Applus+ provides NDT for alternative and renewable geothermal energy provider in Hawaii
29/11/2021
Applus+ is providing non-destructive testing (NDT) services for an international energy company specialising in alternative and renewable geothermal technologies. Geothermal energy is a form of energy conversion in which heat energy from the Earth is captured and harnessed for electrical power generation.Applus+ is servicing the company’s geothermal energy operations in Hawaii, USA, by performing guided wave ultrasonic testing, high-temperature corrosion mapping (thermal scan) and pulsed eddy current (PEC) testing on approximately 4000 ft of injection lines at the plant facilities. In addition, ultrasonic testing was performed on the facility’s pumps.
Guided wave ultrasonic testing has been identified as an effective pipe-screening technology capable of assessing damaged areas over extended lengths in pipeline integrity inspections.
The technology used by Applus+ for (long-range) guided wave ultrasonic testing is designed with a minimum footprint of sensors and bands so that the asset integrity inspection can cover zones previously hindered by insulation or poor access.
PEC is a reliable way to survey ferrous pipes and vessels through their thermal insulation and protective coatings. The proprietary system RTD Incotest™ is an excellent option for prioritising corrosion under insulation inspections.
Together, guided wave ultrasonic testing and PEC support efficient maintenance operations by screening and prioritising further inspections and maintenance while eliminating the need for direct access.
As one of the global leaders in non-destructive testing and inspection services, Applus+ offers a wide range of capabilities to enhance and safeguard operations in the alternative energy market.
