THE MISSING LINK IN HYBRID SUBSEA POWER SYSTEMS HAS ARRIVED
Project Progress: Manufacturing & Qualification Milestones Manufacturing and qualification of the DC-AC Inverter are currently underway at Advanced Mechatronics in Germany, leveraging an existing product from their portfolio. Thanks to this foundation, the team has already completed Q1 qualification, allowing them to fast-track development and move directly into Q2 testing. Following a successful DCFO (Direct Current Fibre Optic) testing phase in September at Alcatel Submarine Networks in Paris, the project has reached a key validation milestone. This achievement confirms the inverter’s performance in real- world subsea environments and reinforces its appeal to customers seeking advanced, reliable DC- based power distribution solutions.
What’s Next: System-Level Integration and Final Testing Following successful qualification, the DC-AC Inverter will be integrated into the PCDM for Electromagnetic Compatibility (EMC) testing. This will include coordinated testing alongside the PDPM, CEM, and PCM, ensuring seamless performance across the entire power distribution and control system. This final phase will deliver a fully qualified PCDM solution, ready to meet the evolving needs of subsea operations and support the industry's transition to more flexible, efficient, and future-ready power architectures. The DC-AC Inverter isn’t just a technical upgrade—it’s a strategic enabler for hybrid power systems, unlocking new possibilities for subsea control and distribution.
As subsea infrastructure evolves to meet the demands of modern energy systems, Baker Hughes is introducing a breakthrough solution: the DC-AC Inverter, a key enabler for seamless power conversion in subsea environments. Housed within the Power and Communications Distribution Module (PCDM) and integrated with a third-party inverter, this technology bridges the gap between DC-powered topside systems and AC-powered infield networks—ensuring compatibility, performance, and power integrity in one streamlined package. Why It Matters: Supporting the Shift to DC Architectures The DC-AC Inverter programme is designed for customers transitioning to—or preferring— DC-based topside-to-subsea distribution architectures, while still leveraging field-proven AC Subsea Control Modules (SCMs). This hybrid approach allows operators to modernize their power systems without sacrificing reliability or legacy compatibility. By enabling DC-to-AC conversion directly within the PCDM, the solution simplifies integration, reduces complexity, and supports a wider range of subsea configurations.
