CSBC Taiwan opts for Siemens systems for SSDCV newbuildsWritten by Nick Blenkey
AUGUST 18, 2015 — Taiwan’s largest shipbuilder, CSBC Corporation, has chosen Siemens to supply diesel-electric propulsion systems and other equipment for four 65,000 dwt semi-submersible deck cargo vessels (SSDCVs) ordered by a customer in Singapore.
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.
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 kW low-voltage Simotics motors and four low-voltage Sinamics frequency converters as well as their corresponding transformers, creates an IDS (integrated drive system).
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.
Siemens says that, compared to conventional mechanical propulsion technologies, the diesel-electric system will reduce fuel costs by up to 15 percent, while the associated propellers, rudders and thrusters will improve the vessel’s maneuverability when operating at low speeds.
“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.”
