Mekanord is a leading market supplier of marine reduction gearboxes and Controllable Pitch Propulsion (CPP) systems. The company designs & manufactures marine gearboxes and deliver either the gearbox only or the complete propulsion package including controllable pitch propeller and remote control system. Mekanord is a specialist on marine gearboxes and marine transmission solutions. its gearbox range covers a power range from 200 KW to 10000 KW and includes specialties such as:
Mekanord gearboxes are suitable for a wide range of marine propulsion systems where controllable pitch propellers are used. The controllable pitch propulsion system (CPP system) can be designed for either mechanical or hydraulic operation of the controllable pitch propeller. The pitch propeller is adjusted quickly and smoothly from full ahead to full astern by the use of state-of-the-art technology.

Controllable pitch marine propulsion systems offer a wide range of advantages. The most important are:
- Flexibility
- Efficiency
- Economy
- Manoeuvrability
A controllable pitch propulsion system ensures that the vessel will feature both maximum towing power and optimum speed. This is only possible using a controllable or variable pitch propulsion system. The CCP system technology ensures that it is always possible to achieve maximum engine efficiency regardless of the operation mode of the vessel. By adjusting the propeller pitch, the engine can operate at maximum power without overloading the system. At lower than maximum vessel speed, fuel consumption can be considerably reduced by lowering the engine RPM while increasing the propeller pitch to maintain the required vessel speed. In this way overall efficiency of the propulsion system is optimized.
-
