James Fisher has signed a memorandum of understanding (MoU) for the use of motion compensated gangways in the development of the ULSTEIN SX221 Diamond SOV.
Under the agreement, it will partner with Uptime International (Uptime), the global leader in safe motion compensated logistics solutions for the offshore wind industry.
The news follows the unveiling of the Diamond Consortium’s ULSTEIN SX221 Diamond SOV concept in June 2022.
With James Fisher representing the Diamond Consortium, a collaboration with Graig and support from DNV and Ulstein Design Solutions, the SOV will exclusively utilise Uptime’s motion compensated gangways for safe transportation of technicians and equipment between vessels and turbines.
The MoU sees James Fisher secure access to critical equipment for its SOV newbuild programme, bolstering its commitment to help the UK’s offshore wind sector meet its capacity target of 50GW by 2030.
Continuing to operate with environmental goals in mind, Uptime’s innovative Digital Ecosystem has a long-standing track record for delivering improvements on efficiency, energy consumption and emissions, while upholding the highest safety standards, according to the company.
James Fisher group business development director Jim Hey said: “Based on current project pipelines at least 37 new SOVs are required to meet UK offshore wind demand.
“With over 1500 UK employees in offices across including Lowestoft, Barrow-in-Furness, Grimsby and Aberdeen, along with our maritime heritage spanning 175 years, James Fisher has the right people in the right places to bring this innovative vessel to market, placing the UK at the centre of the global offshore wind revolution.
“The logistic system is a critical element of SOV design and usage.
“The combination of James Fisher and Uptime’s expertise and capabilities will shore-up availability of supply with a future-proofed design for gangway technology upgrades.
“We are thrilled to be working with Uptime and look forward to the next steps in development.”
James Fisher will have access to Uptime’s full suite of capabilities, including its recently announced Digital Ecosystem, including digital tracking of personnel and equipment through the logistic system on to the wind turbine and the use of automated pallet robots.
