Newly designed frequency converters enable system installations and emissions reduction in port cities outside the US.
(SEATTLE) March 12, 2012 – While the projected worldwide growth of the cruise industry in 2012 and beyond will be an economic boon for port cities, it also means greater environmental impact with idling diesel engines polluting the air. Cochran Marine, the leading provider of marine shore power systems in North America, announces an expansion of its solution to address these environmental concerns on a global scale. The company has converted the frequency of its existing 60 Hertz (Hz) system to support the global 50 Hz market in order to bring shore power to ports in Europe and around the world.
Until now, there was no way to convert utility power in 50 Hz markets — including Europe and Asia — to work with cruise ships, which run on 60 Hz power. The Cochran Marine Shore Power System converts the standard voltage of any cruise terminal worldwide to match that of the vessel. Through a closed transition process, it seamlessly transfers electrical power to the ship while it is docked. By connecting to shore power, cruise ship operators can turn off diesel engines and run entirely on electrical power while in port, which reduces carbon emissions by approximately 87 tons per call.
“By converting the available 50 Hz power source to the standard operating power of 60 Hz, we can now bring our tried and true ship-to-shore solution to established and emerging markets around the globe,” says Michael Watts, VP of Marine Development. “This expansion of our Shore Power System represents our commitment to continuing innovation with proven technology which reduces toxins that impact air quality.”
The technology is fully automated, synchronizing the delivery of electricity between the system installed at the terminal and an equipped ship — without power disruption. This automation provides real-time data in order to calculate the reduction in emissions per call, as well as remote monitoring of the system.
The Cochran Marine Shore Power System is a standard design of electrical components that can be customized according to site conditions, including configuration of the cable positioning device for tide conditions or docking arrangements.
The Cochran Marine Shore Power System has been in service in the North American 60 Hz market for nearly a decade. It is currently in operation at North American ports including Seattle, San Francisco, San Diego, Long Beach, CA and Vancouver BC.
“Cochran Marine provided a customized shore power solution at Canada Place that is compact, flexible and effective,” says Carmen Ortega, Port Metro Vancouver’s manager of cruise trade development. “Port Metro Vancouver is pleased to work with industry leaders like Cochran to bring innovative sustainability programs to our port. Since launching in late 2009, the successful shore power initiative has seen 90 vessel calls connect — which translates to a reduction of over 3,000 tons of net greenhouse gas emissions.”
The Halifax Port Authority is initiating the construction of a shore power system in conjunction with Cochran Marine. Located in Nova Scotia, the Port is anticipating an influx of cruise ships. Beginning in September 2014, the port will enable their shore power system at the Port’s Pier 20, 21, and 22. The system will support up to a 20MW ship hotel load.
