​Electric and Hybrid Vessels

​
Advancing Lower-Emission and More Efficient Maritime Propulsion
​
KOSCO SD provides comprehensive engineering and technical services for the design, evaluation, integration, and implementation of electric and hybrid propulsion systems.
We support shipowners, designers, and shipyards in developing lower-emission and more energy-efficient vessels through newbuild, retrofit, and Battery Ready projects.

When properly designed for the vessel’s operating profile, electric and hybrid propulsion systems can provide:
  1. Reduced fuel consumption and emissions
  2. Improved energy efficiency
  3. Lower machinery maintenance requirements
  4. Faster propulsion system response
  5. Reduced noise and vibration
  6. Greater operational flexibility through system redundancy
KOSCO SD supports clients throughout the development process, from initial concept and feasibility assessment to system integration, risk analysis, testing, commissioning, and performance evaluation.

KOSCO 354-MB
Next-Generation Marine Propulsion Battery System

The KOSCO 354-MB is a high-capacity lithium-ion battery cabinet developed for electric and hybrid vessels requiring scalable, megawatt-class energy storage.
​
The system combines a modular battery architecture, liquid thermal management, redundant battery monitoring, and marine-grade structural protection. Multiple cabinets can be configured to meet the propulsion and onboard power requirements of different vessel types.

Core Specifications
  1. Model: KOSCO 354-MB
  2. Battery chemistry: LFP or NMC, subject to project configuration
  3. Nominal system voltage: 768 VDC
  4. Rated capacity: 460 Ah per cabinet
  5. Nominal energy: approximately 354 kWh per cabinet
  6. System scalability: up to 20 cabinets
  7. Maximum nominal energy: approximately 7.08 MWh
  8. Thermal management: Liquid cooling with integrated heat exchangers
  9. Battery management: Redundant battery management and fault-monitoring functions
  10. Enclosure: Marine-grade corrosion-resistant construction
  11. System monitoring: Real-time monitoring of voltage, current, temperature, state of charge, and state of health
Electrical configuration, operating temperature, cycle life, charging rate, enclosure protection rating, and cooling requirements are determined according to the selected cell chemistry and project conditions.

​
Applications
​
The KOSCO 354-MB can be configured for:
  1. Electric and hybrid commercial vessels
  2. Ferries and coastal vessels
  3. Offshore support vessels
  4. Special-purpose vessels
  5. Research and survey vessels
  6. Auxiliary propulsion and onboard power systems
The number of cabinets and operating duration are determined according to the vessel’s propulsion load, operating profile, redundancy requirements, and available charging infrastructure.
