Phase II of China’s national emissions standards for marine engines are scheduled to come into force on 1 July 2021
Wärtsilä said it will introduce a packaged engine and selective catalytic reduction product aimed at complying with China’s Phase II marine engine emissions standard.
The new emissions regulations follow the introduction of Phase I of China’s emissions standard in 2018. Both phases apply to vessels on China’s inland and coastal waterways as well as fishing vessels, covering vessels operating in most rivers and around the country’s major harbour areas.
On 30 August 2016, China’s Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine jointly released the country’s first national emissions standards for marine engines used in domestic shipping in China. Phase I standards took effect in 2018, and the stricter Phase II standards will take effect on 1 July 2021.
The product package Wärtsilä has designed for compliance with the stricter Phase II regulations includes a Wärtsilä 20 engine fitted with a nitrous oxide reducer (NOR).
"The NOR is designed to effectively abate emissions of nitrogen oxides, while the incorporated dosing equipment ensures the precise amount of urea is applied to the system, and provides uniform mixing of the urea and ammonia with the exhaust gas," according to Wärtsilä Marine Power sales director Östen Lindell.
The company said certification and endurance testing for its Chinese-targeted product package is being carried out at Wärtsilä’s Shanghai-based joint-venture Wärtsilä Qiyao Diesel Company.
Emissions testing is carried out before and after the endurance test which is run continuously for nearly 2,000 hours, the company said, and a statement of compliance will be issued by the China Classification Society upon successful completion of the tests.
Wärtsilä said it expects to launch the product in Q3 2021.
