Abstract
A method for performing operations using a water environment robotic system on a target section of pipeline located in an underwater environment is provided. The method includes the steps of deploying the underwater robotic vehicle into the water and visually inspecting the underwater environment to locate the pipeline and its plurality of weld joints. A cleaning operation is performed at one of the plurality of weld joints using the underwater robotic vehicle.
