KCI the engineers

KCI the engineers B.V., operating as KCI Offshore Engineering, is a Dutch engineering consultancy specializing in the design, engineering, and consultancy of fixed offshore structures. Founded in 1984 and headquartered in Rotterdam, the company provides end-to-end services across the project lifecycle, including concept development, detailed design, fabrication and installation support, and decommissioning for platforms, foundations, and related infrastructure.

Its core expertise covers structural engineering for offshore wind turbine generator (WTG) foundations such as monopiles, topside substructures including jackets and substations, and modifications for energy transition projects like carbon capture and storage (CCS) platforms. The firm has expanded from its origins in oil and gas to renewables and sustainable energy applications, supporting projects in Europe and Asia.

Since its acquisition by Sif Group in 2021, KCI operates as a subsidiary, enabling integrated design-to-fabrication solutions particularly for monopile foundations. With approximately 80 experts and over 40 years of experience, it positions itself as a specialist provider of pragmatic, buildable engineering solutions in the offshore energy sector, contributing to projects such as platform modifications for the Porthos CCS initiative in the Netherlands.
