Advanced Programme on Electrification

About This Course

1. Understanding typical load demand profiles:
- Typical motor and starter characteristics in marine and offshore systems
• Alternating Current (AC) & Direct Current (DC) motors
• Motor starters and drives (Silicon Controlled Rectifier, Direct-online, Electronic and Variable Speed Drive)
- Marine propulsion system (inverters, inductors, propellers & gearboxes) – understanding typical propulsion configurations, normal operation load profile, and transient inrush currents for inverters and motors
- Hotel load profile – lighting, general power, air conditioning (sized for 2 crew, 12 passengers) – estimation of maximum demand for a given allowances for diversity

2. Power Generation and Distribution
- AC generators - Diesel Engines
- Solar panels and power inverters
- Fuel cells and power converters
- Emergency Power Requirements for marine vessels

3. Energy Storage Systems in a hybrid vessel
- Calculation of power and current demand requirement for battery systems
- Selection of Lithium-ion battery capacity and configuration
- Selection of power inverter for battery bank
- Safety requirements for explosion risk and fire suppression
- Requirements for Battery Management System (Overview on current/voltage/temperature sensing; contactor control; protection; interface/communications; State of Charge, energy and power estimation functionalities)
- Shore-to-ship battery charging

4. Electrical installation design for hybrid marine vessels
- Components of a power distribution system –transformers, main switchboard, distribution panels, final circuits, protective devices, cables, grounding
- Special requirements for marine electrical installations
- Selection of protective devices and cables for Alternating Current (AC) & Direct Current (DC) systems
- Power management system and control logic (Direct Current (DC) -link solution for diesel-electric drive train)"
