YOUR PROPULSION EXPERTS SCP · SCHOTTEL CP PROPELLER Controllable-Pitch Propellers for all ships up to 30,000 kW.

RELIABLE PROPULSION SYSTEMS RATED AT UP TO 30,000 KW SCHOTTEL Controllable Pitch Propellers (SCP) are the appropriate solution when highest propulsive efficiency for changing speed or load are required and best manoeuvrability is needed. No matter whether big ferries, container ships, heavy lift vessels or offshore supply vessels are to be equipped. OPERATION PRINCIPLE The power spectrum ranges from 1000 kW to 30,000 kW, with propeller sizes varying between approximately 1.5 to 8.0 metres. Advanced calculation methods allow the SCP to be optimally adjusted to the hydrodynamic conditions on...

SCP · SCHOTTEL CP propeller propeller shaft hydraulic piston propeller blade The SCP power range starts at approx. 1000 kW and goes up to 30,000 kW, with corresponding hub diameters from 0.46 m to 2 m. The propellers are available with 4 or 5 blades, the standard version being the four-bladed design. SCHOTTEL supplies the complete package including the CP propeller, shaftline, hydraulic system and remote control system, if required including stern tube with seals, nozzle and gearbox.

USER-FRIENDLY AND RELIABLE REMOTE CONTROL SYSTEM REMOTE CONTROL FOR THE SCP The remote control system is designed to provide automatic control of a SCHOTTEL Controllable Pitch Propeller. It is based on a microprocessor-controlled system architecture with 2-wire bus communication between central unit, ECR and bridge. An HMI (human-machine interface) allows clear, userfriendly control, set-up and maintenance. The system is type-tested to GL, LRS and ABS (other classes on request) and meets class requirements according to AUT24 and UMS. It is powered with 24 V DC. A separate supply should be...

MEETING YOUR DEMANDS WITH THE RIGHT PROPELLER DESIGN DESIGN DEPENDS ON EXPERTISE Designing a CP propeller blade is a complex process, requiring an extensive range of expert knowledge in the specialized fields of fluid physics and mechanical engineering. In addition to hydrodynamic blade design, the calculation of hydrodynamic loads and their effects when the blade pitch is changed in various operating conditions are of great importance. In order to provide advanced blade shapes and to satisfy ever growing requirements, latest calculation methods are applied, refined continuously by means of...

QUALITY – COMMITTED TO DURABILITY AND RELIABILITY QUALITY MEANS MEETING EXPECTATIONS Delivering quality is not just a question of good will. We develop and build propulsion systems which have to prove themselves under the toughest conditions in worldwide service. We are responsible for ensuring that these systems can be optimally commissioned, operated and maintained – a fact which our employees are acutely aware of. We see our work as an elementary link in our customers’ value creation chain.
