Criticality Analysis of Platform Supply Vessel (PSV)
AuthorAzad, Marziyeh Bagheri
The oil and gas industry has expanded consistently from land operations to inland waterways and then to offshore. A platform supply vessel (PSV) is an important element of offshore supply logistics. Hence, its acceptable level of availability performance is highly demanded. Identification of critical components provides essential information for improving and optimizing the maintenance management, spare part strategy, estimating competence needs for operation of PSV as well as achieving the acceptable level of availability performance. Critically analysis is a systematic screening process that utilizes a number of risk analysis tools including: Failure Modes, Effects and Criticality Analysis (FMECA), Fault Tree Analysis (FTA) and risk matrix and mentalities, for developing a list of critical components. The aim of this thesis is to study and review the available method of criticality analysis of PSV in Troms Offshore. Then based on reviewing standards, meeting with experts and using the experience of other industry is tried to find weaknesses of these methods, modify and improve such methods. In this thesis, the theoretical framework chapter covers a brief survey of risk analysis, criticality analysis and some of its method. In this part, it is focused more on the methods, which is used in the company to find the weaknesses and bottleneck of available method. The results of study show that FMECA is a useful tool for criticality analysis of mechanical and electrical equipment. Moreover, a risk matrix can be used as an effective tool to identifying the levels of risks and criticalities. It can help to risk management in decision-making.
