Client context
A multinational US-based corporation operating globally, with engineering and operational presence across Europe.
The company develops advanced subsea systems, where electronic components play a critical role in ensuring safety, reliability, and uninterrupted power delivery in demanding environments.
The challenge
Subsea environments required highly reliable electronics under strict physical and operational constraints.
Designing power electronics for subsea applications involves unique challenges, including extreme environmental conditions, strict safety requirements, and limited physical space.
The system needed to meet high-reliability standards while providing stable power delivery in conditions where failure is not an option.
At the same time, constraints related to component density, thermal performance, and electrical isolation made standard design approaches insufficient.
What it took to deliver results
To meet subsea requirements, the solution needed to:
- comply with high-reliability and safety standards
- ensure stable and efficient power delivery
- operate within strict space and density constraints
- maintain proper electrical isolation and thermal performance
- support long-term, failure-resistant operation in harsh environments
The design had to balance performance, safety, and physical limitations without compromising reliability.
The solution
Custom power electronics solutions were developed to meet the specific requirements of subsea systems.
The work focused on designing and optimizing key components, including custom magnetic elements, to achieve the required balance between performance, density, and isolation.
The system architecture was adapted to support multiple operating modes while maintaining consistent performance and reliability.
All elements were designed as part of a broader system where safety and power delivery are critical.
Engineering capabilities:
- Power electronics design and optimization
- Custom magnetic component design
- High-reliability system engineering
- Thermal and isolation design considerations
- Testing and validation for demanding environments
How it works
The platform integrates optimized power electronics components into a compact and reliable system architecture.
Custom-designed magnetic components support efficient power conversion while meeting strict isolation and space requirements.
The system is designed to operate across different modes, maintaining stability and performance under varying operational conditions.
Careful consideration of thermal behaviour, component density, and electrical isolation ensures long-term reliability.
Impact on operations
The solution enables reliable operation of subsea systems where consistent power delivery is essential.
By addressing constraints related to space, isolation, and performance, the design supports stable system behaviour even in demanding conditions.
Improved reliability reduces the risk of failure in critical environments, where maintenance or repair is complex and costly.
Business impact
The system delivered improvements across key areas:
- Enhanced reliability of subsea systems, reducing operational risk
- Optimized component design, balancing performance and space constraints
- Improved power delivery stability, critical for system safety
- Reduced risk of failure, in environments where downtime is costly
- Support for complex operating modes, increasing system flexibility
