Shanghai Qinghang Ship Company is established by Cai
Jinqi, who invented the technology of forming a thin layer of air film
at ship bottom to reduce resistance. He spent his life in research on
energy saving technology for ships and has gained a lot of experience.
The company’s employees are mostly professionals graduated from
Shanghai Jiaotong University. Our company engages in designing ships
using our technology, providing technology and consulting on
air-filmed high speed ships and container ships to other company,
promoting this high value adding resistance reducing technology. Our
company cooperates with other companies to design and build high-speed
ship and container ships using our technology to form a thin layer of
air film at ship bottom to reduce resistance. Our technology is one of
Shanghai government’s high-tech transforming projects. It can help
ships to save about 20% energy. It is the leading technology in the
world that first solves the problem of forming a thin layer of air
film at ship bottom. |

Providing
saving power air-film high speed ship and container ship technology
at low quote |
|
|
Air pumped into ship bottom can form air film when
passing through the equipment installed. Our technology can reduce
resistance and promote speed because the air film substitute ship
bottom to contact with water. |

Providing
power saving air-film high speed ship technology |
|
|
Using our optimized ship shape and technology to reduce
resistance, tests show that high-speed ship can save about 30% power
when compared to hovercrafts. Our power saving air-film high-speed
ship is cheap to build, more energy efficient and easy to maintain. |

Providing power saving
air-film container ship technology |
|
|
To use our technology on container ship, we need to
install pumps on ship and devices at ship bottom in order to form a
layer of air film at ship bottom. Our technology can reduce contact
area of water and ship by 35%, which can reduce resistance and save
a large amount of energy. A 4200 TEU container ship can save about 6
million USD per year. |

Save about 20% energy using our technology. |
|
|
The power of fan used is about 1% of total power. |
|

The design Froude number Fr may be bigger than 0.25 |
|
|
When
the fan is not working, the equipment installed on ship bottom will
add about 1.5% of ship resistance.
|
|
|
The cost of our equipment is lower than 1% of the total
cost of the ship. It is equal to the price of energy saved in
several months. |
