Abstract
A damaged portion of a pipeline buried in a trench is gradually lifted from the trench to expose the damaged portion above water and provide easy access to the damaged portion. Inflatable roller bags are placed under the pipeline adjacent the damaged portion; the roller bags are then inflated in a controlled manner using a computer-based control unit. A control manifold is connected to the control unit and each of the roller bags by a separate air conduit allowing controlled bag-inflation and bag-deflation process for each roller bag. Once the pipeline is repaired, the roller bags are deflated, lowering the pipeline back to its original position in the trench.
