Lessons learned during study of
USS Princeton
Retrofit opportunities aboard USS
Princeton (1/2)
• Improve motor, pump, and fan efficiency via whole-system
design.
• Use VSDs on variable loads.
• Improve duct and pipe pressure drops and entering/leaving
conditions.
• Improve power factor and understanding of its importance.
• Improve electrical power generation efficiency.
• Improve propulsion power efficiency.
• Improve pumping efficiency.
• Improve fan efficiency.
• Improve space cooling systems equipment and operations.
• Thermal integration, reusing “waste” heat for space heating,
refrigeration, flash evaporation for potable water, laundry,
cooking.
• Improve energy efficiency of potable water production.
• Improve lighting efficiency and quality.
• Improve air compressor efficiency.
• Upgrade systems sensors, monitoring and controls.

Technologies
Limited number—other speakers will elaborate
Propulsion: skysails
Skysails deploys kites up to 320m2 to reduce fuel consumption of cargo ships.
Propulsion: flettner rotor
E-Ship1, owned by wind turbine manufacturer Enercon, uses Flettner rotors.
The cylinders are rotated by a motor (not the wind!) and create a force
perpendicular to the direction of the wind (called the Magnus effect).
Hull: robotic shape
Protei is an oil-cleaning sailboat with a shape-shifting hull, leading
to a lower loss when the ship’s nose turns through the wind.

  • 8. Lessons learned during study of USS Princeton
  • 9. Retrofit opportunities aboard USS Princeton (1/2) • Improve motor, pump, and fan efficiency via whole-system design. • Use VSDs on variable loads. • Improve duct and pipe pressure drops and entering/leaving conditions. • Improve power factor and understanding of its importance. • Improve electrical power generation efficiency. • Improve propulsion power efficiency. • Improve pumping efficiency.
  • 10. • Improve fan efficiency. • Improve space cooling systems equipment and operations. • Thermal integration, reusing “waste” heat for space heating, refrigeration, flash evaporation for potable water, laundry, cooking. • Improve energy efficiency of potable water production. • Improve lighting efficiency and quality. • Improve air compressor efficiency. • Upgrade systems sensors, monitoring and controls. Retrofit opportunities aboard USS Princeton (2/2)
  • 12. Propulsion: skysails Skysails deploys kites up to 320m2 to reduce fuel consumption of cargo ships.
  • 13. Propulsion: flettner rotor E-Ship1, owned by wind turbine manufacturer Enercon, uses Flettner rotors. The cylinders are rotated by a motor (not the wind!) and create a force perpendicular to the direction of the wind (called the Magnus effect).
  • 14. Hull: robotic shape Protei is an oil-cleaning sailboat with a shape-shifting hull, leading to a lower loss when the ship’s nose turns through the wind.
