ANALYSIS OF PIPELINE PULL-IN PROCEDURE USING SMALL SCALE MODELS

The structural elastic behaviour of steel pipelines during on- bottom pull-in procedure is investigated experimentally by using small scale models. It is shown that unevenness of sea-bed surface and non-uniform distribution of friction forces can lead to large-deflection bending stresses higher than the numerical results yielded by standard software packages, commonly used for design calculations. Due to foreseen difficulties in overcoming the drawbacks in practical and numerical procedures the off-bottom pull-in operation arises as an attractive alternative even for shallow waters.
