Origin Energy is Australia's largest energy retailer, with approximately 4.3 million customers with electricity, natural gas and LPG. The Australia Pacific LNG (APLNG) Project is a coal seam gas to liquefied natural gas, to deliver a cleaner, greener sustainable energy source. The APLNG Upstream project was encountering technical integration issues for plant & equipment, and multi-disciplinary issues that arise from sub-projects during design, construction and commissioning.
Nova Systems was engaged to develop a common understanding of the integration need, and then to provide a plan and toolset to start to manage the integration risk. The Nova Systems integration Process Model provided a basis for assessing the integration risk and filling gaps on the development project. The Systems Engineering specialists conducted a gap analysis which included an integral risk assessment. The risk assessment was to be used to confirm and address the main risks first, as well as inform the client of the risk they face. Following the first recommendation, Nova Systems developed an Integration Strategy for the project with the integration objective being to effectively manage the staged connection of assets and services to ramp-up gas production and yield the APLNG production capability, with an acceptable level of risk.
The Integration Strategy provided the desired understanding of integration, identifying the approach to integration stages, as well as roles and responsibilities; using the existing Interface Management function as a building block. As integration was also firmly tied in to the established project development life-cycle, Nova Systems developed an Integration Management Plan, providing the “how to” solution. This clearly highlighted the staged-integration approach, and further detailed roles & responsibilities. As the project was well underway, not all of the Nova Systems recommendations could be implemented.
This highlights the need for integration to be addressed up front in order to provide maximal value.
