Abstract
The invention provides a drogue which is particularly useful for pulling an object through a confined space which has fluid flowing in it, such as a conduit or pipeline. The drogue comprises a body panel, with an even number of wing panels extending outwardly from the body panel and spaced evenly around it, and securing means associated with the body panel and with the end of each wing panel remote from the body panel. The invention also provides a combination of a drogue and an object to be pulled by the drogue. The object may be for example, a cable to be laid in a conduit or pipeline, or an inspection device (tethered or untethered) for inspection of a conduit or pipeline.
