Smart PU Slip-Joint

Overcoming complex technical challenges in offshore windmill 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.

Scalable design for any turbine foundation size

Even load distribution

Easy and safe installation

Maintenance-free for greater safety

Rosenxts SlipJoint solution consists of high-performance polyurethane (PU) elastomer plates placed between connecting conical sections like monopile (MP) and transition piece (TP).

Easy offshore installation

The Smart PU Slip-Joint for wind turbine foundations, tackles common challenges. This innovative system consists of high-performance polyurethane (PU) elastomer plates placed between connecting conical sections like monopile (MP) and transition piece (TP). Applied onshore, the plates ensure easy offshore installation while protecting the anti-corrosion coating from steel-on-steel friction in the overlapping zone.

The Smart PU Slip-Joint 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
