Practical Solutions

At Ketz B.V., we deliver heavy lifting solutions that combine safety, efficiency, and structural integrity. By optimizing rigging configurations and lift point designs, we minimize the need for structural reinforcements while maintaining robust safety margins. Our tailored engineering solutions include custom spreader beams, shackles, slings, and other rigging components to ensure seamless execution. In parallel, our transport engineering focuses on optimized grillage design and structural verification to protect assets during transit. Through advanced analysis and simulation of transport and sea conditions, we safeguard structural integrity while reducing downtime and operational costs.

Our installation services are designed to ensure precise, safe, and efficient offshore deployment. We develop custom installation guides and bespoke tooling tailored to the specific requirements of each project. By integrating rigorous motion engineering analysis, we simulate waves, wind, and current effects to predict structural behavior during installation. This proactive, data-driven approach allows us to mitigate risks before offshore execution begins. The result is reliable, regulation-compliant installations that enhance safety, streamline operations, and extend the lifecycle of offshore infrastructure.

Our Naval and Ship Design Engineering services provide comprehensive solutions from concept development to detailed design and classification support. We specialize in hydroelastic analysis to evaluate vessel performance under complex wave and load interactions. Using advanced CFD simulations, we optimize hull forms and improve hydrodynamic efficiency. Our team delivers robust structural design, hydrostatic calculations, and full compliance with classification society requirements. We also support barge design, conversions, and modifications, ensuring safe, efficient, and cost-effective marine assets.

Our Structural Engineering services cover global hull assessment and advanced structural analysis for offshore and marine structures. We perform jacket and topside analyses, delivering safe and optimized solutions for demanding offshore environments. Our expertise includes foundation design tailored to site-specific geotechnical and loading conditions. Through linear and non-linear FEM analysis, we evaluate structural performance under extreme and operational loads. We also conduct detailed fatigue verification to ensure long-term integrity, reliability, and regulatory compliance.

At Ketz B.V., we approach offshore  decommissioning with a smart, cost-conscious, and highly efficient mindset. We act as your engineering partner, not just a supplier, working closely with you to optimize every phase of the project. Our focus is on minimizing offshore preparation days and reducing the need for costly bespoke tooling. By applying precise engineering and only the necessary safety factors, we avoid unnecessary reinforcements and additional offshore work. This results in safer operations, reduced risk exposure, lower costs, and improved overall project efficiency.

We believe successful decommissioning projects are built on aligned incentives and shared responsibility. That is why we work with a fixed-fee model, ensuring our goals are fully aligned with yours from tender to execution. By delivering thorough engineering assessments early in the process, we take ownership of the final product and provide clarity from the start. Our meticulous preparation and optimization reduce delays, streamline execution, and shorten project timelines. Together, we simplify complex offshore lifting and decommissioning projects, making them safer, faster, and more successful.

  Robust Solutions for a Dynamic World

Understanding the dynamic and challenging nature of offshore operations, our solutions are engineered for durability and adaptability. We design grillage and seafastening systems to withstand extreme conditions, reducing the need for offshore welding and minimizing operational time, ensuring your project stays on schedule.

Rapid Seafastening for Decommissioning

For offshore decommissioning projects, speed and reliability are critical. Our innovative designs enable seafastening in less than 6 hours, setting a new industry benchmark. By streamlining installation processes, we enhance safety and efficiency, delivering robust solutions that save time and reduce costs.

  Accurate 3D modelling

Creating accurate models is the basis of detailed engineering and reliable results in the real world. Determining CoG and total weight accurately, as well as having correct dimensions, ensure perfect execution.

Drafting

The 2D drawing is the engineers communication tool with the outside world and thus the most tangible product of all the previous steps. Delivering high quality technical drawings is an art form that requires care and attention. An art form we practice with pride.
