dc.description.abstract | In this master thesis the author carries out the research of the process piping integrity
problems on ageing offshore installations located on the NCS in the context of M&M project
activity. The author describes briefly conventional M&M projects, which are being performed
on platforms and piping discipline’s role on them. The emphasis of this thesis work is placed
on corrosion of process piping and pipe supports, so the typical corrosion forms for them in
offshore environment are discussed, with more detailed description of corrosion under
insulation and pipe support related corrosion as the two most severe and typical mechanisms
of corrosion. The author presents material alternatives for process piping systems with
different properties and degree of corrosion resistance, analyses performance of stainless
steel and GRE piping materials as the most exploited on M&M offshore projects to withstand
corrosion. Piping vibration problem is discussed in terms of modification impact on ageing
piping systems. Through the case study from one of the ageing platforms the author raises
the issue of lack of management attention to piping integrity problems. Then the author
discusses piping system integrity barriers to withstand corrosion for all the stages of the
piping system life cycle, where he underlines that the role the management is vital for the
barriers’ effectiveness. By indicating on excessive focus of senior management of M&M
service provider companies on financial indicators and insufficient attention to non-financial
ones, the author emphasizes the importance of utilization of proper management systems,
like the Balanced Scorecard, in order to achieve balanced performance of all organization’s
domains. Achieving of such an organizational level ensures M&M services provider to
improve rendering of services so that the effectiveness of piping system integrity barriers,
carefully developed and maintained, will provide sustainable work of piping system for years.
As the result the operator gets reduced OPEX of piping systems contributing to extension of
economic life of the mature field. | no_NO |
