Kawasaki Heavy Industries has obtained Approval in Principle for a liquefied natural gas (LNG) floating combined cycle power plant equipped with its own gas turbine and substation.
This approval was obtained from world-leading ship classification organization DNV GL*2 based on its latest “Gas Power Plant” rules, which were introduced in 2018.
The LNG floating power plant is an integrated system outfitted with LNG fuel tanks, regasification unit, gas turbine and steam turbine power generation equipment, control systems and switchyard.
The combined cycle equipment consists of two 34MW LNG fired Kawasaki L30A gas turbine gensets, two heat recovery steam generators (HRSGs) and a single steam turbine generator in a 2×1 configuration.
Kawasaki’s CCPP 80 combined cycle plant is rated at 80MW baseload output with an LHV heat rate of 6,622 kJ/kWh heat rate (54.4% combined cycle efficiency) and 11,000 cubic meter LNG tank capacity (2 weeks capacity).
Operationally it offers quick combined cycle start-up, wide operating range, relatively high ramp rate and good part-load efficiency. Plus dry low emissions combustion limit to achieve 15 ppm or less NOx.
Demand for floating power generation capacity is expected to be strong in Southeast Asia where island demand for electricity is growing rapidly, particularly islands and remote locations without stable power sources.
