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.

A cleaning device, especially an instrument cleaning device, having a thin, flexible threadlike object with a first straight end and a second looped end and a swab member attached to the looped end.

A drain snake may include a hollow body having a rearward end and a forward end, and a longitudinal axis extending between the rearward and forward ends. The forward end has a cable feed passage. The drain snake may further include a cable having a first portion coiled in the body around the axis in a location between the rearward and forward ends. The cable has a second portion extending out of the feed passage of the forward end of the hollow body. The drain snake also include a fastener extending through the body at the forward end and into the feed passage to secure and release the cable.

Methods and devices for actuating a clearance device to clear obstructive debris from medical tubes are disclosed. More particularly, a shuttle that includes a first primary magnetic element that is adapted to magnetically engage and translate a magnetic guide within a tube is disclosed. The first primary magnetic element is aligned so that a first primary magnetic field emanating therefrom is aligned substantially perpendicular to a longitudinal axis of the tube when viewed from a side of the shuttle.

A cable feeding device for a drain cleaner includes an upper body mounted on a support tube of the drain cleaner, a control subassembly, and a lower body. The upper body in which an upper feeding roller is held and the lower body in which two lower feeding rollers are held join each other. A cable inside a cable drum of the drain cleaner can extend through a region encircled with the upper and lower feeding rollers and can be resisted by the upper and lower feeding rollers for controllable forward or backward movements of the cable into a drain to be cleaned. The lower body has at least one separate mold-stripping hole for easy manufacturing of the upper and lower bodies in a plastic injection molding process. The upper and lower feeding rollers are not exposed to the outside for longer service life to clip the cable.

Systems and methods may utilize a two-axis stand configured with a locator moveable along two orthogonally oriented axes. The locator may scan a tube opening. A controller may position the locator and the two-axis stand to a) scan across a plurality of tube openings, b) locate the plurality of tube openings based on the scan, and c) activate a cleaning tool to clean tube interiors associated with respective tube openings. Control may be automated and/or based on user interaction with a user interface.
