Siemens has received a contract from Hyundai Heavy Industries to equip the United Arab Shipping’s (UASC) 17 container ships with its drive and power generation system, Siship SGM.

The project, aimed at catering to the power requirements of UASC ships, will be carried-out by the company’s Drive Technologies division.

As part of Siship SGM, Siemens will use a waste heat recovery system (WHRS) that generates super-heated steam from the hot exhaust gas and drives a two-stage steam turbine. The WHRS and steam turbine drive an electric generator to supply the on-board electric power system.

The exhaust gas from the propulsion main engine is used to generate clean power from the vessel’s exhaust gas, thus reducing fuel consumption and carbon emissions by up to 12%.

"Due to extraordinary reduction of fuel cost the total cost for container transportation will be reduced significantly."

In addition, the drive system reduces wear on the propulsion system and the auxiliary generators, and improves the reliability of the on-board power supply. It is also capable of operating as a motor or generator, the company said.

Siemens Drive Technologies division Strategy, Marine and Shipbuilding head Stefan Kraus said: "Together with UASC we worked as partner to adopt and comply with the very complex technical specifications from UASC.

"Due to extraordinary reduction of fuel cost the total cost for container transportation will be reduced significantly."

The A-14-class variant of UASC container ship is said to have a carrying capacity of 14,500 twenty-foot equivalent units (TEU), while the A-18-class ship has 18,800TEU capacity.
