Client Background

Nampak Glass is a leading glass manufacturer producing glass bottles for the food and beverage industry. The state-of-theart manufacturing facility in Roodekop, Gauteng operates three furnaces and nine parallel production lines to produce a total of 260,000 tons per annum. This output consists of bottles in a variety of customised shapes, sizes and colours.

Nampak Glass asked Martec to investigate implementing a service level agreement (SLA) based on GRC (guide for maintenance and testing of electrical power system equipment) that would be linked to the insurance requirements.

Martec studied the GRC document and adopted the process into the electrical services SLA, which will cover the insurance requirements.

Key Challenges

Ensure that Martec testing and condition assessments provided to Nampak Glass adhere to the GRC maintenance guide.

Implement the system cost effectively with the required periodic visual inspections, testing and online condition assessments.

The Nampak Glass electrical plant is unique and can only be maintained during colour changes, therefore it is important to implement non-intrusive online condition monitoring systems without impacting production.

The key is …
the right information at the right time.
