Development of an ISO 55000 compliant central management framework for asset care plans within a multi-technology portfolio of renewable energy power plants in the South African energy sector

[摘要] ENGLISH ABSTRACT: The conventional philosophies adopted to develop Asset Care Plans (ACPs)(tactical and non-tactical maintenance plans) for Renewable Energy PowerPlants (REPPs) are often not sophisticated and therefore adequate to optimiseasset performance. There is a need to utilise more sophisticated methodsto develop ACPs using philosophies such as Reliability Centred Maintenance(RCM) combined with economic evaluation methods such as Asset Life-CycleAnalysis (ALCA) or other considerations such as obsolescence. Specialisedskills are often required to assist in developing ACPs. The Renewable Energy(RE) industry in South Africa (SA) is in its infancy and thus offers a shortage ofcompetency within the RE sector. The competency challenges combined withlimited information sharing by Original Equipment Manufaturers (OEMs) createsa potential void in the capability of SA Asset Managers to develop ACPsfor RE assets. Once ACPs have been developed they need to be continuouslymanaged in terms of development, planning, execution and optimisation. Thework planning and control, continuous improvement and competency managementfunctions play a key role within the overall management function butneed a business process to underpin the function and identify support tools. The SA RE projects often have complex management or ownership structures.A management team could consist of an Asset Owner or shareholders, an AssetManager managing the asset overall and the OEM performing the maintenancefor an extended period as part of a service agreement. Having a clear AssetManagement (AM) framework can create an operating environment where allstakeholders can work towards common goals and a Line-of-Sight can be establishedbetween the Organisational Strategic Plan (OSP), AM objectives,AM strategies, asset planning and the daily AM activities. Cases exist wherea single Asset Manager or management organisation is responsible for managinga portfolio of RE projects constituting different technologies such as windand solar Photovoltaic (PV). This provides an opportunity to centralise AMand other organisational functions. Exploiting central management platformsand resources are furthermore becoming increasingly important for AM serviceproviders and project developers to remain competitive in the RE marketwhere costs and tariffs are continuously declining.The problem is that there is no framework aligned to an AM framework suchas ISO 55000, that can guide Asset Managers to develop and manage ACPsfor a multi-technology portfolio of REPPs. The study addresses the problemby developing a framework and business processes which can be used to establishthe core strategic and planning requirements of the ISO 55000 series ofstandards; to use sophisticated maintenance philosophies to develop, execute,manage and optimise adequate ACPs; to facilitate continuous improvementwith an emphasis on competency management to address scarce skills andoptimise ACPs; and to understand the possibilities regarding centralisation,while remaining aligned with the ISO 55000 series AM framework.The study developed a Central Management Framework (CMF) which wasvalidated using face and user validation. The CMF was found to be substantiallysuitable and able to address many of the existing challenges within theSA RE sector.
