Major NOx reduction for semi-hybrid tanker Duandra

As Maritime Connector reports, the recently launched MTS Duandra is the world’s first semi-hybrid inland waterway tanker built by Shipyard Trico BV. This ship uses Volvo Penta diesel engines for both propulsion and generator set that helps to reduce emissions significantly. The two standard Volvo Penta D16 MG gensets on MTS Duandra generate power for on board electricity, thruster, cargo pumps and two electric engines which are part of the propulsion system. This setup reduces the total installed diesel power on board the Duandra to approximately 30% compared to a conventionally built ship. The savings made were used to invest in the extra electric equipment and also in catalytic converter and particulate filter on all the D16 engines on board. By using this technique the NOx emissions are reduced by approximately 70% to 90% and particulates are reduced by about 40%.
