CCS, BV, ABS, DNV Approved Electrical, Diesel Engine Driven Marine Rudder Propeller

The CCS, BV, ABS, DNV approved marine rudder propeller made by us has been approved by the China Classification Society and other international Classification Societies. And the products have been successfully installed, used and served on the ships. They are sailing in oceanic area of home and abroad. Rudder propeller is today used for all types and size of ships. We can provide with a series of specifications of Rudder propeller. The propeller can be freely steered through 360 degrees around the stem. Therefore the Rudder propeller is a combined propulsion and steering unit, so that the full thruster is available in any direction for the ship.If the prime engine is electric or hydraulic motor, the upper gearbox can be eliminated. 

The electric or hydraulic motor can be vertically mounted on the fixed flange and the power will be transmitted through a bevel gear in lower gearbox on to the propeller(L- drive).

The rudder propeller 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 ship, which are usually used in tugs, push boats, ferry boats and barges etc. Now the company is developing higher power RP to satisfy requirements from market. There are three installation types: Transom installation, Well installation, Deck installation.

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.

  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.

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 hydraulic clutch 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.
