Global Wind Service

What Global Wind Service does

Global Wind Service A/S (GWS) is a Denmark-based, privately held provider of wind turbine installation and service solutions, headquartered in Fredericia and majority-owned by the Norwegian Fred. Olsen Ocean group. Founded in January 2008 by Lars Bo Petersen and Michael Nielsen, the company deploys more than 1,700 technicians across 39 nationalities through 13 business units on four continents, delivering projects in 40+ countries with documented involvement in approximately 90% of Europe's offshore wind installations over time.

GWS's service portfolio spans the full wind asset lifecycle: onshore and offshore turbine installation, pre-assembly works, scheduled and unscheduled service and maintenance, blade maintenance (via rope access, platforms, and jack-up vessels), repowering and life-extension, statutory inspection and repair, and high-voltage services (10kV-400kV). Underlying technical capabilities include proprietary GWO-certified training delivered through the GWS Academy in Dobra, Poland, the Kinetic Corporate Software inspection management system, and access to offshore installation vessels through the Fred. Olsen Windcarrier joint venture.

The business operates as a project-based professional services organization serving two customer segments: wind turbine OEMs (Vestas, Siemens Gamesa, GE Renewable Energy, Nordex) and wind farm developers/owners (RWE, Northland Power, Shell). Revenue is generated through hourly rate and lump-sum multi-year service contracts on a project-by-project basis, with no publicly disclosed pricing. The company holds UKAS Category C, LEEA, IRATA, GWO, and ISO 9001/14001/45001 certifications, and is expanding its geographic footprint through targeted offices in the UK, France, Spain, Taiwan, Japan (via DENZAI partnership), and the United States.
