Wind turbine blade IRM

James Fisher Marine Services delivers innovative wind turbine blade inspection, repair and maintenance (IRM) services.

Rotos 360, part of James Fisher Marine Services (JFMS), has the expertise to identify and repair damage, excessive wear and other potential issues that can effect wind turbine blades. Rotos 360 combines turn-key boat service and blade platform technology in order to provide the safest, most comprehensive and cost effective access to offshore wind turbine blades.

Turbine blades have to be perfectly aerodynamic to function effectively, but damage can cause erosion as they move through the air at speeds of up to 200mph, dramatically reducing their efficiency. Routine wind turbine blade repair is a time-consuming process which has always been highly weather dependent.

Rotos 360 provides experienced industry certified personnel for:

  • Wind turbine blade inspection
  • Wind turbine blade repairs
  • Wind turbine installation - onshore and offshore
  • O&M service
  • Retrofits
  • End of warranty inspections
  • Vessel provision
  • Rope access


Innovative wind turbine cured blade repair - RENUVO UV

The company has also helped to develop the Gurit Renuvo ultra violet (UV) cured blade repair method - RENUVO UV. The RENUVO UV method cures blades 25 times faster than the conventionally used Epoxy curing, cutting the curing time for a large repair from six hours to five minutes.  

The UV system is also effective in temperatures as low as 5C and as high as 30C in conditions of up to 90% humidity. This increases weather windows for repairs, significantly reducing any downtime.

This innovative and efficient method has resulted in significant time saving, reduced costs and improved safety through the use of Rotos's unique suspended work platforms. 

Features and benefits of the RENUVO UV blade curing method include: 

  • Significantly reduced downtime and associated costs
  • Increased safety with the Rotos 360 unique suspended work platform
  • Working temperatures can be 5-30 degrees centigrade
  • Fast curing: 25 times faster than Epoxy curing
  • Clean materials: no toxic vapours emitted during curing


Highly trained personnel:

Rotos 360's operations are all undertaken by highly experienced technical teams. As part of its team specification, each blade technician must have at least four years referenced experience in blade repair.

Rotos 360 also operates long-term training programs, enabling personnel to train from intermediate level up to the company standard.
