Oil pipeline may only be coated against corrosion once they are attached to the well-head. Electric components can be dangerous in such an environment, as ignition sparks can potentially cause a fire.Pipes carrying oil from the seabed to the platform need to be coated to prevent the salty environment corroding the metal over time.When engineers at Covercat Spray Systems were looking to develop an actuation system to operate its Pipe Snake coating machine in the Norwegian and North American oil fields, they decided that electric components were too risky. Sparks from electric circuitry, given off during a machine's start-up, could cause a fire - given the close proximity of the oil wells.
