Xelcor - the core of foundation connection
Overcoming complex technical challenges in offshore wind turbine deployment is crucial for industry operators. Increasing pile sizes and moving wind parks farther out to sea help boost energy production and lower the Levelized Cost of Energy (LCoE). However, these advancements challenge traditional pile foundation connections. Water depth, salinity, currents, winds, and seabed conditions all impact foundation design and installation, affecting risk and durability. Current foundation connection systems lack scalability, adaptability, and pose high HSE risks during installation.
Design. Production. Integration. Seamlessly Delivered.
Xelcor, our wind turbine foundation connection system, is transforming the offshore wind industry. Formerly known as Smart PU Slip Joint, it reduces costs in production, installation, and scalability while simplifying maintenance. At Rosenxt, we support our clients through every critical phase of the foundation connection lifecycle. In the design phase, we collaborate closely with turbine and steel engineers to simulate load cases, optimize geometries, and fine-tune polyurethane properties. During production, we manufacture the customized PU plates using advanced formulations tailored to the specific environmental and structural conditions. Finally, in the integration phase, we ensure precise on-site integration of the plates at the steel manufacturer's location. Our process is seamlessly integrated into the steel fabricator’s workflow, enabling smooth collaboration and coordination. This end-to-end service guarantees performance, quality, and reliability at every step and enables faster installation with fewer specialized vessels on-site, thanks to a connection technology designed for real-world offshore challenges.
Your Benefits
Scalable design for any turbine foundation size
Even load distribution
Easy and safe installation
Maintenance-free
Easy offshore installation
Xelcor tackles common challenges. This innovative system consists of high-performance polyurethane (PU) elastomer plates placed between connecting conical sections of a monopile (MP) and transition piece (TP), or even of segmented monopiles. Applied onshore, the plates ensure easy offshore installation while protecting the anti-corrosion coating from steel-on-steel friction in the overlapping zone.
Polyurethane Formulations at Rosenxt
With decades of experience, we have perfected PU solutions for various applications in harsh environments requiring high abrasion resistance, chemical resistance and high flexibility of the material used. Xelcor is the latest innovation, ready to tackle offshore wind challenges for operators worldwide.
Xelcor offers numerous advantages:
- Scalability: No limits to size or shape of turbine foundation
- Load distribution: Eliminates hot spots and withstands high local stresses.
- Easy and safe mounting: Plug and work
- Durability: Built to last the turbine's entire lifecycle with no maintenance required
- Flexibility: The connection technology can be installed underwater, in splash zones, and above water without additional work
- Design freedom: Design and application of PU plates reduce steel usage and allow greater flexibility in terms of tolerances and overlapping zone
