Low-voltage motor saves on fuel costs

摘要

CSBC Corporation, Taiwan, has chosen to use Siemens' diesel-electric propulsion system in four semi-submersible deck cargo vessels (SSDCVs) to be built at its Kaohsiung shipyard. According to Siemens, the propulsion system offers better manoeuvrability when navigating at low speeds and is economical and energy-saving because of the low-voltage motors and frequency converters it uses, reducing fuel costs by 15% when compared with conventional mechanical propulsion technologies. This reduction is achieved with the help of power management features such as power plant protection, which ensures a higher availability of power through gen-set optimisation. The company also offers ballast pump systems that aim to control and dispose of pollutants, protecting the environment.
