<p>A method of repairing a subsea pipeline which includes the steps of removing the damaged section of pipeline (10) and preparing the remaining ends (11,12) thereof for receiving adapter sleeves, positioning adapter sleeves (14) of a size which fit relatively closely around the exterior of the prepared end of the pipeline and have flanges of a size larger than would normally be used with the size of the tubular portion of the adapter sleeves,cold forging the prepared ends into tight gripping and sealing engagement with the tubular portions of the adapter sleeves and connecting a section of pipeline having flanges suitable in size for connecting to the adapter flanges to provide a complete connection between the ends of the pipeline. The adapter sleeve includes a tubular body and a connecting flange secured to the tubular body which is larger than normally used with a tubular body of the size of the adapter sleeve tubular body, and the adapter sleeve tubular body has an internal configuration suitable for gripping and sealing the exterior of the pipeline ends which are cold formed therein.</p> |
