400 SEAT ALUMINUM HIGH SPEED SHIP By Shanghai Qinghang Air-filmed Resistance-reduced Ship Co., Ltd., China

400 Seat Aluminum High Speed Ship

The energy-saving technology using a thin layer of air film used in the lower shape resistance shallow draught ship can achieve better effect of saving energy . The hallow draught ship is not conducive to reduce friction resistance because its wet area is bigger. But our technology can effectively form a thin layer of air film at ship bottom. It can reduce wet area about 50% for hallow draught high speed ship. The high speed ship and container ship designed and built by us can save energy by about 20%. The 200 seats aluminum high speed ship can reach speed 26kn when it uses two sets main engine, cummins KTA19-M700-522kW. The 480 seats catamaran ship can reach speed 29kn when it use 2 sets main engine cummins KTD50-M2-1343kW. Their transportation coefficient are about 5. The blower power used for reducing resistance is about 1% of the main engine and the cost of the reducing resistance system is about 0.3% of the cost of ship. 480 seats Aluminum Catamaran Passenger Vessel: Loa: 46m Lbp: 39m B: 10.8m Draught: 1.0m Waterjets: 2*MJP650 Passenger: 480p Main engine: ComminsKTD50-M2-1800rpm-1343kW*2sets Speed: 29kn
