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.

Abstract: A system for refloating a grounded floatable vessel uses cylinder-shaped inflatable buoyant rollers that are placed under the vessel hull, inflated until they support the bottom hull and then caused to roll seaward while carrying the vessel into the water. An independently propelled vehicle pulls the vessel resting on the rollers into the water. An operator wirelessly controls inflation and deflation of the rollers to ensure stability of the vessel during the refloating operation.

Abstract: A binder formulation comprised of colloidal silica and a polymeric binder, preferably polyvinyl alcohol. A mineral pellet and related low temperature hardening process for making the same. The mineral pellet has sufficient strength to be transported and has sufficient strength for use in iron-making processes.
