Combined cycled power plant

A new aproach to marine electric propulsion plant

Electric propulsion has established itself as an economic and reliable concept. Prime mover for the generators in such a plant has been the diesel engine. The combined cycle power plant designed by Siemens reaches one step further.

The prime movers for the generators are gas turbines with exhaust heat recovery units. These exhaust heat recovery units produce steam to run a steam turbine driving a generator.

This concept can have several advantages:

• Less space
• Less on-board maintenance
• Nearly no lube oil consumption
• Completely automatic operation in all operating modes
• Less noise and vibration
• Cleaner exhaust gases

These advantages can lead to several benefits:

Economical benefits

More space for cargo or passengers. It has been shown that a CCPP, compared to a similar diesel electric plant, can add 55 cabins.

Environmental benefits

Less pollution due to lighter fuel with less sulfur content and lower NOx emission. Shipping and water pollution come more and more in the focus of most governments and international environmental agencies. CCPP represents the propulsion standard to come.

Operating benefits

Fully automatic operation for all operating modes. And flexible plant for optimum performance with different operating profiles.
