A system and method for pipeline inspection may include a transport module having a sensor arrangement configured to carry one or more sensors, and it may be movable longitudinally through the pipeline and circumferentially around an interior of the pipeline. The sensor arrangement may include a sensor and a sensor cover selectively disposable over the sensor for isolating the sensor from contact with the inside surface of a wall of the pipeline. The sensor cover may include a cleaning arrangement disposed proximate the sensor for removing debris from the sensor.
