Canadian shipowner Algoma Central Corporation has received the necessary approvals for its exhaust gas scrubbing systems on its Equinox-class vessels.
Developed by Wärtsilä, the scrubber units are capable of removing 97% of sulphur oxide emissions produced by vessel engines.
While the company installed the first scrubber unit on the Algoma Equinox vessel with the support of Wärtsilä last summer, testing of the system took place in early September this year.
Algoma director (Technical) Rob Houston said: "Testing confirmed the scrubber’s effectiveness at removing 97% of the sulphur oxide emissions from all engine exhaust streams onboard the Algoma Equinox.
"The approvals apply to each of the seven other Equinox-class ships, including two CWB-owned ships."
The company has also finished commissioning of the scrubber onboard Algoma Harvester, the second Equinox-class ship.
CWB Marquis, the third Equinox-class ship, is expected to arrive in Canada by the end of this year.
With high efficiency hulls, Equinox-class ships will able to achieve higher speed using less horsepower and also offer less fuel consumption and emissions.
This series includes four gearless bulk carriers, in which two of them are owned by the CWB and operated and managed by Algoma.
Algoma will complete the delivery of three Equinox-class gearless bulkers by this year end and the last one is expected to arrive in early 2015.
Meanwhile, first two Equinox-class self-unloaders are due to delivered in later 2015 and the remaining two in 2016.
