hrl: Increases PT YTL Power’s Plant Reliability and Revenues

PT YTL Power in Indonesia selected hrl: to assess the condition, fitness-for-service and remaining life of the power station, equipment and assets using a cutting-edge methodology.

Owners and operators of pressurised, rotating, or other plants, pressure, and piping are required to meet legislated compliance standards, including those addressing risk management and safety.

PT YTL Power operates a number of coal-fired power stations in Paiton, providing electricity to a developing Indonesia.

In response to compliance requirements, they needed to assess the performance and service life of the power station at various stages of service cycles. This included assessments of plant components such as processing lines, pipes, and vessels, in order to make informed decisions around planned outages and maintenance cycles to minimise plant downtime and maximise availability for reliable electrical output to clients.


HRL has worked with PT YTL for over ten years, providing metallurgical and materials services relating to the ongoing risk management of the power station assets in Paiton.

The inspection provided data that enabled PT YTL to develop strategic plans for extending the life of equipment, including services such as equipment integrity analysis, corrosion monitoring of structures and equipment, corrosion damage evaluation, and fatigue and creep damage to predict the parts of the plant most at risk of failure.


The Plant Life Assessment service provided by hrl: allowed PT YTL to make informed decisions to maintain high plant availability, which resulted in optimal electrical output, increased productivity, and improved reliability of electrical supply to clients. These services also enabled PT YTL to make informed decisions around managing resources and risk, without additional costs or drops in revenue as a result of unexpected plant or asset failures and unplanned outages.
