Engineering Maintenance & Support

Engineering maintenance and support is an essential service over the life of an operation and includes scheduled maintenance services as well as support for breakdowns and failures. We follow a logical fault finding process to identify the root cause and where applicable provide recommendations to reduce the likelihood and/or consequences of the event occurring again.

Through our engineering maintenance and support services, Orana Engineering strives to build long term relationships with our clients.  Building long term relationships is an integral part of our business model and business philosophy and it gives us the best opportunity to be a resource that is valued by our clients.  We believe that this value comes from over time better knowing our clients' sites, systems and people, which from this knowledge we can provide engineering services that are tailored to our clients' requirements.

Our engineering support services include control systems support, training and commissioning as well as client engineer services.  We provide engineering maintenance and support for coal, metalliferous, oil and gas clients as well as industrial and commercial clients.
