Huisman has reached an important milestone in the development of a new jacking system, tailored for the growing offshore renewables energy market. The company has completed a Factory Acceptance Test for the first Huisman Jacking Gearbox, which will be part of the jacking system.

The Huisman Jacking System, available in a range of models, is specifically designed for wind turbine installation jack-up vessels, taking into account the requirements of today and tomorrow. The system contains a dedicated proprietary control system, which optimises the system’s load distribution, specifically for turbine and foundation installation.

Huisman has teamed up with its long-term supplier of gearboxes for offshore equipment, German based O&K Antriebstechnik, part of the Bonfiglioli Group. An important aspect of a successful delivery of the gearbox has been the Factory Acceptance Test (FAT), consisting of multiple tests under motion at O&K’s test facility in Hattingen. Upon delivery of the gearboxes to one of its production facilities, Huisman will continue with full-load jacking demonstration trials.

Huisman enters jacking market

Huisman has extensive experience in the application of large-scale drive systems in offshore applications that include large pinions, large gearboxes, and large amounts of power, combined with sophisticated control systems. With the new jacking system, the company will apply its experience to the jacking market.

‘We are proud of achieving this important milestone for our new range of jacking systems,’ says Cees van Veluw, Product Manager Cranes at Huisman. ‘This will further enable the implementation of the systems in vessel designs that may emerge in the years to come. The interest of vessel owners, operators and designers has encouraged us to apply our knowledge and expertise to this.’
