Port of Los Angeles posted this photo of one of NYK Line’s container ships undergoing a ship emissions capturing process carried out by Maritime Emissions Treatment System or METS.

The METS is barge-mounted and positioned alongside the vessel by tugboat. A tall crane mounted on the barge reaches to the exhaust stacks of the diesel auxiliary engines aboard the vessel. Exhaust is captured and funneled through flexible piping to a dry treatment pollution destruction system also mounted on the barge.

According to the developers, over 90% of the diesel pollutants are successfully treated, greatly alleviating air pollution from ships that do not have the capability to turn off their auxiliary engines and plug into shore-side Alternative Maritime Power (AMP) while at berth in the Port of Los Angeles.

Port of Los Angeles was first to start commercial application of a ship emissions capturing system of any sort back in April 2014. The project was funded in part by a USD 1.5 million grant provided through the Port of Los Angeles’ Technology Advancement Program.

Clean Air Engineering-Maritime (CAEM) and Tri-Mer Corporation developed the full-scale commercial model of METS.
