German propulsion specialist SCHOTTEL said it will showcase propulsion solutions with the focus on offshore-applications and hybrid concepts at Nor-Shipping 2015.
 
The SRP 3000 PTI is a hybrid propulsion system consisting of a mechanical Rudderpropeller (1,900 kW) and a PTI mounted on the above-water gearbox opposite the power input. The PTI is an electric motor which provides 460 kW for maneuvering and transit when the diesel engine is switched off. The diesel engine can be used for operation with higher load requirements, and the electric motor can supply supplementary power as needed. This option is available in boost mode, at maximum bollard pull or for high torque requirements at part load.  The system allows for simple switching between diesel and electric operation while on the move, and achieves smooth transitions. The PTI and diesel engine are controlled centrally as a single system.
 
The new underwater mountable system, the SRP 9000 LSU, with a power range of 4,800-5,500 kW is designed for the harsh conditions offshore and helps reduce docking times thanks to cost efficient mounting and dismantling on the open sea. It is compact and equipped with a hydrodynamically optimized housing. For the different thruster requirements on ships or semi-submersibles, propeller shafts are available as both tilted and standard variants. 
 
The new SRP 4000 USV retractable system (2,000-3,000 kW) is characterized by a highly compact design, thus enabling low installation heights and avoiding the need to encroach upon the decks above. With the drive motor located beneath and to the side of the helical gearbox as well as the completely redesigned Spindle Drive, this Rudderpropeller variant stands out considerably from the retractable systems available on the market and has a relatively small footprint as well.
