What KCI the engineers does
KCI Offshore Engineering is a Rotterdam-headquartered structural engineering consultancy founded in 1984, specializing in fixed-bottom offshore assets. The firm operates four interconnected service lines: offshore wind turbine generator (WTG) foundations, offshore topside foundations for platforms and substations, offshore decommissioning, and adjacent areas covering offshore green hydrogen, carbon capture and storage topsides, custom offshore equipment, and observation wheel engineering. Core technical work is anchored in SACS software-based structural analysis and includes expertise across monopiles, jackets, tripods, gravity bases, and platform substructures, with alternative verification techniques for complex structural details that streamline Marine Warranty Surveyor approvals.
The company's business model is professional services-based, generating revenue through project-based engineering and design engagements with offshore operators, developers, and fabricators. Work spans the full asset lifecycle from early concept and feasibility through basic and detailed design to fabrication support, transport and installation engineering, and decommissioning. Pricing is quote-based and negotiated per project with no public disclosure of rates or benchmarks. KCI has been a wholly-owned subsidiary of Sif Group since 2021, operating independently while leveraging the parent's WTG fabrication capabilities for design-to-fabrication alignment.
The company serves a concentrated base of European enterprise clients, with disclosed engagements including TenneT (2GW offshore grid program), Dragados Offshore (LanWin2/BalWin3 HVDC platforms), Siemens Energy (525kV HVDC systems), Huisman (Monopile Storage & Transport System), and Scaldis SMC (Eni Hewett decommissioning). Geographic focus is on the Netherlands and Germany, with customer concentration weighted toward offshore wind developers, oil & gas operators, and specialized marine contractors. Customer acquisition is relationship-driven, executed through dedicated section heads, proposal managers, and direct sales contacts at [email protected], with project wins coming from competitive bids and direct enterprise engagement.

- Saipem: Major offshore EPCI contractor with engineering, fabrication, and installation capabilities for fixed and floating offshore structures. Overlaps with KCI on jacket and platform design and decommissioning engineering scopes.
Direct peers
- Ramboll: Engineering consultancy with a strong offshore wind foundation and substructure practice, particularly in Northern Europe. Directly comparable to KCI in client base, project type (fixed-bottom foundations), and design-only delivery model.
- COWI: Danish-headquartered engineering consultancy with deep offshore wind foundation design heritage, including monopile and jacket design. Competes with KCI for TenneT-adjacent and broader European offshore wind foundation scopes.
Regional players
- Subsea7: Subsea engineering, construction, and services contractor active in offshore wind and oil & gas decommissioning. Comparable to KCI on offshore installation engineering support and structural engineering for subsea and offshore structures.
Emerging players
- ISC Consulting Engineers: Smaller offshore structural engineering consultancy with foundation and platform design expertise in the North Sea market. Closest in scale and specialization to KCI as a direct fixed-bottom foundation design peer.
