The terminal took delivery of a first batch of 20 environment-friendly electrical RTGs in 2007. In line with its staged development, a second batch of 10 arrived at the stacking area in April 2008. All 30 of the RTGs in the new fleet were built by Shanghai Zhenhua Port Machinery Co. Ltd.
With a span of 23.5 m, the RTGs are capable of stacking one-plus-six wide and one-over-six high. They offer a number of advantages over traditional diesel RTGs, including lower energy consumption, quieter and cleaner operation and less need for preventive maintenance. A power regeneration unit is installed in each of the ZPMC units to reduce energy dissipation, and they are equipped with anti-collision and anti-lifting systems to ensure operational safety.
Andrew Milliken, chief executive officer of Da Chan Bay Terminal One, commented: “We make environmental consideration an integral part of the terminal’s culture and decision-making, and took the initiative to be the first container terminal in the world to use a full fleet of electrical RTGs. This initiative is proving to be successful and beneficial in terms of environmental friendliness, productivity and safety.”
