In every industrial plant and in particular in a Giant Brownfield Oil Plant, asset integrity management plays a crucial role both in day-by-day activities and in future operations, and it helps to maximize the company value. This paper presents an innovative digital tool to monitor, track and manage the Process and Maintenance Override Switch (POS and MOS). It includes email alert, historian tracking and it is the basis of the Management of Change (MOC) process of a giant brown oilfield. This new digital tool relies on the increasing data availability and on the huge opportunity that data democracy enables to production engineers, operators, and plant manager. It combines DCS raw data, event and alarm list, signal condition and inhibits with a storage data tool and the Digital Oilfiled (DOF) to create an Integrated Operation Center (IOC) with a section focusing on barrier panel and asset integrity. Focusing about the POS and MOS system, the tool read the real time data from the Integrated Control & Safety System (ICSS) and store them in the IOC where the data are accessible to all the production, maintenance and HSE personnel. These data are rearranged in order to focus the attention on risks, safety barriers and related mitigation through the entire plant. The IOC will automatically send alert email one hour before the shift ending. Control room supervisor together with the Central Control Room (CCR) operators can check all the POS and MOS tracked during the shift and remove the inhibits that are no necessary to the operations. Thanks to IOC, plant manager and control room supervisor can track new inhibits and report them to the maintenance team or to the production engineers to confirm the proper risk analysis and mitigations actions and initiate the MOC procedure, if needed. MOC are needed to meet the brownfield plant evolution and operating/safety requirements according to internal operations Procedure Instruction (OPI), local and national regulations and international standards. The IOC and the DOF integrate also the alarm list, in order to improve Alarm Management System and Alarm Rationalization/Reduction activities. It highlights the most frequent alarms and create a collaborative environment in which production, maintenance and automation team can work together to reduce the alarm number and frequency. This new digital management tool gives a strong contribution to production engineers, plant manager, CCR supervisor and maintenance team to maximize transparency and safety for people, environment and asset. Focus the attention on the process overrides highlights every moment the barrier status panel of the plant and supports the management of change process in a Giant Brownfield Oil Plant creating a collaborative environment based on data availability and data democracy. |
