A trio of Matson vessels have just returned from Asia, where they have had wet scrubbers fitted.
US Jones Act carrier Matson has installed the wet scrubber exhaust gas cleaning across its D7-class vessels: Matson Anchorage, Matson Kodiak and Matson Tacoma.
The hybrid wet scrubber exhaust gas cleaning equipment uses a closed loop system when operating within 12 miles of the coastline. This pours fresh water treated with sodium hydroxide into the exhaust system and then collects and treats the wash water to counteract composites. This water is then disposed of at port.
Matson worked closely with the US Coast Guard and Environmental Protection Agency in certifying the effectiveness of the scrubbers.
These upgrades are part of a US$50 million investment in new equipment and upgrades to the company’s Alaska fleet.
