Sinooutput propulsion system can be FPP and CPP for rudder propeller, azimuth propeller, bow thruster since 2007 year, as the market large demand from domestic and overseas with the ship types can be tug boats, fishing boats, ferry, construction ships and some high requirements personal ships and military ships. Now Sinooutput could do the certificate such as ISO, CCS, BV, RINA, DNV, KR etc. For the rudder propeller system field series products had been exported more than 30 countries, now the capacity can be 40-6000KW, and the installation can be paralleled type, deck combined installation type and stern type installation etc. With the design capacity as single propeller, twin propeller, with nozzle or without nozzle etc. The rudder propeller systems advanced features are high efficiency for the propulsion system, lower noise, better performance for operation, reducing the shaft resistance etc. Compare with other common propulsion system, Sinooutput ruder propellers mainly adopted by the end customers high requirements although it is not so competitive in short time, taking the idea of long using life it is more efficient. The rudder propeller system normally driven by electrical motor and marine diesel engines, if the ship owner has no idea, Sinooutput could help do the design jobs of the complete ships. Although it may be a long time job, and it must be worthy for each customer important project.
