Maritime Hybrid Drive (MARHY®)
The MARHY® system represents a state-of-the-art redundant propulsion solution tailored for ships powered by slow-speed (two-stroke) diesel engines. Designed to prioritize economic and environmental efficiency, MARHY® delivers exceptional performance in slow steaming and precise maneuvering. With integrated Power-Take-Home (PTH), Power-Take-Off (PTO), and Power-Take-In (PTI/Booster) functionalities, it ensures versatile power management for modern vessels.
Key Features and Benefits
Enhanced Efficiency
MARHY® allows for PTO from the main engine thus reducing fuel consumption, providing cost-effective and sustainable propulsion without compromising performance.
Adaptable Power Output
The system can be used in combination with both Fixed Pitch Propellers (FPP) or Controllable Pitch Propellers (CPP), allowing PTO/PTI/PTH powers up to several MW. This adaptability ensures its suitability for a wide range of ship types.
Flexible Integration
With PTO, PTH, and PTI functionalities, MARHY® offers flexible power solutions tailored to meet specific project needs. Whether generating auxiliary power, supporting hybrid propulsion, or providing a booster mode, the system enhances operational versatility.
