How can we support?

At KCI Offshore Engineering, we provide proven structural and consultancy expertise to ensure the safe, efficient removal or repurposing of offshore assets. Leveraging decades of experience in both the design and assessment of offshore structures, we guide operators through every stage of the decommissioning life cycle: from feasibility and risk assessments to detailed engineering for lift, transport and dismantling. By blending deep structural insight with practical operational know-how, we deliver solutions that work in the real world. Our alternative verification techniques for critical, complex details, coupled with streamlined Marine Warranty Surveyor (MWS) approvals, minimise offshore exposure while maximising safety, efficiency and cost control.

We support you through:

  • Decommissioning concept development
  • Comparative removal method studies
  • Lift and transport engineering
  • Structural reassessment and cut-point optimization
  • Temporary structures and rigging design
  • Life extension assessments for re-use or repurposing
  • Regulatory and technical documentation support
  • Consultancy and owner’s engineering during planning and execution

Sales pitch

Smart, safe, and sustainable structural solutions for offshore decommissioning. KCI brings over 40 years of offshore engineering experience to the evolving world of decommissioning. Our independent perspective, hands-on mindset, and deep structural expertise allow us to support
operators in developing solutions that are safe, cost-efficient, and aligned with environmental goals.

We understand that no two platforms are the same and that successful decommissioning requires detailed technical planning, operational coordination, and flexibility in execution. With KCI, you gain a reliable partner who knows how to strike the balance between compliance, cost, and sustainability.
