Wärtsilä will supply a broad scope of solutions for the new LNG-fuelled container ships ordered by CMA CGM. This latest series comprises twelve12 container vessels to be built in China. Six 13,000 TEU container vessels are being built at the Hudong-Zhonghua Shipbuilding, with the other six 15,000 TEU container vessels under construction at the Jiangnan Shipyard.
The Wärtsilä equipment is scheduled for delivery to the yards commencing in 2022, and the first of the twelve vessels is expected to be launched in Q3 2023. The company supplied a similar scope for nine 23,000 TEU CMA CGM vessels, which have already been delivered and five 15,000 TEU whereof two vessels are delivered, and three vessels are under construction now.
Dual-fuel engines and real-time data
By contracting these ships to operate with LNG fuel rather than conventional marine diesel fuels, CMA CGM seeks to decarbonise its operations. LNG eliminates almost all air pollutants such as sulphur oxides (Sox: -99 per cent) and nitrogen oxide (NOx: -92 per cent) and particulates (PM10: -91 per cent) and achieves a first step toward decarbonisation. The dual-fuel gas engines on the vessels are already compatible with renewable energies such as biomethane, synthetic methane and e-methane.
The selected solutions are all designed to deliver high efficiency and environmental sustainability. They include for each vessel five Wärtsilä 34DF dual-fuel auxiliary engines, sixty engines in total, delivered from the joint venture in China, Wärtsilä’s Nacos Platinum integrated control system, propulsion control system, STC-13 series Sewage Treatment Plants and Fuel Gas Supply System fitted with the company’s Operational Performance Improvement and Monitoring (Operim) system. This utilises the latest digital technology to provide data in real-time to allow the system to operate at optimal efficiency at all times, and in all weather and sea conditions.
