Hydropower enjoys inherent technical, economic, and environmental benefits that make it an important part of both the present and future of world energy. This is particularly true for developing countries, where growing demand for power is complemented by significant untapped hydro potential. Meanwhile, for countries with an established hydropower capacity, increased plant life and assured safety with the lowest environmental impact are key factors.
Hydropower has unique structural integrity problems compared with other industries. This stems from issues such as concrete encasement of components, the physical size of components and low temperature operation. And, while hydropower plants benefit from long operating lives, this brings its own issues with ageing asset management.
TWI can assist with maintaining the operating efficiency of existing hydropower plants through defect assessment and mitigation, while also offering specialist inspection and a confidential, impartial, and independent service in a competitive industry. This operational support is built on years of experience, and TWI’s weld repair procedure and development capabilities mean that the life of existing facilities can be extended by delaying or even removing the need for the expensive replacement of current resources. This single-point access to the world-class structural integrity, materials, inspection, repair, and fabrication expertise is just part of what TWI can provide.
TWI’s proven risk based asset life assessment and optimisation methodology, RiskWISE, is ideally suited for use on pressure systems. When deployed as part of an asset investment planning strategy it could realise benefits for hydropower similar to those seen when employed in other industries.
TWI has a demonstrable track record in penstock, spiral case, bucket and wicket gate integrity, inspection and repair development supported by advanced inspection and NDE techniques, and you can find out more via our NDT, Engineering Critical Assessment, coatings for wear protection and weld repair web pages. Our experience includes Francis, Pelton and Kaplon turbines.
Finally, should things go wrong, TWI also has the capability to effect independent and confidential failure investigation, allowing a plant to return to operation as soon as possible.
