Diesel-electric propulsion systems for biggest
shipyard in Taiwan reduce fuel costs
• Enhanced maneuverability when navigating at low speeds
• Economic, energy-saving vessel operation with Integrated Drive Systems
(IDS) comprising low-voltage motors and frequency converters
• Effective control and disposal of pollutants contribute to marine
environmental protection
CSBC Corporation Taiwan has chosen Siemens to supply diesel-electric propulsion
systems and other accessories for four 65,000-ton semi-submersible deck cargo
vessels (SSDCVs). The country’s largest shipyard is building the vessels for a
customer in Singapore. Compared to conventional mechanical propulsion
technologies, Siemens’ diesel-electric system will reduce fuel costs by up to 15
percent, resulting from unique power management features. Likewise, associated
propellers, rudders and thrusters will improve the vessel’s maneuverability when
operating at low speeds. Each propulsion system includes an IDS comprising low-
voltage propulsion motors and frequency converters that facilitate economic,
energy-saving vessel operation, as the components are perfectly matched to one
another. In order to protect the ocean from unnecessary pollution ballast pump
systems will help effectively control and dispose of pollutants, including seawater
microbes and settlings.
“Our state-of-the-art diesel-electric propulsion systems are designed to enhance the
fuel efficiency and maneuverability of marine vessels, while leveraging an
associated pumping technology to protect the surrounding environment,” says Mario
Azar, CEO of the Siemens Business Unit Oil & Gas and Marine. “We are pleased to
be working closely with CSBC Corporation Taiwan on this important project, and
with the overall adoption of our propulsion system in the oil & gas and marine
industries we serve.”

Siemens will supply the complete diesel-electric propulsion systems for all four
SSDCVs, to be delivered by the end of 2017. Each system, consisting of four 4,000
kilowatt (kW) low-voltage Simotics motors and four low-voltage Sinamics frequency
converters as well as their corresponding transformers, creates an IDS. Due to
optimum coordination of components, a cost-effective overall system has been
developed that is distinguished by reliable operation and high availability. The scope
of supply for each vessel also includes 6,980 kW main generators, medium-voltage
switchboards, power management systems, converters and transformers for ballast
pump as well as distribution transformers, a controllable pitch propeller, flap rudder
and a bow and stern tunnel thruster.
SSDCVs are designed for transportation of heavy loads, such as other vessels,
jack-up rigs, floating and non-floating modules. They can be submerged, enabling
cargo to be floated into place without moving it out of the water. Alternatively, they
can be loaded without activating the submerge feature. The need for this type of
vessel is expected to grow in the coming years.
