Non-linear analysis of pipeline installation
No full textThe paper presents an analytical basis for a very accurate yet extremely rapid analysis of the deformations of a pipe installed in any depth of water. The analysis is suitable for use on a desk-top computer and the speed of solution, 2-7 secs depending on water depth, permits a real-time assessment of the pipeline conditions during installation. The very rapid solution time of the method described here means that it can be used in real-time to monitor the lay-down geometry of a pipeline during installation and therefore can be an aid to minimising the occurrence of spans.
The analysis of a practical case shows the accuracy of the procedure and allows to draw a comparison with a finite element approach

Damage identification by a BEM approach
No full textIn the present paper the identification of the damage which may occur in the life of a brittle twodimensional
(2D) solid is examined by means of an inverse analysis. The damaged area is identified by
minimising the error between numerical results and experimental results of some static load tests. Some
design variables are introduced in order to describe the shape of the damaged area and the value of the
damage in some key points
