Maersk Line, Ports of LA & Long Beach in 3-year project to measure air pollution benefits from $125M eco-upgrade; real-time tracking 24x7
Shipping company Maersk Line and the ports of Los Angeles and Long Beach are partnering to measure the environmental benefits of a $125-million upgrade for 12 Maersk container ships. This will involve the installation of high-tech equipment to track vessel emissions and energy efficiency over the next three years, enabling more transparency and ultimately reducing the environmental impact of vessels calling at the San Pedro Bay port complex. . . .
The two ports are contributing a combined $1 million to real-time tracking systems that represent an industry leading application to pinpoint vessel emissions while ships are at sea and at berth. . . .
The ports of Los Angeles and Long Beach will split the $1 million cost under their joint Technology Advancement Program (TAP). TAP is a grant program created under the ports’ landmark Clean Air Action Plan to accelerate the evaluation and demonstration of new and emerging clean technologies for reducing and ultimately eliminating harmful emissions from all port-related sources. Ships generate the lion’s share of air pollution associated with port activity.
Under its “radical retrofit” program, Maersk Line upgraded vessels that already plug into shore power at the San Pedro Bay ports. The additional improvements include redesigning the bulbous bow of each vessel, replacing existing propellers with more efficient models, and “derating” the main engines to make them more efficient at lower speeds.
The retrofit program also involved raising the bridge to increase each ship’s capacity from about 9,500 TEUs (twenty-foot equivalent units) to about 11,000 TEUs. This allows Maersk Line to carry more containers per vessel while decreasing their environmental impact per container moved.
The energy efficiency makeover is expected to decrease each ship’s fuel consumption by more than 10%, saving an estimated 10,000 metric tons of fuel on an annual basis. This would reduce greenhouse gas (GHG) emissions by an estimated 31,000 tons of carbon dioxide per year and lead to similar reductions of diesel particulate matter (DPM), nitrogen oxides (NOx) and sulfur oxides (SOx). A single ton of CO2 would fill a 1,400-square-foot house.
Since 2007, Maersk Line has reduced GHG emissions associated with its vessel operations by 42% on a per container, per kilometer basis. The Retrofits and TAP demonstration project with the San Pedro Bay ports will help Maersk Line reach its goal of a 60% reduction of CO2 and other pollutants by 2020. . . .
