Method of fixing a broken oil pipe

Abstract

The usual safety feature of oil pipes is the shut-off valve. Whenever there is a need, such a valve can be closed, and oil is prohibited from spilling into the surroundings. However, the shut-off valve may sometimes be inaccessible. It may be buried deep in the mud, or even worse, there may be no shut-off valve. Such an oil spill could prove disastrous. Fortunately, our invention would provide a solution to just such a situation. We would need to send submarine robots to the scene of the accident. These robots, controlled from the ship on the surface, would insert our specially designed hydraulic head into the pipe. This head would then seal the pipe, stopping any further oil spill.
