Performing maintenance services at the right time

Aligning procurement time-frames with the asset health index.

The asset health index (AHI) is a rating that outlines the asset condition and performance level, and this naturally deteriorates over time. Maintenance activities intend to improve the AHI, thus ensuring the availability and reliability of assets. Therefore, it is important for maintenance to be done at the right time to prevent unplanned breakdowns and a disruption of services.

One of the causes for delayed asset maintenance or even a lack of asset maintenance relates to the procurement of service providers and/or the material requirement for maintenance. Procurement processes typically take anywhere from one to three months, or more. This is due to a variety of challenges such as, incorrect technical specifications, poor market response, incompetence of employees, and so on. Therefore, it becomes possible that an initially routine maintenance service escalates into a different requirement, for example, the asset may, in the interim, have deteriorated so badly that a replacement is necessary instead of maintenance/service.

The deterioration of assets over time means that procurement processes need to happen faster than it takes an asset to reach a new level of breakdown/failure. This is highly relevant for organizations that adopt ‘run-to-failure’ policies – meaning that assets are not maintained during their lifecycle but are left to operate until a point of failure, at which point action is taken. In this scenario, the questions present as, when will the assets fail, and when should procurement processes for maintenance or replacement be initiated? The extent to which these questions are considered by various organizations in their operations is uncertain.

There are two types of maintenance, i.e., unplanned (e.g., breakdown, emergency, etc.) and planned. The latter can be classified into three sub-categories, namely: time-based, condition-based, and risk-based. Many organizations strive to minimize unplanned maintenance and it is agreed that knowledge of the asset condition is critical to a sound maintenance plan/schedule. The essential facilitator for planned maintenance is a ‘Condition Assessment’ which helps organizations to assess an assets actual health index, life expectancy, the remedial actions needed, and when to act.

Kurumeng assists Clients with walk-through inspections and an engineering performance analysis of their properties, plant, and equipment. The outcome is a detailed ‘Condition Assessment’ report on the infrastructure’s health status, outlining opportunities for improvements and the related costs.

If you would like to take advantage of our building walk-through condition assessment, don’t hesitate to get in touch – we’d love to help!
