Despite continued advances in rubber technology, the design of elastomeric flexible connections, used in offshore pipelines transporting high-pressure/high-temperature hydrocarbon fluid/gas mixture, remains more of an art than a science, primarily due to the intricate behavior of rubber. The mechanical response of rubber is dependent on time, temperature and mode of loading. It is susceptible to explosive decompression damage. Rubber’s non-linear stress-strain curves, creep, hysteresis and other properties are influenced not only by the method of fabrication but also by age. If these characteristics are not accounted for properly, the result can be less precision in design compared with metals. At present, there are no codes or standards that directly address the design, analysis or evaluation of the elastomeric flexible connections used in offshore oilfield applications. Based on the results of the recent research, the significance of key parameters that affect the short term and long term structural performance of elastomeric flexible connections is presented in this paper.
