Abstract: The present invention relates to a method and apparatus for cleaning an oil and gas well riser section or assembly. Even more particularly, the present invention relates to an improved method and apparatus for cleaning oil and gas well riser sections wherein a specially configured cap or pair of caps are fitted to the ends of the riser which enable pressure washing cleaning tools (or a camera) to be inserted into and through the riser cleaner fluid continuously recirculates so that relatively small volume of cleaning fluid (for example between about 700 and 1,000 gallons) is required. The cleaning process uses a volume of cleaning fluid that is discharged from the riser pipe at a relatively high temperature of about between 100 and 180° F. Such a high temperature cleaning fluid could possibly damage the pump that is used for supplying pressurized fluid to the cleaning tool.

Abstract: The present invention is directed to a method of cleaning and inspection of drilling mud carrying flow lines, each flow line having an inner surface. The method includes affixing a fitting to the flow line, the fitting having a main flow channel and a branch flow channel extending at an angle from said main flow channel. A first end portion of the fitting can have an attachment that enables connection of the fitting to the flow line at one flow line end portion. A second end portion of the fitting can have one or more doors that can be moved between opened and closed positions, the door or doors providing an opening that is not closed when the doors are in the closed position. A suction line can be connected to the branch flow channel. A cleaning tool can be guided first into the fitting and then into the flow line using a fluid carrying cable. The cleaning tool and jetting fluid can be used to clean drilling mud and debris from the inner surface of the flow line.

Abstract: The present invention relates to safety caps for lancing procedures, and a method of cleaning piping systems using said safety caps. More particularly, the present invention relates to an improved safety cap for oil and gas well pipes to be cleaned onsite that allows for the cap and lancing tools to be used in hard-to-reach places.

Abstract: The present invention is directed to a method of cleaning an oil and gas well riser section that has a central larger diameter tubular member having a flow bore and a plurality of smaller diameter tubular members connected to the central larger diameter tubular member, each smaller diameter tubular member having a flow bore. The method includes placing a fitting on an end portion of the riser section, the fitting covering an end of the larger diameter tubular member and the ends of the smaller diameter tubular members, wherein the fitting preferably has multiple openings including one or more centrally located openings and a plurality of circumferentially spaced apart outer openings that are spaced radially away from each of the one or more centrally located openings, said fitting having a drain opening.

Abstract: The present invention relates to a method and apparatus for cleaning an oil and gas well riser section or assembly on location offshore that includes a larger diameter central pipe and a plurality of smaller diameter pipes that are spaced radially away from the central larger diameter pipe. Even more particularly, the present invention relates to an improved method and apparatus for cleaning oil and gas well riser sections wherein a specially configured cap or pair of caps are fitted to the ends of the riser which enable pressure washing cleaning tools (or a camera) to be inserted into and through a selected one of the pipes including either a smaller diameter of the pipes or the central larger diameter pipe and wherein the cap continuously collects spent cleaning fluid and debris, allowing the cleaning process to be done on location without transporting the riser section back onshore.

Abstract: A method of cleaning a blow-out preventer stack that is preferably attached to an oil and gas well drilling platform including an initial disconnecting of the stack from the well so that it can be lifted. The stack is then preferably lifted vertically a selected distance. The method further includes lowering a water pressure cleaning tool into the stack bore using a hose, the tool preferably being attached to a lower end portion of the hose. Pressurized cleaning fluid is transmitted to the cleaning tool via the hose. A collection vessel is preferably placed below the stack and spaced from the stack so that cleaning fluid and cleaned debris exit the stack bore or interior and enter the vessel during cleaning. The method includes continuously discharging the fluid and debris from the vessel via a discharge outlet of the vessel.
