Type of contract: Project based fee for professional services

Duration of contract: 7 weeks

Summary:

Transfield Worley Solutions conducted a review of the spares analysis, procurement and inventory management activities at the client’s main operating site.

The primary objective was to optimise the spares support function to achieve higher rates of equipment availability.

Transfield Worley Solutions was able to offer comprehensive professional and technical services, calling on broad experience across several industries, to assess the client’s spares requirements.

By applying our combined knowledge of the best practices in maintenance, Transfield Worley Solutions was able to tailor the analysis criteria and consequent recommendations around the specific needs of the client.

SPARES ANALYSIS – COGENERATION PLANT

Scope & Approach:

The Transfield Worley Solutions approach was to:

• verify the location and condition of the clients equipment and plant against the asset register
• assess the criticality of the cogeneration plant mechanical equipment
• apply industry accepted spares assessment methodologies to determine the optimal spares inventory quantities and range
• determine the life cycle costs of ancillary equipment and non-critical items for evaluation of insurance spare quantities

Outcomes & Benefits:

The spares optimisation review directly benefited the client by:

• demonstrating that it was more cost-effective, given the operating and support scenarios, to carry parent equipment as spares rather than components or sub-assemblies
• enabling the client to make informed decisions about spares quantities and range based on the criticality of plant and equipment
• identifying equipment for which spares should be managed using service agreements with spares suppliers to achieve maintenance budget reductions
• identifying opportunities for suppliers to hold consignment stocks of critical and non-critical spares to improve equipment down-times
• reducing the value of the spare inventory held locally by 20%, thereby further reducing the maintenance budget
