“…The technical assessment module involves the application of condition assessment tools to determine current physical and functional health status of an asset. Risk assessment methodologies have widely been used for this purpose in some industries (e.g., see Palkar and Markeset, 2012;Liu et al, 2014;Carvalho et al, 2015). On the other hand, probabilistic safety assessment (PSA) models such as analytical unavailability and unreliability models have also been employed in the nuclear industry to determine current health status of safety related systems (e.g., see Martorell et al, 1999;Kancev et al, 2011;Kancev and Cepin, 2012;Martón et al 2015).…”

“…Ramuhalli et al (2012) applied PHM techniques to assess and predict the RUL of nuclear reactor components. Our proposed framework adopts an assessment rating approach as in references Palkar and Markeset, 2012;Liu et al, 2014 andCarvalho et al, 2015. However, the approach utilized in this study is more quantitative and accounts for greater number of key factors in LE technical assessment.…”

“…Vaidya and Rausand (2011) proposed a model for technical health assessment of critical assets for LE and applied it to a subsea raw seawater injection system. Liu et al (2014) presented a framework for managing LE of offshore oil and gas installations in Chaina's Bohai Bay field. The framework mainly focuses on technical assessment of safety related systems for extended operations.…”

One of the major decisions in management of the industrial assets is to ensure the feasibility of life extension process for safety critical components when they reach end-of-life. Most of the existing life extension decision-making models are restricted solely to either "technical" or "economic" feasibility analyses that may lead to inaccurate results or incorrect conclusions. In this paper, a comprehensive life extension feasibility assessment framewok by taking into account both the technical and economic considerations is developed. The proposed technoeconomic model for life extension of safety critical elements consists of three phases: preparation, assessment, and implementation. The technical assessment part of the framework incorporates all aspects of data collection and review, screening and prioritization of safety critical elements, condition assessment, estimation of remaining useful life, and risk analysis, while the economic assessment part deals with cost-benefit analysis. The decision to qualify a safety critical element for continuous operation beyond its service life is made based on a "life extension measure (LEM)" which is calculated by combining two indexes of "equipment health condition" and "economic added-value" obtained respectively from the technical and economic assessments. The model is applied to support the life extension decision-making procedure for water deluge systems in offshore oil installations. The results of the study show that the model is highly capable of assisting asset owners to evaluate the technical and economic benefits of extending the service life of components.
