The over-bend of the flexible pipe will be subjected to obvious contact load during horizontal laying and failure may occur because of crushing. This usually restricts the application of horizontal laying in deep water. Therefore, it is significant to accurately estimate the contact load on the over-bend of the flexible pipe during laying. We carry out theoretical research on the over-bend contact load, deduce a simplified calculation formula, and investigate the key parameters which affect the contact load in the laying cases by numerical simulation. The results can offer a specific guidance for the over-bend contact load analysis in flexible pipe laying, and provide a reference for the laying design as well.

Key words: flexible pipe, horizontal laying, over-bend crushing, contact load
