Submarine power cables are critical assets in the modern energy infrastructure all around the world, enabling the transmission of electricity across seas and oceans to connect countries, offshore wind farms, and isolated grids.
Ensuring their integrity, insulation, and long-term performance requires dedicated systems capable of precise pressurization and vacuum management.
At Brizio Basi, we design and build custom pumping plants engineered specifically to feed and pressurize submarine cables during installation, commissioning, and operation.
Our technology is developed to address the most demanding requirements of the electric sector:
• Continuous pressurization: Maintaining internal pressure within the cables to prevent moisture ingress and to preserve the dielectric properties of the insulation
• Vacuum feeding systems: Enabling degassing and fluid filling operations with high precision, ensuring uniform impregnation and air-free environments
• Automated control systems: Advanced PLC-based controls monitor all process parameters in real time, with data logging, alarm management, and remote supervision capabilities
• Redundant configurations: For mission-critical applications, we provide redundant pumping units and backup power systems to guarantee uninterrupted operation
Our solutions combine over 100 years of vacuum technology expertise with continuous innovation, supporting the electric sector in the development of reliable submarine interconnections that are fundamental to energy transition and grid resilience.
Applications:
• High-voltage submarine power transmission lines
• Offshore renewable energy systems (wind and solar)
• Interconnection of island and mainland grids
• Subsea oil & gas infrastructure requiring pressurized cable systems.
