Deck installation Azimuth Thruster / Rudder Propeller

The propeller can be freely steered through 360 degrees around the stern. It is a combined propulsion and steering unit, so that the full thrust is available in any direction for the vessel.
The Rudder Propeller / Azimuth Thruster can be operated by mechanical, hydraulic or electric - hydraulic unit, and can be in active service as main propulsion, auxiliary propulsion and dynamic positioning of the vessel, which are usually used in tugs, push boats, ferry boats and barges etc.

Deck

Deck installation azimuth thruster / rudder propeller is a complete propulsion package. It is a reliable and compact propulsion plant. The chassis carrries the totally enclosed propulsion system. The power of the dieseln engine is transmitted to the rudder propeller through an elastic coupling, a hydraulic clutch and a universal shaft. The chassis is constructed with a hydraulic system, an electric control box, daily fuel tank and so on. Installation is fast and simple because they are essentially self-con-rained. Only to connect the minimum hoses and cables can make it available to obtain thrust. The deck installation unit merely has to be mounted and bolted onto a foundation of deck. Rudder propeller is mounted at the rear chassis.
The rudder propeller can be mechanically or hydraulically raised or lowered in vertical direction by means of a depth adjustment facility. This serves to ensure maximum propeller thrust at all vessel draughts by maintaining the correct propeller immersion.
For maintenance purposes, the rudder propeller can be pivoted out of the water to the rear hydraulically or mechanically by hand.

Arrangment
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.
