Overview

Tri-Mer Marine Air Systems, and Clean Air Engineering offer a unique system for treating diesel exhaust from ships at dock.

Called METS-1, it is unequaled in providing emissions reduction to ports without the costly infrastructure of shore power.

In January 2014, the California Air Resources Board (CARB) began enforcement of the “Airborne Toxic Control Measure for Auxiliary Diesel Engines Operated on Ocean-Going Vessels At-Berth in a California Port” Regulation, commonly referred to as the At-Berth Regulation.

Covering all six ports in California, the at-berth regulation requires a 50% reduction in emissions from auxiliary diesel engines of ships at-berth. Through 2020, those reductions will be periodically increased to a maximum of 80%.

Initially, the only available technology approved to comply with the at-berth regulation was the shore power option, AMP. All California ports have installed significant shore power infrastructure; however, cases exist in which an equivalent emissions reduction option will be required. Those would include ships and or berths that are not AMP capable.

Tri-Mer Corporation, in partnership with Clean Air Engineering Maritime (CAE-M), has developed the Maritime Emissions Treatment System (METS), a CARB-certified alternative for compliance with the at-berth regulation.

The Tri-Mer/CAE-M emissions treatment unit is also the greenest solution: treatment byproducts are dry, non-RCRA and non-hazardous; there are no liquid wastes.
