In the Ecuadorian port city of Guayaquil, which handles about 65 percent of the total container traffic of the country, this German technology is in use as a Plug-In version in a container block 250 meters in length, supplying two RTGs with reliable power. “The port operator CONTECON Guayaquil SA first became aware of our E-RTG technology at last year’s TOC Americas in Buenos Aires,” explains Uwe Manthei, Senior Manager Global E-RTG Projects at Conductix-Wampfler. Management was particularly impressed by the potential for energy savings. Diesel-driven RTGs account for up to half of the power consumed in a port, and are thus responsible for a significant part of its CO2 emissions. Using Conductix-Wampfler’s E-RTG system, cranes can quickly be converted to cost-saving, environmentally friendly electrical operation. “We were convinced from the start that the test system would achieve the savings objectives we had hoped, so we are already planning another environmentally protective expansion of the port,” says the project lead from CONTECON.
