Title: Emission control technologies for ocean going vessels (OGVs).

Principal Investigator / Author(s): Hamid Hefazi

Contractor: California State University, Long Beach

Contract Number: 06-327


Research Program Area: Emissions Monitoring & Control

Topic Areas: Mobile Sources & Fuels


Abstract:

Ocean going vessels (OGVs) contribute significantly to the economic activities and development of the state of California and the U.S. OGVs include general cargo ships, passenger ships, bulk carriers, oil tankers, vehicle/roll-on/roll-off (Ro-Ro) vessels, and containerships. The San Pedro Bay ports of Los Angeles (POLA) and Long Beach (POLB) are among the largest ports in the world. More than 40% of the U.S. containerized trade flows through these ports representing nearly $300 billion in annual trade. Economic forecasts project this trade to double by the year 2020 [Port of Los Angeles Inventory of Air Emissions (2005)].

A major adverse impact of this growth is the associated increase in local and regional air pollution. Emissions from marine diesel engines contribute significantly to the increase in particulate matter (PM), sulfur oxides (SOx), and nitrogen oxides (NOx). This report provides the ship owners, operators and other constituents a concise and informative document that can help them plan their mitigation strategies for meeting the CARB and other US emission standards. It reviews and to a certain extent evaluates many methods and technologies for reducing emissions from OGVs. The types of technologies reviewed include engine optimization, engine process modifications, exhaust aftertreatment, use of cleaner fuel, and combinations of these measures. This report also contains names and contact information for some of the providers of various technologies and additional references.
