Backgrounds
Rising Global Concern for Environmental Issues
in Maritime Area

• International Maritime Organization (IMO)
• Introduced MARPOL Convensions Amendments
  concerning Atmospheric Pollusion
• Japanese Government
• Acceptance of Kyoto Protocol in 2002
• Set a Goal to Raise the Percentage of
  Transport by Rail and Coastal Shipping

3
Demand for Next-generation Coastal Ships

• More Environmentally Friendly

Gas turbines offer the potential to
significantly reduce the NOx Emissions.

NOx Emission Rate of Various Power Plants
(g/kW?h)
5
Status for Application of Gas Turbine to Marine
Propulsion System

• Limited to high-speed cruise ships and naval
  vessels where high power density is needed.
• Application of Aero-derivative gas turbine
  

Higher fuel consumption And higher component
prices than diesel engines
6
SMGTs Aim
Enlargement of Application of Gas Turbines for a
variety of ship class.
Development of a Low NOx and High Efficiency
2,500kW class Gas Turbine based on Industrial Gas
Turbine Technologies.

Objectives of R D in Phase 1

• Output Power of 2,500kW
• NOx Emissions below 1g/kWh
• Approximately one tenth of the
  high-speed diesel engine emission
• Thermal Efficiency of at least 38
• Equivalent to that of a high-speed
  diesel engine

Phase 1) (2) Power Output of 2300kW (200kW lower
than Phase 1) (3) Redesign of Power Turbine and
Recuperator
Reliability Demonstration (1) 1000 Hours Full
Load Operating Test (2) 1000 Cycles Endurance
Test
25
Total Energy Efficiency Improvement
Introduction of High Efficient Integrated
Co-generation system

• Efficient Use of Steam Produced by Exaust Energy
  Captured at Economizer
• Incorporation of Intake-air Cooling system
• constant output power and fuel consumption
  regardless of circumfirential condition.
• (2) Supply of On-board Service Steam

Summary
The SMGT (Phase 1) achieved all the
performance targets through the experimental
unit. At present, the endurance test for the
SMGT2 (Phase2) has just been carried out. In
2005, the SMGT will be installed on an
experimental vessel for demonstration tests in
Super Eco-Ship Project Success in these
tests would lead to realization of the
application of the SMGT for propulsion system of
actual ships in the wide range.
