During the process of laying pipeline in shallow water,sometimes it is needed to lift the pipeline onto the barge deck.In this process the pipeline may failure due to large moment.The one point S-lifting is studied in this paper based on large deformation beam theory.By using two points lifting the problem of too large moment,to which the pipeline is subjected to during the lifting,is solved successfully.Correct arrangement of the mid-lifting point and corresponding mechanical behavior of pipeline is obtained by the use of shooting method.And the reliability of the present method is proved by comparison with the result from ANSYS.
