SCHIEDAM, the Netherlands — Huisman has completed a Factory Acceptance Test (FAT) for its first jacking gearbox for a jacking system designed for current and future offshore wind turbine installation jackup vessels.
A proprietary control system is designed to optimize the load distribution for turbine and foundation installation.
Huisman is working with gearbox supplier O&K Antriebstechnik, part of the Bonfiglioli Group, for the development.
The FAT involved multiple tests under motion at O&K’s test facility in Hattingen, Germany. Once Huisman has received the gearboxes at one of its production facilities, it plans to continue with full-load jacking demonstration trials.
Among the features of the jacking system are
- Two gear versions – L and XL – suited to vessel designs produced by various independent design companies, allowing owners to freely choose the vessel’s hardware of preference.
- Static pinion loads up to 800 metric tons (L) or 1,000 MT (XL)
- Flexible suspension method for smart integration with the vessel design
- Potential to achieve leg preload capacities beyond 30,000 MT, depending on leg layout and the system’s number of layers
- Control provided by Huisman’s proprietary Variable Frequency Drive control system
- Integration of power system with various makes of cranes, and with power grids supplied by different electrical integration companies.
