The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

An investigation on the wave-induced motion responses of a FPSO stationed in Schiehallion field approximately 140km to the west of the Orkney Islands UK is presented. The Schiehallion FPSO and her turret mooring system are subject to harsh North East Atlantic weather conditions. In this study, a frequency-domain method and a fast time-domain technique are employed to estimate wave-induced extreme excursions and the resulting tensions on the mooring lines. Both the first-order and second-order motions are considered. The calculated results of wave frequency and low frequency motions of the FPSO and the corresponding maximum line tensions by these methods are compared and discussed.
