Ensuring the seamless and continuous operation of wind turbines, while meeting each manufacturer’s specifications, is one of the biggest challenges facing the wind energy industry.

Exposed to severe mechanical loading and extreme environmental conditions, rotor blades are the most sensitive components of wind turbines. As a product of deep engineering knowledge, including composite material science and aerodynamics, regular inspections and proper maintenance are crucial to ensuring blades will reach or exceed nominal wind turbines design life. This is possible only through reliable damage assessments and preservation or restoration of the blades’ structural integrity.

With extensive experience and deep expertise in blade design and manufacturing, Compblades fits the bill when it comes to providing unrivaled blade repair services. The company has developed and manufactured several prototype wind turbines blades in the frame of R&D projects. The established know-how of Compblades and the applied R&D, gained from several collaborations in the novel field of blade inspection, repair, and reconstruction, give the company a competitive edge.

Compblades’ service portfolio encompasses blade inspection, damage assessment (ultrasonic), and repairs (up to structural recovers and reconstructions). All these services can be performed either on the ground, with aerial working platforms, or via rope access. In addition, by offering blade asset management services, the company helps clients minimize their operational costs and non-productive hours of their wind turbines.

“The output of our maintenance services is valuable for our clients,” says Theodore Kossivas, Owner of Compblades. “Our inspection and damage assessment reports can help them efficiently plan their blade repairs, and assist them in making important decisions, such as the replacement of a damaged blade.”

What steers Compblades ahead of other players are its executives, with more than 25 years of experience in the wind turbine sector, including turbine and blade load measurements, composite material constructions, and experimental mechanics. Their background in measurements, together with their practical experience, helps Compblades solve several complex blade problems reliably and quickly, by proposing and executing integrated repair solutions.

In one instance, Compblades reconstructed 19-meter blades for a client (2005), where the company replaced skins and seven-meter shear webs (internal load-carrying structure) and gluing the shear webs to the blades. The result was exceptional. The wind farm continued to operate without disruptions until 2019 repowering.

There are many repair cases where Compblades has performed damage assessment using ultrasonic, applied Reverse engineering, molds and replacement parts manufactured on-site and keep the weights and balance at the permissible levels of the manufacturer. Compblades successfully addressed complex repairs and provided the client with a complete and reliable solution in adverse climatic conditions, and in less than two months.

In the blade inspection and repair business since 1998, Compblades has established extensive know-how in the field of wind turbine blade engineering and composite materials, providing fast, reliable, confidential, and guaranteed solutions for each repair case without any technical problem. The company holds ISO 9001:2015, ISO 45001:2018, and ISO 14001:2015 certificates and is at the forefront in the novel field of blade repair and reconstruction.
