Do you believe offshore charging infrastructure will significantly help decarbonize the maritime industry?
Stillstrom signed a manufacturing agreement with Semco Maritime to produce the local equipment rooms for its offshore charging infrastructure. The containerized units will house power distribution, communication, and safety systems.
Why it matters
The local equipment room serves as the nerve center for offshore charging sites, ensuring safe and efficient power delivery to vessels. This contract marks a key step in advancing the infrastructure needed to support maritime decarbonization efforts.
The containerized equipment room acts as a central hub housing transformers and switchgear. These units are designed for installation on offshore monopile or hang-off structures.
The players
Stillstrom
This company develops offshore charging solutions intended to power vessels with clean electricity.
Semco Maritime
This international project engineering company specializes in the energy sector and offshore infrastructure.
Siemens
This global technology firm provides electrical engineering and infrastructure solutions including switchgear systems.
The details
Semco Maritime is tasked with manufacturing the unit after completing the design phase earlier this year. Siemens will participate as a subcontractor to provide the necessary switchgear and control systems.
Timeline
Early 2026: Semco Maritime completed the design phase for the local equipment room.
September 23, 2026: Stillstrom and Semco Maritime signed the manufacturing agreement.
Spring 2027: The manufacturing of the equipment room is scheduled for completion.
Roadmap
This manufacturing agreement signals a broader industrial push toward standardizing offshore charging technology. It follows the technical integration path established by the Stillstrom automated cable control system.
This development indicates that offshore charging hardware is moving from the design phase toward physical implementation. It sets the stage for future maritime logistics where vessels can recharge at sea instead of returning to port.
The takeaway
The move demonstrates how specialized manufacturing partnerships are required to turn complex offshore power designs into reality. Standardizing these containerized units will be essential for the scalability of maritime charging networks.
