Wärtsilä has received 33 Wärtsilä 20 engine orders for merchant auxiliary power applications in three major shipbuilding projects.

The engines will be installed in 11 new vessels being built in shipyards owned by China Shipbuilding Industry Corporation (CSIC), ordered by China COSCO Shipping and COSCO Shipping Bulk.

“These orders emphasise the value that the Wärtsilä 20 engine now adds to customer operations. Its high-power output, efficiency, and flexibility deliver true benefits that are of critical importance in lowering operating costs and meeting environmental legislation,” said Janne Klemola, product director, Wärtsilä Marine Solutions.


An attractive credential of the upgraded Wärtsilä 20 engine design it that allows for conversion to dual-fuel operation.

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 0.50% sulphur restrictions entering into force in 2020.

The new contracts cover three engines for four Very Large Crude Carriers (VLCC) being built at CSIC’s Dalian Shipbuilding Industry Corporation (DSIC) shipyard for China COSCO Shipping Energy; three engines for each of three Suezmax Oil Tankers being built at DSIC for China COSCO Shipping Energy and three engines for each of four Large Ore Carriers (VLOC) being built at CSIC’s Tianjin Xingang shipyard for COSCO Shipping Bulk.

Wärtsilä’s scope of supply includes complete auxiliary generating sets and all related engineering. Delivery of the equipment will begin in 2019.

The new Wärtsilä 20 engine family covers a power range from 700kW to 1980kW in 4L-9L cylinder configurations with nominal speeds of 900, 1000 and 1200rpm.
