84437 - Platform Life Extension – Assessment Methodology for Pressure Vessel and Piping 

With global energy demand expected to increase substantially in the next few decades, the world will continue to need oil and gas developments to meet this. At the same time, new developments are difficult to sanction in the current market, it results that platforms life extension is an excellent way to meet increase demand. There are new fields to be exploited where an existing platform from another field could be reused economically. With the squeeze on capital expenditures, there is now incentive to find economical ways to extend the life of existing platforms. Selection of the most suitable strategy among a wide range of potential options to extend the lifetime of equipment remains a challenging task. In order to tackle this challenge, it is crucial to develop analytical tools and methods capable to anticipate actions and costs required to keep the equipment operational at an adequate level of integrity for the expected life time of the asset. This paper present systematic approach for the life extension assessment of the pressure vessels and piping of an aging offshore asset. The potential of the proposed methodology is demonstrated through a case study involving an offshore asset which was constructed in the mid-1980s.
