ZITON provides specially designed vessels that bring flexibility and efficiency to replacing major components on offshore wind turbines.

With the average offshore wind turbine size predicted to reach 6 MW by 2020,  vessels need to be designed for an even more demanding future.
All of our experience and know-how gained from service and major component replacements on more than 400 wind turbines has influenced the design and manufacture of these vessels.

The combination of these vessels and our insight gives us unparalleled flexibility to offer our customers the most efficient process.
We have the industry’s first self-propelled, heavy-lift barge with a permanently mounted, telescopic crane capable of working at a height of 100 metres – J/U WIND.

Furthermore, we have two more purpose-built jack-up vessels – J/U WIND SERVER and J/U WIND PIONEER –  capable of servicing even larger turbines in deeper waters, higher winds and on a variety of seabeds.

Made for offshore wind O&M
Effective and early planning of operations and maintenance processes can help reduce lost power production by up to 60 per cent

Our O&M professionals bring thousands of hours of practical experience in all aspects of O&M, from crew transfer to component replacement to health and safety measures.
We also manage Provision of Appointed Persons, seafastening design and MWS approvals.

Not a blade is left unturned when you plan your O&M future with us.
Ask us to help you save time and money in planning your O&M strategy and processes. In addition to long-term strategic planning, we can help with:
•  site-specific assessments

For offshore wind decommissioning operations, we offer tailor-made solutions for removal of met masts, wind turbines and foundations. 
All operations are executed with a high focus on safety, cost efficiency and as little environmental impact as possible.
ZITON also offers offshore installation support services such as commissioning of turbines and offshore substations.

Using jack-up vessels for installation support has a number of advantages including: access to cranes, a stable platform, highest safety and comfort of living quarters, swift repositioning by use of vessel’s DP system, large deck space for storage, workshop and stores facilities below deck.
Combined with the experience and skills of the ZITON organisation, our purpose-built vessels offer a clear edge to the available alternatives.

Our team handles the whole process from planning of the safest and most sustainable decommissioning method to recycling of the removed components.
Expanding our business into decommissioning and installation support services
We are serious about ensuring offshore wind is a truly viable option for delivering to the world’s energy needs.

Massive investments have already been made in offshore wind infrastructure, and effective operations and maintenance of this infrastructure is critical in ensuring the industry delivers on its promise.
Through the work we do and the services we provide to the industry, we are intent on helping the industry reduce the costs of energy production by maximising operating time.
But there is work to be done. The cost of energy from offshore wind needs to be reduced by 40 per cent by 2020 from 2014 levels. Innovative and long-term strategic change and investment is required
Our strategic purpose
We believe in the future of offshore wind energy
