Azimuth Thruster:

Azimuth thrusters are used when enhanced maneuverability is required in applications such as dynamic positioning, ship escort and ship docking services.Can be install as well tpe and deck type.Propeller as fixed or controllable.Azimuth thrusters there are two major variants, based on the location of the motor.

Mechanical transmission where a motor inside the ship is connected to the pod by gearing. The motor may be diesel or diesel-electric.

Mechanical azimuth thrusters can be fixed installed, retractable and underwater-mountable. They may have fixed pitch propellers (FPP) or controllable pitch propellers (CPP). Fixed installed thrusters are used for tugs, ferries and supply-boats. Retractable thrusters are used as auxiliary propulsion for dynamically positioned (DP) vessels and take-home propulsion for military vessels. Underwater-mountable thrusters are used as dynamic positioning propulsion for very large vessels such as semi-submersible drilling rigs.

Installation type of Rudder Thruster

The well installation is especially for tugs, ferries, well station, floating dock and survey ships.

The rudder propeller is mounted in the well. The stem length varies with the requirement of the application.

The top mounting plate of the well should ,if at all possible ,be above the waterline so that the rudder propeller

can be installed and removed when the ship is floating.

Deck installation

Deck installation is a complete propulsion package .It is a reliable and compact propulsion plant. The chassis

 carries the totally enclose propulsion system. The power of the diesel 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 system units. Installation is fast and simple

because they are essentially self con rained .Only to connect the minimum boses 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.
