Do you believe offshore charging infrastructure will significantly help decarbonize the maritime industry?
Stillstrom has contracted Semco Maritime to manufacture the critical equipment rooms required for offshore charging infrastructure. The containers will house essential power and safety systems to support vessel electrification.
Why it matters
These units function as the nerve center for power distribution and safety across offshore charging sites, marking a key step in expanding green energy infrastructure for maritime fleets. The hardware ensures that high-voltage distribution remains stable and secure in demanding offshore environments.
Stillstrom signed the manufacturing agreement on September 23, 2026, following the completion of the design phase earlier that year. The project targets completion by spring 2027.
The players
Stillstrom
A developer of offshore charging infrastructure focused on decarbonizing the maritime sector through automated power solutions.
Semco Maritime
An international engineering and construction firm specializing in projects for the energy sector including offshore infrastructure.
Siemens
A global technology conglomerate providing electrical engineering components including the switchgear and control systems required for this project.
The details
The local equipment room is a containerized unit designed to house transformers, switchgear, and integrated safety systems. Siemens will serve as a subcontractor to provide the electrical switchgear and control technology. Once manufactured, these units are installed directly on monopile or hang-off structures at each charging site to manage power flow to vessels.
Timeline
Early 2026: Semco Maritime completed the initial design phase for the equipment room.
September 23, 2026: Stillstrom and Semco Maritime signed the formal manufacturing agreement.
Spring 2027: The manufacturing of the first local equipment units is scheduled for completion.
The Home Front
This development follows a pattern of industrial infrastructure investment driven by the International Maritime Organization's Greenhouse Gas reduction strategy. It reflects a broader trend of shifting maritime logistics toward electrified, land-connected power sources.
While this hardware serves the commercial shipping industry, it represents the foundational infrastructure needed to eventually support wider maritime electrification. Owners of vessels or those following port-side environmental regulations should track the expansion of these charging sites.
The takeaway
The move toward offshore power hubs is a critical step in enabling large-scale maritime electrification. Interested parties can monitor updates on the spring 2027 delivery target to understand the pace of offshore charging deployment.
