摘要
A method is described for controlled bending of a pipeline during the laying thereof in the sea, utilizing bend controlling/stopping means which are mounted on the pipeline as a sleeve and interact with the pipeline. To achieve cold bending under controlled conditions, the pipeline is weight loaded internally at the selected bending zone. The weight loading may be achieved by means of a flexible string of weight elements and/or by introducing into the pipe a suitable heavy, readily flowable weight mass, for example, drilling fluid.
