According to Modern Terminals, the contract is a demonstration of its commitment to the sustainable development of the industry and protection of the environment. It is also the first container terminal in the world to commence such a large-scale hybrid RTG conversion project. When the project is completed, by the second half of 2009, it is expected to reduce the fuel consumption of each converted RTG by nearly 40%.
The hybrid system will use DC/DC converters, which have been specially developed for RTGs by Yaskawa Electric Corporation, one of the largest manufacturers of motion and control products. It uses highly efficient super capacitors to store energy generated by the RTG’s main hoist motor during lowering motions. The energy is then reused during the hoisting cycle.
The use of new engine complying with US EPA Tier 3 Non-road Source Emissions Standards, coupled with the use of ultra-low-sulphur diesel (ULSD) by all container handling equipment at Modern Terminals, is expected to further improve emission standards.
