Maersk Line, Ports of Long Beach and Los Angeles Partner to Measure, Reduce Air Pollution from Ships
Shipping company Maersk Line and the ports of Long Beach and Los Angeles are partnering to measure the environmental benefits of a $125 million upgrade for 12 Maersk container ships. It 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 three-year data collection and analysis project, called "The Connected Vessel Programme," builds on the $125 million Maersk Line has invested in its "radical retrofit" program to reduce fuel consumption and increase the capacity of the vessels that regularly call at the San Pedro Bay ports.
The project will continuously record how much fuel each engine uses in conjunction with speed, engine power, weather and other operational variables through use of mass flow meters and an interface to the on-board Integrated Control System to capture performance data. Information will be uploaded to Maersk Line servers via satellite. Each ship will be able to communicate in real-time with Maersk Line’s Global Vessel Performance Centre to increase operational efficiency.
The retrofit program also involved raising the bridge of the ships to increase each vessel’s capacity from about 9,500 TEUs 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 percent, 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 (CO2) per year and lead to similar reductions of diesel particulate matter (DPM), nitrogen oxides (NOx) and sulfur oxides (SOx).

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’ 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 much of the 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 of the ships to increase each vessel’s capacity from about 9,500 TEUs to about 11,000 TEUs. This allows Maersk Line to carry more containers per vessel while decreasing their environmental impact per container moved.
