  • Pipeline repair habitat
    Patent number: 5775844
    Abstract: Embodiments of a pipeline repair habitat are disclosed which may be used to facilitate the repair of vertical underwater pipelines or risers. Two hollow, half-cylindrical shells are provided which form a stable, rigid shell around the section of pipe to be repaired. Structure is provided for introducing an atmosphere into the habitat which is breathable while most repairs are accomplished. Under certain conditions a non explosive atmosphere which is not breathable is introduced into the habitat so that welding may be safely performed. Various useful accessories are provided including an elevator by which a person accomplishing repairs may move up and down within the pipeline repair habitat.
