APL ship

The new technology will be tested on an APL ship for the first year of the 3-year project. It is expected to result in air pollution reductions of some 80 to 85 percent in diesel particulate matter, 99.9 in sulfur oxide emissions, more than a 90 percent decrease in volatile organic compounds and another 10 percent reduction in nitrogen oxide pollutants.

A new technology that uses seawater to remove pollutants from the exhaust of ships’ auxiliary engines and boilers will be tested for the first time on a container vessel visiting Southern California in a three-year project starting this coming spring.

Co-sponsored by the Ports of Los Angeles and Long Beach, the $3.4 million project is expected to reduce the ship’s sulfur oxide emissions by up to 99.9 percent and particulate matter by as much as 85 percent.

“Many of the ocean carriers are looking for ways to reduce their vessels’ emissions and projects like this are an ideal way to demonstrate the effectiveness of new technology to the industry,” said Port of Long Beach Executive Director Richard Steinke.

Funded in part by a $1.65 million grant from the Technology Advancement Program, TAP, a joint initiative of the ports of Los Angeles and Long Beach, the seawater scrubber filtering technology will be tested on an APL container vessel.

The seawater scrubber features advanced emission control technology in which seawater is used to scrub, or filter, contaminants from a ship’s auxiliary engines and boiler before exiting the exhaust stack of a ship.

Once solid carbon contaminants have been removed, the seawater used during the scrubbing process is treated and cleansed before being discharged. The solid contaminants are contained and collected for later disposal.
