A New Rigid Jumper VIV Response Model: JIP Development

Abstract

Recognizing the need to address the challenges associated with the VIV assessment of rigid jumpers, a joint industry project (JIP) was launched in December 2014. The JIP was based on the model test data supplied by ExxonMobil. Through the JIP study, measured responses from tow tests were used to develop new response curves for jumper systems and compared against the existing DNV GL-RP-F105 curves. This paper presents details of the validation of model test data; processing of test data for response curve development; classification and interpretation of jumper response and; the two new response models developed for VIV assessment of rigid jumper systems. The response model developed through the Jumper VIV JIP forms the first of its kind for the VIV of non-straight (complex) pipe systems.
