DNV GL provides market overview and detailed review of specific manufacturers and technologies to clients worldwide.
Clients call on these services for a variety of reasons. Some require an overview of the turbine market to help them decide which turbine models to include in their wind farm development plans; others want to purchase turbines for a specific project. There are also clients that are planning the acquisition or financing of a wind farm project, or thinking of taking over a turbine manufacturer. Whatever the client’s motive, and this list is not definitive, the main aim of the turbine consulting work is to provide an overview of the technical risks associated with the technology and/or the business transaction in question as well as an understanding of the possible mitigation measures.
DNV GL’s turbine consulting service is made up of three basic elements. The first is a wind turbine market overview, including a review of a particular manufacturer's market share and of specific turbine models available worldwide or by region. This is usually supported by a turbine manufacturer overview with comments on the manufacturer’s capability to manufacture, install and service wind turbines compared to industry standards, previous performance and willingness to support products. Finally, a more detailed technical review covers comments on the turbine technology compared to industry standards, detailed component discussion, turbine design verification status according to IEC standards or the like, previous performance, a technical risk summary and classification of the turbine model as proven or unproven technology according to pre-determined criteria. If a specific project site is identified, DNV GL can also comment on the suitability of a specific turbine model for installation on that site.
Reviews of the terms and conditions associated with the same of turbines, or operational warranties associated with performance, are typically provided as part of a due diligence study, but can also be performed as part of a turbine review.
