Transom Installation Azimuth Thruster and Rudder Propellers

Transom Installation Azimuth Thruster can be freely steered in any direction of 360 degrees. It is a combined propulsion and steering unit, so that the all-around thrust is available and can be rotated to any horizontal angle.
Marine Azimuth Thruster can be operated by Electric , hydraulic or electric - hydraulic unit.
Quantity:
 

Transom installation azimuth thruster / rudder propeller is one of the three insallation types. It is used for ships and vessels whose space of engine room are smaller, such as floating cranes, passenger ships, inland and coasting vessels etc. A mounting plate with sealing is fixed on the plate. That is, the upper of the Rudder Propeller / Azimuth Thruster is fixed on the pin axis, and the loweris clamped on the pushing ring. When releasing the thrust bearing, the propeller can easily be elevated backwards.

Power transmission of the propulsion device depends on max input torque of the device. Propulsion application type, prime mover type and vessel type affect actual input torque. Please kindly contact our technical engineer for propulsion type selection.
Rated input torque MP of prime mover(diesel, electric motor or hydraulic motor) is important technical date for propulsion type selection. Calculation formula is as below:

Mp
≤ Sf * MR
Mp = N * 9549 / n
Sf = fz * fl * fs

Marks: 
Mp(Nm): Output torque of prime mover
Sf: Rudder propeller service factors
Mr(Nm): Max input torque of rudder propeller
N(KW): Output power of prime mever 
n(r/min): Input speed of rudder propeller

The desing torque can't be taken as the basis for propulsion type selection according to our experience.
Different operation conditions must be taken into consideration. Common safety coefficient Sf of torque design can be based on the following:
Sf=0.75: Full power continuous rating 24 hours service(Container ships, push tugs)
Sf=0.9: Intermettent service with eventual full load( harbor tugs, floating crane)
Sf=1.0: Auxilliray installations(Tunnel thruster, DP-installations)

Safety coefficient Sf of propulsion device should meet the classification navigation specification. Sf should be between 0.33-0.67 for those with ice class requirement. For those with special installation request please contact our technical engineer for type selection.
