Piping Corrosion Circuit
Piping corrosion circuit or Corrosion loop / Piping Circuitization and Corrosion Modelling, is carried out as part of either a Risk Based Inspection analysis (RBI) or Materials Operating Envelope analysis (MOE). It is the systematization of the piping components versus failure modes analysis into materials operating envelope. It groups piping materials / chemical make-up into systems / sub systems and assigns corrosion mechanisms. These are then monitored over the operating lifetime of the facility. This analysis is performed on circuit inspection results to determine and optimize circuit corrosion rates and measured thickness/dates for circuit components. Corrosion Circuits are utilized in the Integrity Management Plan (IMP) which forms a part of the overall Asset integrity management system and is an integral part of any RBI analysis. Many times a "system" will be a broad overview of the facilities process flow, broken by stream constituents, while a circuit level analysis break ...

Corrosion Loop
Corrosion loop(s) are systematized analysis "loops" used during Risk-based inspection analysis. Both terms “RBI Corrosion loops” or “RBI corrosion circuits” are generic terms used to indicate the systematization of piping systems into usable and understandable parts associated with corrosion. Systematized piping loops or circuits are systems used in Risk Based Inspection analysis to assess the likelihood and consequence of failure. Other systematization may also prove useful, such as, i.e. inspection, consequence, materials of construction and chemistry. The system (or sub systems) maybe used to identify, pressure / temperature, subsequent failure mechanism and possible failure rate. They may be based upon Construction drawings, Process Flow diagrams or Piping & Instrument diagrams as required. Each loop or circuit maybe identified using a unique code, with description about; process, material & degradation mode, material, cladding, C.A, specs. See system model comes un ...

Risk Based Inspection
Risk Based Inspection (RBI) is an Optimal maintenance business process used to examine equipment such as pressure vessels, (QOC) quick opening closure - doors, heat exchangers, and piping in industrial plants. RBI is a decision-making methodology for optimizing inspection plans. The RBI concept lies in that the risk of failure can be assessed in relation to a level that is acceptable, and inspection and repair used to ensure that the level of risk is below that acceptance limit. It examines the Health, Safety and Environment (HSE) and business risk of ‘active’ and ‘potential’ Damage Mechanisms (DMs) to assess and rank failure probability and consequence. This ranking is used to optimize inspection intervals based on site-acceptable risk levels and operating limits, while mitigating risks as appropriate. RBI analysis can be qualitative, quantitative or semi-quantitative in nature. Probability of Failure (PoF) is estimated on the basis of the types of degradation mechanisms o ...

Integrity Management Plan
Integrity Management Plan (part of an asset integrity management system) is a documented and systematic approach to ensure the long-term integrity of an asset or assets. Integrity management planning is a process for assessing and mitigating risks in an effort to reduce both the likelihood and consequences of incidents. Asset integrity plans are maintained and reviewed regularly so that they: *Optimize operational and capital expenditures *Ensure adoption of best-in-class practices *Assist management of risk *Increase shareholder, senior management, regulator and public confidence *Identify risks, conducting assessments, taking preventive actions and implementing mitigate measures An effective IMP should contain: *A process outline – details the process envelope (temperature pressure and velocity) in which the system operates and any critical parameters that must be followed. Also states process chemistry and contaminants that are encountered *A threat identification list- In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asset Integrity Management
Asset Integrity Management Systems (AIMS) outline the ability of an asset to perform its required function effectively and efficiently whilst protecting health, safety and the environment and the means of ensuring that the people, systems, processes, and resources that deliver integrity are in place, in use and will perform when required over the whole life-cycle of the asset. The technical aspects of AIMS are illustrated in Figure 1. Originally developed in the UK, Asset Integrity Management was the result of a collaboration between the HSE and leading oil and gas operators resulting in a series of reports (Belfry Report) and workshops, the outcome being a group of documents called Key Programmes (KP Series), currently publicly available. An Integrity Management System should address the quality at every stage of the asset life cycle, from the design of new facilities to maintenance management to decommissioning. Inspections, auditing An audit is an "independent examinat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Design Creep
A design is a plan or specification for the construction of an object or system or for the implementation of an activity or process or the result of that plan or specification in the form of a prototype, product, or process. The verb ''to design'' expresses the process of developing a design. In some cases, the direct construction of an object without an explicit prior plan (such as in craftwork, some engineering, coding, and graphic design) may also be considered to be a design activity. The design usually has to satisfy certain goals and constraints; may take into account aesthetic, functional, economic, or socio-political considerations; and is expected to interact with a certain environment. Typical examples of designs include architectural and engineering drawings, circuit diagrams, sewing patterns and less tangible artefacts such as business process models. Designing People who produce designs are called '' designers''. The term 'designer' generally refers to someone who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Petroleum Institute
The American Petroleum Institute (API) is the largest U.S. trade association for the oil and natural gas industry. It claims to represent nearly 600 corporations involved in production, refinement, distribution, and many other aspects of the petroleum industry. Much of its work has been dedicated to the advancement of climate change denial and blocking of climate legislation to defend the interests of its constituent organizations. The association describes its mission as "to promote safety across the industry globally and influence public policy in support of a strong, viable U.S. oil and natural gas industry". API's chief functions on behalf of the industry include advocacy, negotiation and lobbying with governmental, legal, and regulatory agencies; research into economic, toxicological, and environmental effects; establishment and certification of industry standards; and education outreach. API both funds and conducts research related to many aspects of the petroleum indus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corrosion Engineering
Corrosion engineering is an engineering specialty that applies scientific, technical, engineering skills, and knowledge of natural laws and physical resources to design and implement materials, structures, devices, systems, and procedures to manage corrosion. From a holistic perspective, corrosion is the phenomenon of metals returning to the state they are found in nature. The driving force that causes metals to corrode is a consequence of their temporary existence in metallic form. To produce metals starting from naturally occurring minerals and ores, it is necessary to provide a certain amount of energy, e.g. Iron ore in a blast furnace. It is therefore thermodynamically inevitable that these metals when exposed to various environments would revert to their state found in nature. Corrosion and corrosion engineering thus involves a study of chemical kinetics, thermodynamics, electrochemistry and materials science. General background Generally related to metallurgy or material ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
