The Next Generation Monopile-Gripper & Upending Tool is compatible through modular design with all monopile diameters planned up to 2025 and covers monopiles up to 1,800 tonnes, with flange up to 2,100 tonnes deadweight. The tool can be used variably whether on jack-up or floating installation vessels!
High installation speeds
The optimised dead weight (95to of the lifting gear in relation to the load to be lifted) and the new, field-proven design enable a rapid monopile installation by significantly increasing the erection speed. Lifting operation times between 60 and 90 minutes are possible, with pure uppending requiring only between 10 and 15 minutes!
High process reliability
Only one crane is needed to erect the tool. Even with an unfavourable position of the monopile or with an inclined mounting angle, a controlled lifting process is guaranteed.
Even in floating installation, the tool arm, which can be swivelled around all axes, allows an inclined pull with up to 5° angular rotation and relative movement of the crane boom. An optional catcher and guide system completes the setup. The robust guide system prevents uncontrolled collisions or snagging. This significantly improves control when removing the UET (Upending Tool) from the monopile flange after installation.
- More speed in the erection process.
- Less bad weather waiting time.
- Greater deployment intervals possible!
Thanks to the patented solution, no more damage to the flanges is possible:
- A dynamic clamping system optimises the load introduction into the monopile flanges.
- Additional lower grippers are optionally available to further reduce deformations and stresses.
- Reduction of stress by 25% in the flange area through targeted force transfer (from the flange) into the monopile web.
This offers the best possible protection for monopiles to prevent life-shortening overvoltages!
Offshore service support
We are also on hand for difficult load cases. We offer offshore service support with our own teams as required, as well as professional spare parts management and maintenance monitoring, including remote maintenance and service back office. This means that we can also react at short notice in the event of a malfunction.
