Patent ID: 8007595

Claim:
A method for in-situ cleaning and inspecting of a tubular, the method comprising the steps of: deploying a closable housing to the tubular; hydraulically opening the closable housing and then hydraulically closing the closable housing around the tubular, wherein at least two sets of roller assemblies engage the tubular; removing marine growth from the tubular using a marine growth plough disposed on a cleaning end of the closable housing and water from at least one water jet unit on the cleaning end forming a cleaned tubular; inspecting the cleaned tubular using at least one enclosable camera block containing at least one digital camera and an imaging target plate disposed on an inspection end of the closable housing opposite the cleaning end for continuous digital imaging of the tubular as the closable housing engages and rolls along the tubular; communicating signals from the at least one digital camera to a remote location; providing hydraulic fluid from the remote location to the closable housing; providing water from the remote location to the at least one water jet unit; using a tether to roll the closable housing along the tubular for continuous in-situ cleaning and inspection of the tubular without interrupting use of the tubular; and transmitting a signal from the at least one enclosable camera block using a video camera via a ROV to a top side computer suite, wherein the top side computer suite comprises a processor with computer instructions for instructing the processor to process the signal at 50 frames per second in real time while simultaneously applying a mathematical model for continuous measurement of the tubular creating a geometric tubular profile.
