As part of our ongoing commitment to providing innovative and energy-efficient solutions for the maritime industry, we are excited to announce the addition of shaft generator systems to our portfolio.
Shaft generator systems are cutting-edge technologies designed to optimize a ship's energy usage by converting mechanical energy from the main engine into electrical energy. This eliminates the need for auxiliary generators during operation, leading to significant fuel savings and reduced emissions.
A shaft generator is integrated into a ship’s propulsion system and connected to the main shaft. Using the redundant power of the main engine, it drives the rotation of the generator rotor through the main shaft’s motion, generating electrical energy.
This process not only improves energy efficiency but also reduces fuel consumption since the fuel consumption rate of the main engine is typically lower than that of auxiliary generators.
Modes of Operation
Power Take-Off (PTO): Uses excess energy from the main engine to generate electricity, reducing reliance on auxiliary generators and improving EEDI (Energy Efficiency Design Index) scores.
Power Take-In (PTI): Provides propulsion power parallel to the main engine, enhancing vessel speed or supporting the main engine.
Power Take-Home (PTH): Acts as an emergency propulsion drive, enabling the vessel to reach the nearest shore in case of main engine failure.
Shore Power Connection: Adapts ship and shore frequencies to enable seamless power connections during docking, enhancing global compatibility.
EESG and PMSG Technology
Shaft generator systems utilize two advanced types of generators:
EESG (Electrically Excited Synchronous Generator): Generates a magnetic field through rotor windings powered by an external DC circuit.
PMSG (Permanent Magnet Synchronous Generator): Uses permanent magnets on the rotor, offering higher efficiency (up to 98%) with reduced maintenance requirements compared to EESG. PMSG systems are particularly notable for their lighter weight, smaller size, and absence of maintenance needs, making them ideal for modern vessels.
Key Benefits
Fuel Efficiency: Reduces reliance on auxiliary engines, improving fuel economy and lowering operational costs.
Environmental Impact: Decreases CO2 emissions, supporting sustainability and compliance with international regulations.
Versatility: Flexible operational modes ensure adaptability to various maritime scenarios.
Cost Recovery: Fast payback periods due to savings on fuel and maintenance.
This addition reflects our dedication to supporting the maritime industry's transition toward greener and more sustainable operations. With the potential to reduce fuel consumption by over 1,000 tons annually for certain vessel types, shaft generator systems represent a significant step forward in energy efficiency and environmental stewardship.
