CSSC Subsidiary Delivers China’s First Low-Speed LNG DF Marine Engine


According to an article published in Offshore Energy, CSSC’s subsidiary China Shipbuilding Power Group has delivered CX40DF, China’s first low-speed LNG dual-fuel marine engine, in Zhenjiang, Jiangsu.

Engine Delivery

The official delivery to China State Shipbuilding Corporation Limited (CSSC) Huangpu Station in Zhenjiang took place on 2 April 2021.

CX40DF Engine

CX40DF is reported to be China’s first independently-developed 5,000-kilowatt marine dual-fuel engine and the world’s smallest bore marine low-speed dual-fuel engine (Otto cycle) engine.

Dual-fuel Support

A dual-fuel engine can use both oil and LNG as fuel, switching between the modes. CX40DF utilises liquefied natural gas (LNG) as its main fuel. Compared with diesel engines, carbon emissions are reduced by more than 20 per cent.

Engine Design

The model, which took five years from design to delivery, is developed in accordance with international standards.

It is reportedly more economically efficient with higher thermal efficiency, which can effectively reduce fuel consumption.

CX40DF’s electronic control system, turbocharger, oil mist detector and other core components were independently produced for the first time, with 80 per cent of its parts made in China.

Independent Development Capabilities

The successful delivery of the model marks a step forward for China in building up its independent development capabilities in the marine power industrial chain.

Engine Applications

The first engine will be installed on a 9,500 cubic metres multi-purpose gas carrier built for Tianjin Southwest Shipping.

The model is reported to have a wide range of applications and is able to provide green power for 10,000 to 30,000 tonnes vessels.
