RBI Study for Manjung 5 Power Plant in Perak State, Malaysia

Fri, 03 January, 2020

TWI Services Sdn Bhd was awarded a contract for RBI assessment of the boilers and balance of plant equipment at the relatively new Manjung 5 Power Plant in Perak, Malaysia.

The Manjung 5 Power Plant is one of three ultra-supercritical coal fired power plants that is owned and operated by Tenaga Nasional Berhad (TNB), the largest electricity utility in Malaysia. The Manjung 5 Power Plant was commissioned in 2017.

TWI Services Sdn Bhd and TNB Labs Sdn Bhd recently entered into a collaborative agreement to provide RBI and asset integrity services to TNB’s thermal plants. This contract is the first of many contracts that is expected in the future. The Manjung 5 Power Plant was designed and built by the Sumitomo Corporation of Japan and Daelim Industrial Co. Ltd. of Korea, deploying the latest ultra-supercritical technology for new coal power plants.

This work started in August 2019 with a kick off meeting, data collection and a site visit. The contract scope of work involves the development of a scheme of inspection based on the design, operation and failure history of the plant. It is expected that the RBI assessment will investigate the likelihood of failure due to flaws damages, deterioration or degradation before, in combination with the anticipated consequences, a risk profile of each equipment component will be created.

This assessment will provide TNB with the detailed knowledge of the type and location of any failure, the rate at which failure may occur, and where failure would give unacceptable risk. Risk profiles for each equipment component will be generated and the inspection plan for each equipment component will be produced to provide confidence of future integrity.
