Zusammenfassung:	A method of inspecting a water pipeline while the pipeline is full of water comprises providing a liquid-tight casing (1) housing a video camera (32) and lights (31), coupled to a cable (2) housing both optical and electrical conductors, A drogue (3) is attached to the casing (1) and the camera pod and drogue are launched through the sidewall of the pipeline via a launch chamber (7). The camera pod and cable are neutrally buoyant and can be deployed several kilometres along the pipeline for inspecting the pipeline and recovered again into the launch chamber (7). The advantage of this system over conventional systems is that much longer lengths of pipeline can be inspected from a single location.
