The exhaust gas cleaning systems are provided by Finnish firm Valmet, which has four production units and three service centers in China.

The scrubber system delivery for Cosco Shipping Lines will include a tailor-made open-loop scrubber system for main engine and generator engines including auxiliary systems and automation.

“Thanks to our solution, the scrubber systems can be installed to a single-island container vessel without losing any cargo capacity.  The systems are installed before the upcoming International Maritime Organisation sulphur cap and they will enable the use of higher sulphur oil, which is cheaper compared to using lower sulphur oil,” said Wang Shijie, senior sales manager at Valmet.

Valmet pointed out that the exhaust gas is washed with seawater in open-loop mode. All emissions are continuously monitored, and the complete exhaust gas scrubber system is controlled with Valmet's proven marine automation, Valmet DNA.
