Scrubber Barge to capture ship exhaust in Los Angeles and Long Beach

A new barge is being built to help capture and process exhaust from ships’ smokestacks in the ports of Los Angeles and Long Beach.

Produced and operated by Clean Air Engineering – Maritime, Inc. (CAE-M), based in San Pedro, Calif., the self-propelled barge will carry a system for capturing and treating exhaust gases from the ship’s stack called the System Marine Exhaust Gas Treatment System (METS-3), designed by Fassmer Technical Projects for
eliminate diesel emissions from auxiliary engines and boilers of ocean-going ships at berth or at anchor.

Nicholas Tonsich, President of CAE-M, said, “It is more important than ever to develop innovative technologies that help minimize emissions in ports. Clean Air Engineering – Maritime’s latest METS-3 will do just that.

The 26-meter-long, 13-meter-wide barge will be built at the U.S. Greenbrier Companies, Inc. shipyard in Portland, Ore.

The main propulsion system of the barge will consist of two electrically driven SCHOTTEL RudderPropellers type SRP 150 (400 kW each) with propeller diameters of 1.2 meters. The SRPs will work with biodegradable oils (EAL). SCHOTTEL said its delivery includes the complete electrical package, which includes electric motors, variable frequency drives as well as a portable control station for the SCHOTTEL MasterStick joystick system.
