Abstract
A method for in-situ cleaning and inspecting of a tubular, comprising: deploying a closable housing to a tubular, hydraulically opening the closable housing and then hydraulically closing the closable housing around the tubular. Marine growth is removed from the tubular using a marine growth plough and high pressure water from at least one high pressure water jet unit, disposed a cleaning end of the closable housing. The cleaned tubular is inspected using at least one enclosable camera block containing at least one digital camera disposed on an inspection end of the closable housing. Signals from the cameras are communicated to a remote location. Hydraulic fluid and high pressure water are provided from the remote location to the closable housing. A tether is used to roll the closable housing along the tubular for continuous in-situ cleaning and inspection of the tubular without interrupting use of the tubular.
