  • 8. Offshore Wind – A New Challenge• New paradigm - Offshore wind is a different challenge to onshore – New entrants can take a leading role• Offshore wind demands new & innovative thinking – Environment is harsh – safety considerations are paramount – Development costs are very high – a different model for investment is required – Operators need to know that their turbines are reliable - exacting testing standards are required – Deployment is challenging – standardisation & simplified logistics required – Reactive offshore maintenance is expensive & prohibitive – Planned interventions require predictive technology Company confidential © DB Gear Systems Limited 8
  • 9. Imperative for changeExisting GBX performance• Most of the problems with the current fleet of wind turbine gearboxes are generic in nature, meaning that the problems are not specific to a single gear manufacturer or turbine model. Over the years, most wind turbine gearbox designs have converged to a similar architecture with only a few exceptions. (*)• The majority of wind turbine gearbox failures appear to initiate in the bearings. (*)• Problems that manifested themselves in the earlier 500kW to 1000kW, still exist in many of the larger 1 to 2 MW gearboxes being built today with the same architecture. (*)• Many of the gearbox problems are the direct result of institutional barriers that hinder communication and feedback during the design, operation, and maintenance of turbines. Hence, a collaborative is needed to bring together the various portions of the design process, and to share information needed to address the problems.(*) Musial W., and Butterfield S. “Improving Wind Turbine Gearbox Reliability “.

  • 10. Imperative for changeExisting offerings in the market• Normally, GBXs are manufactured in different facilities and locations. Then, they are sent Nacelle assembly plant.• Existing fix warranty periods for WTG components (normally 2 years).• Maintenance is currently done by WTG manufacturers. Wind Turbine technicians basically perform simple visual inspections every six months. Lack of GBXs specialists on site.• There are sporadic GBX assistances on site, performed by GBX manufacturers, when it is specifically required by WTG manufacturers or wind farm owners.• When a GBX is damaged, it must be replaced completely in most of the times.• Condition Monitoring Systems are rarely installed and, in those cases where it is, there is not a proper data analysis performed by operators at the remote control centre. Lack of knowledge.• GBX manufactures are reluctant to share data about performance and failure analysis.• Reactive response way of working with WTG OEMs and final users.

  • 11. David Brown approach to Offshore ‘Assured’ UK Gearbox Design & Supply Chain Partner to OEM’s looking to UK Round 3 development: • UK presence & established supply chain. David Brown is the only British company with the know-how & immediate capability to engineer, source, handle, manufacture & assemble the large components and functionally test very large MW gear units. • Product Innovation. Modular design for reliability and in nacelle maintenance. Gearbox flexible designs for 6 to 10MW wind turbine generators. Scope includes design, verification, manufacture and testing • Rapid Prototyping capability. Already prepared to meet 2012/13 Demonstrator sites. • High degree of engineering capability. DB has a long history in delivering mission critical solutions where the consequences of failure are extremely high; defence, marine, airspace and offshore oil & gas. • Willing to invest in the necessary facilities/assets.

  • 13. Tidal Energy• In December 2011, the 1MW Hammerfest Strøm HS1000 tidal turbine (1 MW) was successfully deployed in the North Sea, signaling a major step forward for the global marine renewable energy industry.• The HS1000 tidal turbine is fitted with a three stage David Brown gearbox which was designed, manufactured and tested at our Huddersfield facility and delivered in April last year.• Following successful load testing, the turbine was installed at the European Marine Energy Centre (EMEC) in Orkney. The HS1000 device will now enter a test period to confirm its performance and reliability, in preparation for larger scale production and deployment. Company confidential © DB Gear Systems Limited 13
