Many analysts use simple lower‐order beam elements for the non‐linear analysis of curved beam and arch structures. The aim of the present paper is to indicate how one may add the effects of buoyancy, steady‐state current loading and riser top‐tension to such an idealization so that it may be used for the analysis of offshore pipes and risers. The current work is restricted to static two‐dimensional modelling but it paves the way for further work in three dimensions, which will include dynamics. Copyright © 2002 John Wiley & Sons, Ltd
