Hitachi Zosen has received an order for two high-pressure selective catalytic reduction (SCR) units to be used with two-stroke engines on chemical/oil tankers under construction in China.

The NOx abatement systems are destined for two 7,999dwt chemical tankers to be built for a European customer by AVIC Dingheng Shipbuilding, and will enable compliance with Tier III NOx limits in place in North American and Caribbean Emission Control Areas since last year, as well as those due to come into force in the Baltic Sea and North Sea from 2021.

Jitsuhiro Yamaguchi, director, marine machinery & SCR systems, Hitachi Zosen, said: “Hitachi Zosen is the only commercial distributor [of SCRs] officially approved by MAN Diesel & Turbo. We aim to make our system the de facto standard for compliance with Tier III environmental regulations.”

Hitachi Zosen claims to be the only manufacturer producing both two-stroke engines and SCR units. It will deliver the high-pressure units – to be placed upstream of the turbocharger - to Dalian Marine Diesel, which was contracted to manufacture the marine diesel engines by AVIC.

Although the ship owner was not disclosed, the specifications match an order placed with AVIC Dingheng by Swedish operator Sirius Shipping. In September the company ordered two 7,999dwt chemical product tankers, specifying high-pressure SCR units and a MAN B&W 6S35ME-B9.5 prime mover. A matching engine order was confirmed by Dalian Marine Diesel last month.

The delivery of the SCR units is scheduled for October and November. The Sirius vessels are due to be delivered next year.
