Application of marine rudder propeller

Large tugboat, harbor tug, drilling platform vessel, ocean engineering vessel.

It is a kind of marine power propulsion which combined azimuth thruster and diesel engine. The whole set can be installed directly on the deck base. The set is hooded in the container. The vertical height is adjusted by mechanic equipments or hydraulic equipments. Therefore, ships can adapt the deeper to suit for the water depth and give full efficiency propulsive force.The ships can better satisify the full load and no load propellers immersion depth need. The combination design with contrarotating propellers can further shorten the diameter of propellers, save ballast water treatment cost and ballast water adjustment time.

Functional Characteristic of marine rudder propeller

· Rudder and thruster in one.

· Rudder propeller can steer in any direction of 360° above the water level

· Provide all-around thrust

· Increase the operation flexibility of the vessel

Istallation Type of marine rudder propeller

*Well installation

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

Our rudder propeller is mounted in the well.The stem length varieswith 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. 

Well installation varies with the distance between the Rudder Propeller and the diesel engine.When the engine room is very small, the Rudder Propeller can be near to the diesel engine and suitable for application in long-range transmission between diesel engine and rudder propeller. 

*Transom installation

Transom installation is one of the three installation types. It is used for ships and vessels whose space of engine room are smaller, such as floating cranes, mounting plate with sealing is fixed on the plate. That is, the upper of the Rudder propeller is fixed on the pinaxis, and the lower is clamped on the puching ring. When rleasing the thruster bearing, the propeller can easily be elevated backwards. 

Elastic suspension for special Sound Proofing is available for this mode of installation.

*Deck installation

The deck installation is a complete propulsion package. It is a reliable and compact propulsion plant. The chassis carries the totally enclosed propulsion system. The power of the diesel engine is transmitted to the rudder propeller through an elastic coupling, a hydaulic cluth and a universal shaft. The chassis daily fuel tank and so on. Installation is fast and simple because they are essentially self-con-rained. Only 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.
