk, the company said.
"The engine design allows for conversion to dual-fuel operation," the company said.
"The opportunity for conversion at a later stage is seen as an attractive option for owners and operators when preparing for upcoming emissions legislation, most notably the global 0.5% sulphur restrictions entering into force in 2020."
The upgraded Wärtsilä 20 engine came to market in December as a more powerful version of the Wartsila 20 diesel engine.
Wartsila's second quarter results saw a modest rise in profit on the back of an increase in orders for scrubbers.
