James Fisher Renewables has conducted an innovative trial of Ship-to-Turbine (STT), an oil change system set to significantly improve safety, efficiency and reduce down time in offshore wind turbine gearbox oil changes.
The trial was recently performed on an offshore wind farm off the Norfolk coast. James Fisher Renewables successfully demonstrated the STT system by completing the entire evacuation, flushing and re-fill of the gear oil system in less than four hours total pumping time per turbine.
The STT system employs proven vacuum, preheating and filtration technology to transfer the oil from a self-contained deck-mounted unit, through umbilical hoses directly eliminating the need to fill and hoist containers via the nacelle crane. In comparison oil change operations undertaken in the traditional manual method can take in the region of two days.
Alan Heslop, Business Development Manager at James Fisher, commenting on the trial of the STT system, said: “The trial successfully demonstrated the innovative method of changing offshore turbine gearbox oil. We worked closely with our partner, Chemical Corporation, to adapt, marinise and develop their onshore Sage Oil Vac technology for offshore applications, creating a flexible system suitable for any oil volume and type.”
Ship-to-Turbine has the potential to revolutionise offshore oil change operations, whilst increasing the safety of technicians, reducing the risk of pollution and significantly increasing operational efficiency.
The development of STT further underscores the commitment of James Fisher Renewables to the offshore wind sector through innovation and the deployment of UK technology and skills.
