Risk Assessment and Reliability Analysis of Subsea Production Systems

Abstract In past years, offshore oil and gas accidents have often occurred. Environmental hazards have the capability of turning into very difficult to manage in addition with the modern technology limits and lack of a fail-safe operation that can identify, control and terminate the accidents. However, the offshore crude oil also natural gas search and development is expanding to deep-water and moving promptly to the subsea production systems. (SPS). Though, the complicate subsea equipment material besides frequency offshore disasters stimulated the consideration onto the risk analysis of subsea systems. Detection of the impact of deep-water oil and gas reserves in the subsea production system. However, loss of SPSs can contribute to massive industrial failure, severe natural pollution, and indeed serious disasters. Therefore, the reliability analysis and safety of SPS have turned into a dominant consideration. This study addresses on the hazards and risk conditions which must be concentrated in the subsea machinery associated within surface equipments. Furthermore, the risks identification also the risk investigation onto subsea “Xmas tree” system is brought out. An over-all risk avert procedure of subsea “Xmas tree” system is represented, also the reliability evaluation method. Moreover, several recommendations on subsea production maintenance and detection are given in this research. This paper is reviewing the following section, subsea production system, hazards or risk identification, environmental issues, hydrate problems, corrosion problems, safety issues, risk assessment on subsea “Xmas tree”, reliability issues of a subsea system.
