Project Overview
OEC Power & Control delivered the detailed design of the complete electrical and control systems for a new offshore support vessel with hybrid diesel-electric propulsion. The system combines conventional diesel generators and batteries to reduce emissions and fuel consumption.
Scope of Work:
- Hybrid system allowing battery-assisted operation and peak shaving
- Design of MV and LV power distribution networks
- Power management system (PMS) and integrated vessel automation
- Detailed design for MCCs, transformers, switchgear, and cable routing
- Compliance with marine class society requirements
Key Design Elements:
- Hybrid system allowing battery-assisted operation and peak shaving
- Redundant power supply and fail-safe design
- Shore power integration for port operations
- Load analysis and dynamic simulation for system optimisation
Impact & Benefits
- Reduced fuel costs and environmental impact
- Improved vessel manoeuvrability and reliability
- Compliance with emissions regulations and class standards
- Future-ready design supporting potential full electrification
