Still as an example, consider how, in the study of service level, it is important to know the availability of machines, which again depends on their reliability and maintainability. Various techniques are such as Reliability Block Diagrams (RBDs) and Fault Tree Analysis (FTA) can be used to determine Reliability. FEED – At the FEED stage, critical equipment’s are identified which could cause significant production losses. © 2016, Southwest Petroleum University. The new approach covers all phases of the new product development process and is aimed at producers of complex products like safety instrumented systems (SIS). A majority of the reliability studies and the theoretical models focus their attention to system consisting of small consumable (non-repairable) components. within the context of a model. The main purpose of this work is to propose a new approach to evaluate maintenance strategies. Reliability, Availability, Maintainability (RAM) analysis allows you to simulate the entire lifetime performance of an asset in terms of availability, production efficiency and profitability.

Reliability, Availability and Maintainability Study (RAMS) RAMS refers to Reliability, Availability and Maintainability Study which is a decision making tool used to identify how to increase the availability of the system, and thus increase the overall profit as well as reducing the life cycle costs. Compliance to the international Standards such as IEC 61508 and IEC 61511 are imperative to meeting the Functional Safety requirements for many processes and have formed part of the quality management systems of many companies. A RAM analysis would normally be conducted on these critical equipment’s in order to optimise the equipment configuration and identify the requirements of any further spares or equipment redundancies in order to optimise the availability of the system. The study was based on the analysis of the behaviour of states defined for each individual parts and component of reciprocating compressor and also aimed to identify and evaluate the effects of RAM-type factors and was conducted in collaboration with a private company that, for privacy reasons, will be named RC company.

Proof Testing is one of the main requirements to ensure that Functional Safety is maintained throughout the operational phase. The focus will be mainly system reliability, availability and maintainability (RAM) analysis. Juntao Zhang. FSES are able to us various methods in identifying SIL targets; qualitatively by Risk Graphs, semi-quantitatively by Layers of Protection Analysis (LOPA) or fully quantitatively by Fault Tree Analysis (FTA). FSES have their own in-house RAM analysis tool built based on our vast experiences of conducting RAM studies. The goal of the chapter is to present RAM analysis as a link Reliability, Availability, Maintainability, Supportability Study TheEuropean Circular Energy-Frontier Collider Study (EuroCirCol) project has received funding from the European Union's Horizon 2020 research and innovation programme under grant No 654305. The discipline’s first concerns were electronic and mechanical components (Ebeling, 2010). This guidance directs Services to implement RAM practices that ensure effective collaboration between the requirements and acquisition communities in the establishment of RAM requirements. However, these concepts can be expanded to different fields. Students with a master's degree in Reliability, Availability, Maintainability and Safety (RAMS) are attractive in the job market. Lundteigen et al. This chapter demonstrates the application of RAM (reliability, availability, and maintainability) analysis to process industries by providing a case study of a natural-gas processing plant. A RAM study at this point would allow the client to identify performance targets that must be met by the equipment, which can be used as part of the equipment design specification during procurement. Functional safety activities are most effective by integration into a well-established and proven quality management system.

Reliability, Availability, Maintainability and Safety focuses on the following sustainable development goals: 7 Affrodable and clean energy: by ensuring the safety and deliverability of offshore oil and gas, wind power- and hydro power facilities. Detailed Engineering – At the detailed engineering stage it is likely that the design is frozen with minimal changes. A RAM study (Reliability, Availability and Maintainability) assesses the production system in question, whether it is already in operation, or still in the design phase. Provision of Functional Safety Services in line with the Phases and Activities detailed in the Safety Life-cycle is an area in which our consultants are able to demonstrate experience and expertise. Active and Reactive maintenance programs are required in order to ensure reliability of equipment and thus reliability and availability of Safety Instrumented Functions. Challenges and Approaches for New Requirements. The main objectives of a RAM analysis, is for it to be used as a decision making tool to increase the availability of the system, and thus increase the overall profit as well as reducing the life cycle costs (inclusive of the cost of maintenance, lost production, operating etc). 1.2.1 Reliability Reliability is the probability of an item to perform a required function under stated conditions for a specified period of time. Learning objectives : Discharge and Dispersion is often required to evaluate the consequence of identified hazardous events. Reliability Services. 1.1 Background of Study Reliability, availability and maintainability (RAM) model is an engineering tool that delivers the safety in operation and production and aims to identify the component or failure modes within the system where improvement can be achieved. Reliability, Availability and Maintainability (RAM) Study for Gas Processing Plant ... Webniar - Strategies & Methods for Reliability, Availability, Maintainability & Safety - Duration: 43:37. This paper presents the most relevant aspects and findings of a study conducted for assessing the operational performance of a reciprocating compressor system package installed and used in the oil and gas' industries. The origins of contemporary reliability engineering can be traced to World War II. The Oil & Gas industry has continuously increased its requirements and together with the high complexity of technological systems and the higher competitiveness of markets, has compelled providers to implement adequate management strategies for these systems in order to improve their availability and productivity to meet those more demanding criteria. In this study, three criteria called reliability, availability and maintainability (RAM) have been employed to compare to future maintenance strategies.
