The scope With increasing numbers of exible jumpers reaching the end of their design lives, the degradation analysis of exible jumpers is an emerging area of interest for the oil and gas industry. We were asked to perform a lifetime extension assessment of a pipeline system containing a series of exible jumpers in a North Sea eld. The solution We carried out a lifetime extension assessment of the pipeline system using the approach laid out in NORSOK ISO/TS 12747 and Y-002. For the exible jumpers, we were able to assess the degradation mechanisms of the carcass, PVDF liner and exible wires to determine if life extension of the exible jumpers was possible. This included: An examination of the likelihood of increased plasticity, ageing, embrittlement and creep of the PVDF An assessment
