Abstract
AbstractFraming reliability, availability and maintainability (RAM) aspects are critical for an engineering design, as RAM is concerned with the sustained capability of a system throughout its useful life. RAM analysts are responsible to consider both functional and dysfunctional behavior of a given system beyond the perspective of system designer. However, the system concept baseline developed by RAM toolset is often a partial view, which is either too abstract when preparing RAM analysis or too overloaded when integrating RAM analysis with design process. Such practice may not give systemic insights of the design concept, considering specific subsea design challenges such as limited accessibility and requirement for automate control. For this reason, it is of great importance to ensure an effective and sufficient communication between the domain of design and domain of RAM. Integrating with a well‐known engineering discipline, such as systems engineering (SE), may help analysts to create the collaborative design environment necessary to control the design risks for a system with high complexity. This article proposes a new framework that links SE with RAM engineering by connecting relevant concepts and models used. A novel subsea design concept is offered as a case study to demonstrate the key changes in subsea design activities for addressing RAM with the proposed framework.
Highlights
Reliability, availability, and maintainability (RAM) is concerned with the sustained capability of a system throughout its useful life
RAM analysis based on feedback from existing legacy systems imposes constraints on systems requirements, architecture, and design.7(p97) managing RAM is often viewed as a separate activity in many subsea engineering practices, and the relationship to other established engineering frameworks, such as systems engineering (SE), are often not developed
The selection of design concept should consider the maintenance and spare parts costs related to the revealed failure modes and the risk for loss of profit and income related to measurement uncertainty, where all the losses are converted into a monetary unit, that is, Norwegian kroner (NOK)
Summary
Reliability, availability, and maintainability (RAM) is concerned with the sustained capability of a system throughout its useful life. Due to lower oil prices and changing field conditions, the Norwegian-based O&G industry is increasing the installation of subsea equipment to accommodate pressure assistance, O&G separation, and water treatment.[16] The marinization of topside technology (eg, fixed or floating facility) offers several benefits, such as increasing recovery from the field and saving costs associated with manning and maintaining the platforms. Hereafter, such innovations for improving current production solutions are referred as new subsea design.
