After 30 years of experience in design and building gears which are ready for hybrid drive, we can summarize the following about the use of the REINTJES hybrid systems, combined with diesel-fueled engines: In most cases the level of the exhausted emissions is not significantly reduced, the prognosed fuel consumption saving often cannot be reached and therefore the over-all-efficiency is still at a comparable level to a conventional propulsion system. For those reasons REINTJES considered it to be necessary to substantiate the customer’s value in case of using a hybrid system for his application.
The consequently design as a “real hybrid”, means the combination of the RHS with gas-fueled engines, offers the following benefits:
• Significant reducing of CO2, NOx, SOx emissions and health relevant particulates
• Downsizing the main engine performance to avoid poor combustion
• The main engine sized for free sailing condition only, without sea/safety margin or bollard pull power
• The electric motor sized to power the sea/safety margin or pollard pull and the stopping maneuver The solution The RHS, comprising the gearbox, the electric motor and the frequency converter, is suitable for various applications and available with electrical machines from 60 up to 630 kWe.
In accordance with the customer’s individual requirements the REINTJES team of powertrain specialists provides the most suitable system solution for your application. All components of the system are optimally adjusted to each other and the functionalities in the gearbox design enable an easy connecting to the propeller.
The compact REINTJES Hybrid System (RHS) allows easy switching between the following different operation modes by means of its hydraulically operated clutches:
• Diesel mode: Diesel engine for propulsion only
• PTI mode: Electric motor for propulsion only
• PTO mode: Diesel engine for propulsion and shaft generation
• Boost mode: Electric motor and diesel engine in combination
• Dynamic Positioning mode: One diesel engine for propulsion only With conventional diesel driven propulsion systems low engine speeds would result in poor combustion in the main engines, higher fuel consumption and more emissions, and increase of wear and tear of the main engine.
With its Hybrid System REINTJES provides an exceptional solution in the field of emission-free drive technology which combines low noise and low vibrations. As with all other REINTJES products, the service for hybrid drives is available 24/7 all year round.
