Safety for a gas processing facility starts with preventive maintenance. For Santos Limited, operating 150 gas fields and 90 oil fields in the Cooper Basin of Australia, the job is huge. And expensive. To manage facilities efficiently, without impacting performance and productivity, Santos Limited is evaluating new opportunities such as virtual asset management. Using information from databases, ...asset management processes and 3D models to plan, build and maintain complex facilities, including material requirements and workforce needed for repair or expansion work, is referred to as Building Information Modeling (BIM). Companies implementing BIM programs have found they are able to make more timely and informed maintenance decisions, resulting in overall lower operating costs.
With the availability of online data, BIM is becoming a more popular method to administrate the complete life-cycle of large infrastructure facilities. However, information needed is not always available in digital form. For example, original architectural drawings may not match the current structures, creating an inaccurate basis for the 3D modeling required for the BIM model.
Santos’s main hydrocarbon processing facility in Moomba, South Australia, first commissioned nearly 50 years ago, has definitely expanded since originally built. It currently receives production from surrounding oil and gas fields through approximately 5,600 kilometers of pipelines and flowlines via 24 oil and gas satellite facilities. Natural gas liquids are recovered via a refrigeration process in the Moomba Plant and sent together with stabilized crude oil and condensate through a 659-kilometer pipeline to Port Bonython near Whyalla, South Australia, while sales gas is sent from Moomba to Adelaide via a 790-kilometer pipeline and to Sydney via an 1160-kilometer pipeline. Up to date information would definitely be needed to create 3D models of the Moomba facility.
