History
KCI Offshore Engineering has had a key role
in shaping the offshore industry since 1984
Founded in the Netherlands, we have built our reputation in the oil & gas industry by delivering innovative engineering solutions for platforms, modules, and complex steel structures.
Expanding into offshore renewables
With the global acceleration towards sustainable energy, our expertise naturally expanded into the offshore renewables sector. KCI therefore made a deliberate and strategic shift to include focus on offshore renewable energy in addition to offshore oil & gas projects. Today, we stand as a trusted specialist in offshore foundations, combining decades of experience with future-focused engineering
Joining the Sif Group
In 2021, KCI became part of the Sif Group, one of Europe’s leading manufacturers of offshore foundations. This integration has strengthened our ability to offer design-to fabrication alignment and has deepened our industry insight and practical execution knowledge.
A strong foundation since 1984
Throughout our history, KCI has maintained a project execution-oriented organisation, ensuring quality through efficient project delivery. Through early involvement of our consultants and in an industry which is constantly changing, we can recognise the need to adapt and prepare for emerging opportunities and changing conditions.
