U.S. yard Greenbrier Marine has an order to build a self-propelled scrubber barge to capture and treat exhaust emissions from ships in the ports of Long Beach and Los Angeles. The 26m-long and 13m-wide barge will be operated by U.S. company Clean Air Engineering - Maritime, Inc. (CAE-M), based in San Pedro in California.
The system to capture exhaust from ships is called the Marine Exhaust Treatment System or METS-3 and was designed by Fassmer Technical Projects to remove diesel emissions from the auxiliary engines and boilers of ocean-going vessels while at berth or anchor. Additional METS systems will be produced and operated in several other California seaports. The main propulsion system of the scrubber barge consists of two electrically driven Schottel rudder propellers (SRPs) of type SRP 150 of 400 kW each featuring propeller diameters of 1.2m. The SRPs will run on biodegradable oils (EALs).
