Availability Assurance - Operations
The ARTIS Live application is one of the asset management plans and it covers the risks to production availability. Although this is only a single dimension, it does provide a uniform yardstick and captures all planned and unplanned downtime and all capacity changes and changes to the operating envelope, as might arise from project expansions and de-bottlenecking, maintenance and inspection, capacity swings and capacity declines, and other sources. With it, the organization can control the link between the production availability targets and the alternative risk responses and ensure that, over time, its assets are capable of delivering its targets.
The intent of the ARTIS Live application is for the organisation to optimise its responses to the risks and opportunities identified in section 4.3 and maximise the lifetime value of their assets. It builds around a transparent and quantitative computer model of the assets and provides the means to take on board all risks to production availability, tie together the many elements of asset improvement programs that make the system work cohesively, provide the line of sight, and close the learning cycle, for all levels of management and all disciplines.
Its key advantage is that it provides a corporate model, quantified and validated, accessible and understandable for all, up-to-date with the current condition status, for reviewing and optimising the risk responses. Assurance is built into every business process and ARTIS Live provides an agreed platform for that. ARTIS Live takes a scientific and integrated approach through risk modelling, optimisation and reporting, with a mathematical background based on probability theory and statistical modelling.
The ARTIS Live application monitors the production availability of the integrated system, aimed at giving Operations an improved and faster response capability in case of any unfolding risks to production and keep the organisation informed on a continuous basis, enabling a pro-active risk management approach. ARTIS Live provides a full platform for defining, measuring and testing the acceptable risks, maximising production availability and managing the vulnerability to possible capacity shortfalls.
The significance of the ARTIS Live application to maintenance is through its interfaces with reliability centred maintenance (RCM) and with maintenance optimisation. The preparations of these interfaces can already start during project development and may include the identification of the relevant failure modes and maintenance and inspection strategies, crystallising in the maintenance reference plan. Together, these document the functional requirements for the implementation of the maintenance management system. The availability assurance program provides guidance in this area that has traditionally been wrought with difficulties and inconsistencies.
The collected historical downtime data can be used for maintaining a ranking of the criticality of the individual failure modes. This provides an objective and quantified basis for focusing further RCM studies and maintenance improvement initiatives, fully closing the Do - Check - Improve learning cycle.
The asset management system must also include a plan for managing the asset integrity. Immediate focus on possible areas of technical risk is key for ensuring safe assets. The asset integrity policy is, in one sentence, to establish that the assets are safe, to know why and being able to show that, not at dicrete points in time (during audit rounds) but continuously and visible for all staff, management and stakeholders. This aims to achieve that assets are safe to operate and maintain and at the same time provide an objective and quantified basis for minimising planned and unplanned inspection, testing and maintenance downtime. Asset integrity management builds on and completes the traditional risk based inspection (RBI) approach.
This is a revolutionary new approach for the management of risk based inspection and corporate reporting that takes full advantage of the new IT integration opportunities with fully graphical user interfaces and has proven its value with large, complex and aging facilities.
