Procurement & Project Questions

What types of vessels and platforms does Black Frog Elektro work on?

We handle electrical installation, panel building, and commissioning for cargo carriers, tankers, naval combat support ships, HVDC offshore wind platforms, world-class cruise ships, road ferries, and the world's most sophisticated superyachts — both new builds and refits.

Where does Black Frog Elektro deploy?

We deploy internationally. Around 95% of our operations are carried out abroad — primarily in The Netherlands and across European shipyards — supporting shipyards, naval programs, offshore wind installations, and luxury yacht builders. Our 80+ specialists travel to wherever the hull is under construction.

What is the full scope of services offered?

End to end: electrical engineering and design, cable pulling, equipment mounting, equipment connection, panel building, fiber optic installation and certification, cold wire testing, and systems commissioning. We deliver as one contractor, with one accountability line, from schematic to sea trial.

Can Black Frog Elektro work as a subcontractor for larger marine electrical integrators?

Yes. We work both as a primary marine electrical contractor and as a trusted specialist subcontractor for leading European integrators like Royal Van der Leun, Alewijnse, Eekels Technology, Hoogendijk Electric, and Royal Bodewes. Our deployment model is flexible.

How quickly can a project team be mobilized?

Typical response from inquiry to a mobilized team is 4–8 weeks, depending on team size and scope. For specialist tasks like fiber optic certification or commissioning support, we can mobilize smaller teams within 1–2 weeks. Contact us for a project-specific timeline.
